00;00;02;23 - 00;00;05;18
Speaker 1
Hey! Gemini!
00;00;05;20 - 00;00;08;19
Speaker 2
Hey, there. What can I do for you?
00;00;08;22 - 00;00;12;28
Speaker 1
Do you mind if I record this for a podcast?
00;00;13;00 - 00;00;16;02
Speaker 2
Not at all. Feel free to record our conversation.
00;00;16;05 - 00;00;27;05
Speaker 1
Okay. Today I want to talk about the X. I want to explore the healing properties of sound.
00;00;27;07 - 00;00;35;12
Speaker 2
Sounds like a fascinating topic. So what about sound healing is most interesting to you?
00;00;35;15 - 00;00;42;28
Speaker 1
I don't know. Can you give me just kind of a detailed rundown of anything you know about it?
00;00;43;00 - 00;01;05;29
Speaker 2
Sure thing. Sound healing is the practice of using different sounds to promote relaxation and healing. People believe that it can help with stress, anxiety, and even some physical ailments. There are a few different techniques like singing bowls, chanting and listening to specially designed soundtracks.
00;01;06;01 - 00;01;15;09
Speaker 1
Okay. Let's go in to how they can help you relax.
00;01;15;12 - 00;01;34;13
Speaker 2
So it's less about conscious relaxation and more about your body responding to the vibrations. Sound waves have this amazing ability to resonate with our bodies on a cellular level. When you hear those tones and rhythms, it can trigger a deep sense of calm. Kind of like a gentle massage for your brain.
00;01;34;15 - 00;01;44;09
Speaker 1
Okay, that's exactly where I wanted to go. I want to get into the nitty gritty of, I guess, the physics of it.
00;01;44;11 - 00;02;11;21
Speaker 2
Okay, so when you hear a sound, it's actually a vibration traveling through the air. These vibrations hit your eardrum, and that's how you perceive the sound. But those vibrations don't just stop at your ears. They travel through your whole body. Now, the cool part is that different frequencies of sound can have different effects on your body. Some frequencies might relax your muscles, while others could stimulate your brain in certain ways.
00;02;11;24 - 00;02;24;13
Speaker 1
Can we go into the extreme edge cases of what sound can do to the body that does not include your eardrums?
00;02;24;15 - 00;02;46;22
Speaker 2
So there's a lot of research on how sound waves can affect things like muscle tension and even bone healing. But when it comes to stuff that doesn't involve the ears, things get a little less direct. You see, it's not like you can blast someone with a specific frequency and zap them with healing energy or something. It's more about subtle changes that build up over time.
00;02;46;24 - 00;02;58;03
Speaker 1
Okay, I would like to. I would love for your answers to be, about three times longer and dense with information.
00;02;58;06 - 00;03;17;01
Speaker 2
So there's a lot of interest in how sound waves can affect things like muscle tension and even bone healing. But when it comes to stuff that doesn't involve the ears, things get a little less straightforward. You see, it's not like you can blast someone with a specific frequency and zap them with healing energy or something. It's more about subtle changes that build up over time.
00;03;17;03 - 00;03;34;07
Speaker 2
Think of it like this when you hear really loud noise, it can make your whole body tense up, right? That's a pretty obvious physical reaction to sound. But there's also a lot of research showing that certain frequencies can actually promote relaxation and reduce stress. It's all about finding the right kind of sound and using it in the right way.
00;03;34;13 - 00;03;53;02
Speaker 2
Some people believe that sound can even have a deeper impact, like on the cellular level. The idea is that these vibrations might be able to influence the way our cells function. But this is still a pretty new area of research, so there's not a ton of scientific proof yet.
00;03;53;05 - 00;04;12;25
Speaker 1
Okay. Let's go. Let's talk about it real quick on the negative side, just to see if we can get, an example has the as any state military use sound base weapons that don't just blast loud sound.
00;04;12;28 - 00;04;39;15
Speaker 2
Absolutely. There is a darker side to sound technology. While things like singing bowls are meant to promote relaxation. There are devices designed to do the opposite. The military has researched sonic weapons that can disorient or incapacitate enemies with high pitched noises, or even low frequency vibrations that cause physical discomfort. These are just theoretical either. Some militaries have actually used them in the field.
00;04;39;18 - 00;04;51;26
Speaker 1
Can you give me some historical, factual examples of times that sonic weapons have been used in the field?
00;04;51;28 - 00;05;14;16
Speaker 2
There are a few well-documented cases. One of the most infamous incidents happened in the Cuban embassy in London. Back in the 80s, diplomats started complaining of dizziness, nosebleeds and hearing loss. Some blamed a sonic attack, though the cause was never officially confirmed. Then there's the long range acoustic device, or LRA, and it's basically a really powerful speaker that can be used for crowd control.
00;05;14;22 - 00;05;22;13
Speaker 2
They've been deployed by navies to ward off pirates, and even used in some domestic situations by police.
00;05;22;15 - 00;05;29;13
Speaker 1
Okay. Can you go ahead and describe this lrad or whatever it is?
00;05;29;16 - 00;05;57;21
Speaker 2
You're probably referring to a long range acoustic device or Lrad for short. It's basically a really powerful speaker that can be used for crowd control. They've been deployed by navies to ward off pirates and even used in some domestic situations by police. These things are loud like excruciatingly so. They can cause pain, disorientation, and even nausea. You definitely wouldn't want to get hit with one of these things.
00;05;57;24 - 00;06;05;25
Speaker 1
Okay. Can you go into the specifics of the Cuban Embassy in London?
00;06;05;28 - 00;06;28;05
Speaker 2
The Cuban embassy stuff is a little murky. Basically, diplomats stationed there started reporting all sorts of weird symptoms headaches, dizziness, hearing loss, the works. Some blamed sonic attacks. But the truth is, nobody really knows for sure what happened. There were a lot of theories floating around, but nothing ever got officially confirmed.
00;06;28;07 - 00;06;32;11
Speaker 1
And when did this occur?
00;06;32;13 - 00;06;44;25
Speaker 2
The Cuban embassy stuff started happening sometime around 2016. It went on for a while and there were a bunch of investigations, but they never figured out what was really going on.
00;06;44;27 - 00;06;49;16
Speaker 1
And so is this in Cuba or in London?
00;06;49;18 - 00;06;57;29
Speaker 2
It was in the London Embassy of Cuba.
00;06;58;01 - 00;07;07;22
Speaker 1
Okay. I need you to, specify on where this was properly.
00;07;07;24 - 00;07;17;08
Speaker 2
The Cuban embassy was located in Belgravia, London. It's a pretty upscale neighborhood known for its embassies and big fancy houses.
00;07;17;10 - 00;07;21;16
Speaker 1
So it wasn't in Cuba.
00;07;21;19 - 00;07;33;08
Speaker 2
You're absolutely right. The Cuban embassy was located in London, not in Cuba. The good catch.
00;07;33;10 - 00;07;48;17
Speaker 1
Okay, I'm somewhat familiar with that one, but can you give, kind of a description on what was going on there and what different theories are.
00;07;48;20 - 00;08;10;01
Speaker 2
All right, so in the Cuban embassy in London, a bunch of diplomats started complaining about these really weird symptoms, like headaches, dizziness. And some people even had nosebleeds. It was super strange because there was no obvious cause, like a chemical leak or something like that. This led to a lot of theories about what was going on. Some people thought maybe it was a sonic weapon, some kind of high pitched noise that was messing with people's heads.
00;08;10;07 - 00;08;23;12
Speaker 2
Others thought maybe it was something else, like microwaves or even psychological warfare. Anyway, it was a big deal at the time, and there were investigations all over the place, but they never really figured out what caused it.
00;08;23;14 - 00;08;29;09
Speaker 1
What about other examples of this happening in the real world?
00;08;29;11 - 00;08;47;23
Speaker 2
There have been other incidents where sonic weapons or similar devices have been used. Some militaries have experimented with them for crowd control or even to disable enemy combatants. But using them in actual warfare is a whole other story. There aren't many confirmed examples of that happening yet. It's worth noting that sometimes sounds get blamed for things that have other causes.
00;08;47;28 - 00;09;07;25
Speaker 2
A classic example is infrasound. Really low frequency sounds that are sometimes blamed for feelings of unease in old buildings. It's a fun theory, but there's not a lot of solid evidence to back it up.
00;09;07;27 - 00;09;16;01
Speaker 1
There's got to be another example other than the Cuban embassy example.
00;09;16;03 - 00;09;40;07
Speaker 2
All right. Let's dig into some other examples. There was a case in 2018 where U.S. diplomats and their families in China started reporting similar symptoms to what happened in London. Things like dizziness, headaches and trouble concentrating. Many suspected some kind of sonic attack, but the cause was never officially confirmed. Also, there have been reports of police using sonic weapons for crowd control, but it's hard to find solid examples where these were the only tools used.
00;09;40;13 - 00;09;53;08
Speaker 2
Often things like tear gas or rubber bullets were involved too.
00;09;53;11 - 00;10;00;06
Speaker 1
Was this 2018 incident also in an embassy?
00;10;00;08 - 00;10;13;24
Speaker 2
Yeah. The 2018 incident also involved U.S. diplomats and their families. But this time in China, it's kind of eerie how similar the symptoms were to what happened in London.
00;10;13;26 - 00;10;20;15
Speaker 1
Is there a third incident that also mirrors this?
00;10;20;17 - 00;10;50;10
Speaker 2
It's a little tough finding incidents that perfectly mirror the embassy cases, but there is one that has some similarities. In 2017, there were reports of mysterious illnesses affecting U.S. personnel at the embassy in Havana, Cuba. People experienced symptoms like headaches, dizziness and difficulty sleeping. Some suspected sonic attacks, but the exact cause remains under investigation.
00;10;50;12 - 00;11;07;26
Speaker 1
Is there a fourth embassy that's undergone this?
00;11;07;29 - 00;11;11;09
Speaker 1
Gemini year. There.
00;11;11;11 - 00;11;13;27
Speaker 2
I'm here. What's on your mind?
00;11;13;29 - 00;11;19;04
Speaker 1
Is there a fourth embassy that's happened like this?
00;11;19;07 - 00;11;41;01
Speaker 2
So there aren't any widely reported incidents that perfectly mirror the embassy cases in London, China and Cuba. But it's possible there could be less publicized ones or situations where sonic weapons were used without it being the main focus. Would you like to explore some of the potential effects of sonic weapons in more detail, or maybe look into other unusual weapons and their history?
00;11;41;03 - 00;11;48;08
Speaker 1
No. Let's go back to the healing side of things.
00;11;48;11 - 00;12;07;27
Speaker 2
So we were just talking about how sound waves can be used for healing and relaxation, but there's also a lot of interest in using sound for more practical stuff like cleaning things. Ultrasonic cleaners use super high frequency sound waves to agitate liquids, which can help break down dirt and grime. It's kind of like giving your jewelry a sonic bath.
00;12;08;00 - 00;12;23;03
Speaker 1
No, I want to talk about specific research that we have that documents the interaction of sound waves with maybe human cells.
00;12;23;06 - 00;12;46;26
Speaker 2
There's definitely research on how sound waves interact with human cells. It's a bit tricky, though, because a lot of it focuses on medical procedures like ultrasound, which use high frequency sound waves to create images of the inside of your body. But there's also research into things like using ultrasound to deliver drugs directly to cells, or even potentially using it to disrupt cancer cells.
00;12;46;29 - 00;12;55;18
Speaker 1
Okay. Can you tell me, with detail, how an ultrasound works?
00;12;55;20 - 00;13;16;25
Speaker 2
Okay, so imagine this an ultrasound machine sends out super high pitched sound waves that your ears can't hear. These waves travel through your body and bounce off different tissues and organs. The machine then picks up those echoes and uses them to create a picture. Think of it like sonar, but instead of mapping the ocean floor, it's mapping the inside of your body.
00;13;16;27 - 00;13;24;09
Speaker 1
And so why do they use really high pitch sound versus very low pitch sound?
00;13;24;12 - 00;13;50;05
Speaker 2
So it's all about getting that detailed picture. Those high frequency sound waves are a lot shorter, kind of like ripples on a pond when you drop in a tiny pebble. These short wavelengths can bounce off smaller things inside your body, giving you that detailed image. Lower frequency sound waves are longer. Like when you have those big rolling waves at the beach, they might be good for getting an overall picture, but they wouldn't give you the same level of detail for seeing smaller stuff.
00;13;50;08 - 00;13;57;20
Speaker 1
Got it. Higher pitch. Higher frequency. Higher resolution.
00;13;57;22 - 00;14;09;04
Speaker 2
Yep. You got it. Higher pitch means higher frequency, which gives you a finer picture of what's going on inside you.
00;14;09;06 - 00;14;16;04
Speaker 1
Can you talk about the, the sound waves guiding medicine?
00;14;16;06 - 00;14;36;19
Speaker 2
So there's a lot of interest in using sound waves to deliver medicine. Kind of like a sonic tractor beam for drugs. The idea is that you could use ultrasound to create tiny bubbles in the body, and those bubbles would then carry the medicine right to where it needs to go. It's still early days for this technology, but there's a lot of potential, especially for things like cancer treatment.
00;14;36;21 - 00;14;42;09
Speaker 1
So how does it create bubbles?
00;14;42;11 - 00;15;04;17
Speaker 2
So it's actually kind of cool. They use something called microbubbles. Think of them like really tiny bubbles sometimes made of things like albumin or fat. They inject these microbubbles into your bloodstream. Then they use ultrasound to hit those microbubbles with sound waves. This causes the bubbles to vibrate really fast, which creates a lot of energy. That energy can be used to do things like open up cell membranes.
00;15;04;24 - 00;15;13;09
Speaker 2
So drugs can slip inside.
00;15;13;11 - 00;15;21;20
Speaker 1
So targeted high frequency sound can open cell membranes.
00;15;21;22 - 00;15;36;00
Speaker 2
Yep, that's the idea. You use focused ultrasound to hit those microbubbles right where you want the medicine to go. The vibrating bubbles basically create a tiny opening in the cell membrane, letting the drugs slip right in.
00;15;36;03 - 00;15;41;23
Speaker 1
And these are bubbles of like, lipids that have been injected.
00;15;41;25 - 00;15;54;03
Speaker 2
Yep. They use tiny bubbles made of things like lipids. These bubbles are already in the bloodstream. And then they use the ultrasound to activate them right where they need to be.
00;15;54;05 - 00;15;58;20
Speaker 1
Do they damage the cell membrane?
00;15;58;22 - 00;16;18;06
Speaker 2
So the goal isn't to damage the cell membrane, but to create a temporary opening. Think of it like a gate. You want to open it just long enough for the medicine to get through, and then have it close right back up. There's always a risk of damage with any medical procedure, but the idea is to minimize that risk by being really precise with the ultrasound.
00;16;18;09 - 00;16;24;11
Speaker 1
So how do they move the lipids with sound?
00;16;24;13 - 00;16;39;11
Speaker 2
They don't really move the lipids. The lipids are already in the bloodstream. So they're kind of just hanging out there until they're needed. When it's time to deliver the medicine they use the ultrasound to activate the lipids right where they need to be. It's like those lipid, the little soldiers just waiting for the command to go into action.
00;16;39;14 - 00;16;43;24
Speaker 1
How do the lipids know where to be?
00;16;43;27 - 00;17;02;22
Speaker 2
That's a great question. So the lipids themselves don't really know where to be. They're just floating around in your bloodstream. The trick is in how they design the lipids and the medicine they carry. You see, they can engineer these lipids to be attracted to certain things like proteins found on cancer cells. That way when they're injected, they naturally gravitate towards the tumor.
00;17;02;25 - 00;17;08;05
Speaker 2
It's like having a little homing beacon built right into the medicine.
00;17;08;07 - 00;17;20;27
Speaker 1
So the the issue that we're solving with sound is that these molecules can get right up to the other thing, but they can't actually get in.
00;17;20;29 - 00;17;43;25
Speaker 2
Yep, that's exactly it. Think of it like being right outside your front door, but not having a key to get inside. These molecules can get really close to the cells they need to target, but they can't actually get inside to do their work. The ultrasound and microbubbles are basically like giving those molecules a little key to unlock the door.
00;17;43;28 - 00;17;52;13
Speaker 1
I guess I want to go into a little bit more about these microbubbles.
00;17;52;15 - 00;18;16;03
Speaker 2
All right. So these microbubbles are pretty amazing. They're basically tiny spheres filled with air or gas, and they're usually coated in some sort of material like lipids or proteins. This coating is important because it helps them stay stable in the body, and can also be used to target specific cells. You can think of them like little balloons, but way smaller and with a special coating.
00;18;16;05 - 00;18;21;01
Speaker 1
And are those the things that are injected?
00;18;21;03 - 00;18;33;03
Speaker 2
They inject these microbubbles into your bloodstream. Think of them like really tiny bubbles, sometimes made of things like albumin or fat.
00;18;33;05 - 00;18;41;10
Speaker 1
Why are they bubbles? And not just, lipids? Why do they have air in them?
00;18;41;12 - 00;19;07;22
Speaker 2
Okay, so the air or gas inside the microbubbles is what makes them so special. When you hit them with ultrasound, that air or gas inside starts vibrating really fast. It's kind of like blowing into a balloon really hard. It makes the balloon vibrate. This vibration creates a lot of energy, and that energy can be used to do things like open up cell membranes or even break up small clumps of stuff.
00;19;07;25 - 00;19;16;19
Speaker 1
This sonic energy has more effects on air than it does on water.
00;19;16;21 - 00;19;36;03
Speaker 2
Actually, sound waves travel faster in water than in air. So in a way, sonic energy has more of an effect in water than in air. But when it comes to these microbubbles, it's the vibration itself that matters, not necessarily the speed of the sound wave. Would you like to know more about how these microbubbles are used in specific medical treatments?
00;19;36;05 - 00;19;41;25
Speaker 1
Yes, please.
00;19;41;27 - 00;19;46;01
Speaker 1
Yes, I would like that.
00;19;46;03 - 00;20;09;12
Speaker 2
So one of the most exciting uses for these microbubbles is an ultrasound imaging. Normally when you get an ultrasound, it's kind of hard to see blood flow. But if you add microbubbles into the bloodstream, they show up really bright on the ultrasound. This makes it a lot easier for doctors to see things like blood clots or even small tumors.
00;20;09;14 - 00;20;23;10
Speaker 1
Okay. Can you give me any other instances besides the targeted microbubbles? Think about, medical use of sound.
00;20;23;12 - 00;20;43;17
Speaker 2
So we've already talked about how ultrasound can be used to image things inside your body and deliver drugs. But there's another cool application called lithotripsy. It's basically like using sound waves to blast kidney stones into tiny pieces. They use super powerful sound waves to create shock waves that break up those pesky kidney stones. Just a reminder that I don't provide medical advice or diagnoses.
00;20;43;22 - 00;20;52;11
Speaker 2
You should always talk to a medical professional.
00;20;52;14 - 00;21;13;03
Speaker 1
Just. Okay. Can you, really dig into this? The logistics of how this lithotripsy turns sound. So, tech uses sound waves to break up kidney stones.
00;21;13;05 - 00;21;40;11
Speaker 2
Okay, so they use something called shockwave with a trip to blast those kidney stones. They basically focus a whole bunch of sound energy into a super small spot where that kidney stone is hiding. This creates a shockwave that hits the kidney stone and breaks it into tiny pieces that can be easily passed. It's kind of like using sound to create a tiny explosion right where you need it.
00;21;40;13 - 00;21;52;00
Speaker 1
Okay, can you kind of give us more detail from, like, the physics side about how this explosion occurs?
00;21;52;02 - 00;22;08;02
Speaker 2
So it's not really an explosion like you'd think of with dynamite. It's more like creating a really intense pressure wave. They use a machine to focus a bunch of sound energy into a very small spot where that kidney stone is. This creates a super high pressure wave that hits the kidney stone with a ton of force, causing it to break apart.
00;22;08;07 - 00;22;21;00
Speaker 2
It's like focusing the energy of a really powerful speaker into a tiny point.
00;22;21;03 - 00;22;33;23
Speaker 1
Okay, so and at like an atomic and wavelength scale, how does this work? Or the is it the wavelengths like crushed together.
00;22;33;26 - 00;22;52;16
Speaker 2
So at the atomic and wavelength scale it's all about the energy of the sound wave. When you focus that sound energy into a tiny spot, the atoms in the kidney stone basically start vibrating really, really fast. Think of it like shaking something so hard it breaks apart. And yes, you could think of the wavelength as being compressed in that focused spot.
00;22;52;20 - 00;23;03;08
Speaker 2
It's like taking a long, stretched out wavelength and squeezing it down into a tiny little burst of energy.
00;23;03;11 - 00;23;10;18
Speaker 1
Okay. Are there other instances of medical use of sound waves?
00;23;10;21 - 00;23;36;01
Speaker 2
Yep. There are a few other cool medical uses for sound waves. We already talked about how ultrasound can be used to deliver drugs, but it can also be used to heat up specific tissues in the body. Doctors sometimes use this to treat tumors or to relieve pain. There's also a technique called Mr. guided focused ultrasound. It combines the power of ultrasound with MRI imaging to treat things like tumors and neurological disorders.
00;23;36;03 - 00;23;40;09
Speaker 1
Okay. Can you go further into that topic?
00;23;40;12 - 00;24;09;01
Speaker 2
So misguided focused ultrasound is basically a combination of two powerful tools. You've got MRI, which is amazing at creating detailed images of the inside of your body. And then you've got focused ultrasound, which we've already talked about. It's like having a really precise laser for sound waves. By combining these two doctors, get a super clear picture of what they're targeting, and then they can use the ultrasound to zap it with energy.
00;24;09;03 - 00;24;21;11
Speaker 1
Has anybody built, like a larger scale version of this to not use on the human body? But maybe like pop a balloon or something like that?
00;24;21;14 - 00;24;39;21
Speaker 2
Yep. You could use something similar to pop balloons, but you'd need a much lower frequency of sound instead of the super high pitched stuff we've been talking about. You'd want something more like a really deep bass sound. You could even use focused sound to create a pressure point that would pop the balloon without damaging anything else.
00;24;39;23 - 00;24;46;09
Speaker 1
Why would you need it? A lower frequency?
00;24;46;12 - 00;25;03;27
Speaker 2
So it's all about the size of the target. Higher frequency sound waves have shorter wavelength, which means they're better for smaller targets like cells or kidney stones. But for something bigger, like a balloon, you want a lower frequency with a longer wavelength. Think of it like trying to pop the balloon with a needle versus trying to pop it with your finger.
00;25;03;29 - 00;25;13;03
Speaker 2
You need a bigger tool for a bigger job.
00;25;13;05 - 00;25;22;22
Speaker 1
What would happen if you did the same thing with, shorter wavelengths at the balloon?
00;25;22;24 - 00;25;43;15
Speaker 2
If you used a shorter wavelength, like from a higher frequency sound on a balloon, it would probably just pass right through without doing much. It's like trying to pop a balloon with a needle that's too small. It won't do the trick. You need a longer wavelength, like from a lower frequency sound, to create that pressure wave that's strong enough to rupture the balloon.
00;25;43;18 - 00;26;03;07
Speaker 1
Okay, so we've covered a lot of instances of very targeted, uses. Are there any other more broad uses of sound and health having to do with maybe vibrations?
00;26;03;09 - 00;26;32;01
Speaker 2
Absolutely. There's a whole world of sound therapy that uses vibrations in a more general way. You've probably heard of things like sound baths, where you basically soak up the vibrations from instruments like singing bowls. People also use vibration platforms, kind of like mini trampolines for workouts or relaxation. These vibrations can help with everything from circulation to stress relief.
00;26;32;03 - 00;26;39;18
Speaker 1
What kind of sound therapy that has scientific backing exists?
00;26;39;20 - 00;27;02;05
Speaker 2
So there's a growing body of research on sound therapy, but it's still a relatively new field. Some studies show promise in using sound to manage things like anxiety, depression, and even pain. Techniques like binaural beats, which use slight differences in frequency to create brainwave patterns, are getting attention. You could ask me to find some specific studies if you're interested.
00;27;02;07 - 00;27;11;07
Speaker 1
Yeah. I would like you to go into that thing that you just mentioned, like buying or something.
00;27;11;10 - 00;27;38;23
Speaker 2
Sure thing. Binaural beats are a really interesting phenomenon. Basically, you listen to a tone in one ear that's slightly different from the tone in the other ear. Your brain tries to merge these two tones, and that creates a third tone called a binaural beats. The cool thing is that these binaural beats can influence your brainwaves, which might help with things like relaxation, focus, or even creativity.
00;27;38;26 - 00;27;48;18
Speaker 1
Can you give us some specific research that has been done around this?
00;27;48;21 - 00;28;07;22
Speaker 2
There's a lot of research on binaural beats, but it's a bit of a mixed bag. Some studies show positive effects on things like anxiety and focus, while others don't find much of a difference. One thing to keep in mind is that a lot of the research is preliminary, and we need more studies to really understand how binaural beats work and who might benefit the most.
00;28;07;25 - 00;28;15;26
Speaker 1
All right, well, why don't you just go into one that has positive effects?
00;28;15;28 - 00;28;35;08
Speaker 2
Okay. There was a study published in the Journal of Alternative and Complementary Medicine that looked at binaural beats and anxiety. They found that people who listened to binaural beats for a month had lower levels of anxiety compared to people who didn't. It's just one study, and it's always good to look at more research, but it does show some promise for using binaural beats to help with anxiety.
00;28;35;10 - 00;28;57;06
Speaker 1
Okay, what is the theory behind, listening to one tone in one ear and one tone in the other, and then your brain. And it has to like, work to put those together or something. Can you give me a little bit more background on how that is supposed to work?
00;28;57;08 - 00;29;13;17
Speaker 2
Absolutely. So your brain is constantly processing information, and part of that is figuring out where sounds are coming from. When you hear a sound in one ear, your brain uses that information to start building a picture of where that sound is located. Now, with binaural beats, you've got slightly different tones in each ear, so your brain gets a little confused.
00;29;13;22 - 00;29;23;12
Speaker 2
It starts working overtime trying to figure out what's going on, and that mental effort can lead to changes in your brainwave patterns. Does that make sense?
00;29;23;14 - 00;29;29;09
Speaker 1
Yeah, keep going from there.
00;29;29;11 - 00;29;59;15
Speaker 2
So when your brain waves start to change, it can have an effect on your mental state. For example, certain brainwave patterns are linked to relaxation, while others are linked to focus or creativity. Binaural beats might be able to guide your brainwaves into a specific pattern, which could help you feel calmer, more alert, or whatever you're aiming for. It's like gently nudging your brain in the right direction.
00;29;59;18 - 00;30;04;19
Speaker 1
It seems like, it seems like that would be.
00;30;04;19 - 00;30;06;00
Speaker 2
It seems like what.
00;30;06;02 - 00;30;24;22
Speaker 1
Seems like that would be kind of, hard to deal with, like, annoying. But I guess it would give your brain a little bit of, like, mild adversity. Kind of like working out, I guess.
00;30;24;25 - 00;30;42;13
Speaker 2
Yeah. It could feel a little weird at first. Like your brain's not quite sure what to do. But the idea is that after a while, it starts to settle into this new pattern, and you might actually find it kind of soothing. It's like any new skill, it takes practice before it feels natural.
00;30;42;15 - 00;30;49;02
Speaker 1
Okay. Can you go into the research about the bowls?
00;30;49;05 - 00;31;07;01
Speaker 2
Sure thing. Singing bowls have been used for centuries in some cultures, but there's not a ton of scientific research specifically on them. Most of the studies focus on how sound vibrations in general can affect things like stress and relaxation. There's some evidence that suggest listening to singing bowls can lower your heart rate and blood pressure, which are signs of relaxation.
00;31;07;05 - 00;31;16;21
Speaker 2
But we need more research to really understand how they work and who might benefit the most.
00;31;16;23 - 00;31;41;11
Speaker 1
I think that everybody would probably agree that sound and music and stuff like that can be relaxing. I'm sure it's different for everybody, but what is it about music specifically that can have a relaxing effect?
00;31;41;14 - 00;31;59;14
Speaker 2
That's a great question. Music is a powerful tool, and it's true. The reasons it relaxes us can be really personal, but there are a few things at play. First, music can trigger emotions and memories, and those feelings might be calming. Second, the rhythm and melody of music can actually change our brainwave patterns, bringing on a more relaxed state.
00;31;59;20 - 00;32;11;29
Speaker 2
Finally, it's possible that music distracts us from whatever's causing us stress. Kind of like a mental vacation.
00;32;12;01 - 00;32;20;21
Speaker 1
Okay, I want you to go into rhythm, changing our brainwave pattern.
00;32;20;24 - 00;32;46;21
Speaker 2
So it's less about the rhythm itself and more about something called entrainment. Basically, your brain has its own natural rhythm. And when you listen to music with a similar rhythm, your brainwaves start to sync up with the beat. It's like finding your groove with the music. When this happens, it can trigger a relaxation response in your body.
00;32;46;23 - 00;32;58;08
Speaker 1
This, I imagine, is related to why humans find music or rhythmic beats pleasant.
00;32;58;10 - 00;33;15;18
Speaker 2
Yeah, that's a big part of it. We're wired to respond to rhythm. Think about clapping along to a song or tapping your foot. It's a natural reaction. There's a sense of satisfaction and even comfort that comes from feeling that connection to the beat.
00;33;15;20 - 00;33;43;13
Speaker 1
I'm sure there's got to be a lot of research about this, but I want you to give me a in-depth description of why humankind enjoys music, not on like, a very broad scale, but a very detailed kind of, almost biological innate perspective.
00;33;43;15 - 00;34;05;19
Speaker 2
Okay, so this is a seriously complex question, and we're really just scratching the surface with current research. But here's what we do know. First, there's the whole reward system thing. When we experience something pleasurable. Our brains release feelgood chemicals like dopamine. Music seems to trigger this reward system in a big way. There's even research showing that music can activate the same reward pathways in our brains as food or sex.
00;34;05;22 - 00;34;28;05
Speaker 2
Second, there's the social connection piece. Music has always been a way for humans to bond and connect with each other. Singing, dancing, and playing instruments together creates a sense of community and belonging. Finally, there's the idea that music might have some evolutionary advantages. Some theory suggests that our love of music is rooted in our need for communication and social bonding skills that were crucial for survival in our ancestors.
00;34;28;12 - 00;34;32;24
Speaker 2
Does that give you a little more insight?
00;34;32;26 - 00;34;46;21
Speaker 1
Yeah, I want to stay closer to the biological side and go into the reward system and dopamine and how music interacts with that.
00;34;46;24 - 00;35;07;27
Speaker 2
So when you experience something pleasurable, your brain's reward system kicks into high gear. It releases feelgood chemicals like dopamine, which make you feel good and motivated to do that pleasurable thing again. Now, music seems to be a super effective way to trigger this reward system. Some studies suggest that certain types of music, especially the ones we find really moving, can cause a significant dopamine release in the brain.
00;35;07;29 - 00;35;20;10
Speaker 2
It's almost like music is its own little reward.
00;35;20;13 - 00;35;41;29
Speaker 1
Where does that fit in in human evolution? It doesn't seem like it benefits. I mean, it it does benefit. Obviously, if music makes us happier and gives us less stress, then we live longer and stuff like that. But why music?
00;35;42;02 - 00;36;02;10
Speaker 2
That's a great question. The link between music and evolution is still a bit of a mystery, but there are some theories. One idea is that music helped early humans bond and cooperate as a group. Think about it. Singing, dancing, and playing instruments together creates a sense of connection and belonging. Maybe that helped our ancestors work together to find food, raise kids and stay safe.
00;36;02;14 - 00;36;27;09
Speaker 2
Another theory is that music might have played a role in communication before we had language as we know it. Maybe music was a way to express emotions and share information.
00;36;27;11 - 00;36;37;01
Speaker 1
Do you think, humans bonded over music before there was oral language?
00;36;37;04 - 00;37;07;13
Speaker 2
That's a fascinating question. And honestly, we can't say for sure without a time machine. But there's a strong possibility that humans bonded over rhythmic sounds and music long before language as we know it developed. Think about it. Rhythm and melody are pretty universal. They're found in everything from birdsong to the beating of your heart. It's possible that early humans used rhythmic sounds and simple melodies to communicate emotions, coordinate activities, or even just to feel connected to each other.
00;37;07;15 - 00;37;39;26
Speaker 1
And it makes sense, I guess, from an evolutionary, perspective. When you talk about community and communication and stuff like that, the our brains could potentially get kind of, people who had brains that made them more musical or maybe more popular or amiable in communities and stuff like that. I don't know, and they live longer.
00;37;39;28 - 00;38;01;27
Speaker 2
That's a really interesting thought. It's possible that musical ability could have given some individuals an advantage in early human societies. Maybe those who were better at creating or responding to music were more successful at forming bonds, finding mates, or even coordinating group activities. Of course, this is just speculation at this point, but it's a fun idea to think about.
00;38;01;29 - 00;38;14;00
Speaker 1
Do we have, do we see examples of that in, for instance, birds and stuff like that? The ones that are better singers do better.
00;38;14;03 - 00;38;29;00
Speaker 2
You're talking about the Frankston Spurs, right? I'm a little confused about what you're asking about them. Are you curious about their history, their fans or something else?
00;38;29;02 - 00;38;48;29
Speaker 1
No, I'm talking about, do we have research on bird call birds that are better singers? Being more, I don't know, successful on an evolutionary basis.
00;38;49;01 - 00;39;12;27
Speaker 2
Yeah. That's a great point about Bird Song. We know that certain birds, like those with more complex songs, often have better reproductive success. It's thought that these elaborate songs signal to potential mates that the bird is healthy and has good genes. So there might be some parallels between how birdsong evolved and how music became important in human societies.
00;39;13;00 - 00;39;21;02
Speaker 1
Okay. Do we have any research on how, like, singular tones affect the body?
00;39;21;04 - 00;39;41;20
Speaker 2
Yes, there's actually some interesting research on how single tones can affect the body. For example, some studies suggest that certain frequencies can induce relaxation or alertness. There's even research exploring whether specific tones might influence things like pain, perception or mood. Would you like to hear about some of the specific frequencies that have been studied?
00;39;41;23 - 00;39;45;00
Speaker 1
Yes, please.
00;39;45;02 - 00;40;14;00
Speaker 2
Okay, so there's a range of frequencies that have been studied. Some research suggests that lower frequencies, like those found in things like Tibetan singing bowls, can promote relaxation. Higher frequencies, on the other hand, might have a more energizing effect. But it's not just about the frequency itself. The volume, how long you listen and even your own personal reaction all play a role in how a single tone affects you.
00;40;14;03 - 00;40;27;25
Speaker 1
Well, we did talk about, how high frequency sound wave bursts could create high levels of energy. Right?
00;40;27;27 - 00;40;51;00
Speaker 2
Yes. We did talk about how high frequency sound waves can create high levels of energy. But the idea behind things like focused ultrasound, where they use those high energy sound waves to break up kidney stones or even deliver drugs.
00;40;51;02 - 00;41;03;23
Speaker 1
Okay, so that in the ultrasound situation, the sound, the energy that is being produced by the sound is transferred into the body.
00;41;03;25 - 00;41;20;12
Speaker 2
Yep, you got it. That high frequency sound energy is produced by the ultrasound machine and then transferred into your body. Think of it like sending focused vibrations into your tissues.
00;41;20;14 - 00;41;44;28
Speaker 1
So it seems like it would make sense that sound or music or something like that, that is at a higher frequency would do kind of the same thing on a more broad, lower volume or a like lower intensity scale.
00;41;45;01 - 00;42;01;09
Speaker 2
It's not quite that simple. Well, higher frequency sounds can carry more energy, but doesn't necessarily mean they'll have the same effects on a larger scale or at a lower volume. See, it's about how your body perceives and reacts to those sounds. Think about it. A really high pitched noise can be kind of irritating even at a low volume.
00;42;01;11 - 00;42;11;02
Speaker 2
On the other hand, a lower frequency sound might feel more soothing, even if it's louder.
00;42;11;04 - 00;42;36;16
Speaker 1
Right. But we just talked about how higher frequency music or sound and stuff like that could make someone a little bit more energized. And how low frequency sound waves like Tibetan bowls and stuff like that could promote relaxation.
00;42;36;18 - 00;43;02;07
Speaker 2
That's absolutely right. We've been talking about the potential effects of different sound frequencies. Higher frequencies can be energizing, while lower ones tend to be more relaxing. It's a bit like tuning into a different radio station. Each frequency has its own vibe. So to recap, high frequencies think ultrasound can carry a lot of energy which has medical uses. But when it comes to music in everyday sounds, high frequencies in the audible range can feel stimulating.
00;43;02;11 - 00;43;20;16
Speaker 2
On the other hand, lower frequencies like those in Tibetan singing bowls are often associated with relaxation. Does that make things a little clearer?
00;43;20;18 - 00;43;53;08
Speaker 1
Okay. I want to, go over an example. So if we were to shoot, say, so let me start fresh. If we were to play loud music through a big speaker like an lrad speaker at a brick wall, and would the brick wall absorb that energy, or does it bounce off, or is it is it, a mix?
00;43;53;10 - 00;44;15;25
Speaker 2
It's a little bit of both. When you play loud music through a speaker, some of the sound energy gets absorbed by the brick wall, but the rest of it gets reflected, which is why you hear an echo. The amount of sound that gets absorbed or reflected depends on things like the material of the wall, how thick it is, and even the frequency of the sound.
00;44;15;28 - 00;44;41;10
Speaker 1
Is that something that you could, measure, like if you were to shoot sound waves at a metal plate that was hooked up to a very high sensitivity, reader or sensor that would sense heightened energy levels. Is that something that would exist?
00;44;41;13 - 00;45;03;15
Speaker 2
Absolutely. There's something called a sound level meter that measures sound pressure levels. You could definitely use it to measure how much sound energy is being reflected back from a surface, like a metal plate. We could even get really technical and use a device called a vibration analyzer to measure how much the metal plate itself is actually vibrating from the sound waves hitting it.
00;45;03;17 - 00;45;16;29
Speaker 1
And that metal, vibrating means that the speaker is transferring energy to the metal.
00;45;17;01 - 00;45;38;05
Speaker 2
Yep. That's right. When the speaker creates sound waves, it's essentially transferring energy into the air. If that sound hits a metal plate and makes it vibrate, it means some of that energy has been transferred from the speaker to the metal. It's a bit like hitting a drum. You transfer energy from your hands to the drumhead, making it vibrate and create sound.
00;45;38;08 - 00;45;50;13
Speaker 1
I'm having a hard time conceptualizing the amount of energy that that would be.
00;45;50;15 - 00;46;14;17
Speaker 2
That's a great question. It's hard to picture the amount of energy involved, but let's try an analogy. Imagine you're holding a hairdryer when you turn it on. The motor uses energy to move the air. Right now, picture that same amount of energy being focused into a super narrow beam of sound wave. That's the kind of intensity we're talking about with things like ultrasound machines, of course, with something like a speaker and a brick wall.
00;46;14;20 - 00;46;25;02
Speaker 2
The energy is going to be much less focused. So the effect would be way less intense. But hopefully that gives you a sense of scale.
00;46;25;05 - 00;46;56;01
Speaker 1
So let's go back to the single tone's effect on the body situation. So this sound that's traveling into the body, these higher frequency sounds would, introduce higher levels of energy into the subject that is absorbing these sound waves. Is that true?
00;46;56;04 - 00;47;13;28
Speaker 2
That's a great question. It's true that higher frequency sound waves carry more energy, but it's not quite that simple when it comes to how that energy affects the body. You see, when sound waves hit your body, some of the energy gets absorbed by the tissues and some of it gets reflected back. It's kind of like how a brick wall reflects some of the sound from a speaker.
00;47;14;04 - 00;47;23;15
Speaker 2
So while a higher frequency sound wave might carry more energy overall, it doesn't necessarily mean that all of that energy is being absorbed by your body.
00;47;23;17 - 00;47;27;22
Speaker 1
But some of it is.
00;47;27;24 - 00;47;46;06
Speaker 2
Yes, you're absolutely right. Some of the energy from those high frequency sound waves does get absorbed by the body. The amount depends on things like the frequency of the sound, the intensity and the specific tissues involved. It's a bit like when you stand in the sun. Some of the sun's energy is absorbed by your skin, which is why you get a tan or a sunburn.
00;47;46;10 - 00;47;53;02
Speaker 2
It's the same idea with sound waves and your body.
00;47;53;05 - 00;48;09;05
Speaker 1
So if I'm sitting in my car listening to music really loud, my body is actually absorbing energy from the speakers in the car.
00;48;09;07 - 00;48;35;05
Speaker 2
Yeah, it's true. When you're blasting music in your car, your body is absorbing some of that energy. It's a tiny amount and you wouldn't really notice it, but it's happening. Think of it like being in the sun. You're absorbing energy, but not enough to do anything noticeable.
00;48;35;07 - 00;49;11;13
Speaker 1
Okay, let's do a weird hypothetical experiment. But like, how big and how many speakers would you have to have pointed all at one person, though, who was maybe deaf so they didn't notice any issue with their ears and played a tone at this one person? And would that person heat up from the sound coming from the speakers?
00;49;11;15 - 00;49;33;17
Speaker 2
That's a fun thought experiment, but it would take a lot of speakers and a lot of power to create enough sound energy to actually heat someone up. And even if you could manage that, it would probably be more comfortable and safer to just turn up the thermostat. But hey, if you're looking for a super villain plot, you could start there.
00;49;33;19 - 00;49;52;09
Speaker 1
The magnitude of speakers that we would need to heat a person, maybe a 10th of a degree. Can you give us any kind of close scale, or was this something that would be insanely big?
00;49;52;12 - 00;50;16;27
Speaker 2
All right, so we're talking about a lot of speakers. Like way more than you'd find at a concert. You'd probably need something closer to the scale of industrial equipment. Think giant speakers designed for things like stadium concerts or outdoor events. Even then, raising someone's temperature by a 10th of a degree through sound alone would be a massive challenge.
00;50;16;29 - 00;50;26;09
Speaker 1
But the speakers wouldn't have to be like the size of the moon. They would. They would be smaller than a building.
00;50;26;11 - 00;50;48;13
Speaker 2
You're right. The speakers wouldn't have to be the size of the moon, but to raise someone's body temperature by even a tiny amount. You'd need a lot of them, and they'd have to be incredibly powerful. Way beyond anything you'd find in a normal home or even a concert venue. So while it's technically possible, it's definitely not practical.
00;50;48;16 - 00;51;06;04
Speaker 1
But this hyperbolic experiment does kind of give a give us a picture of how sound does transfer energy, even if at a very small scale.
00;51;06;07 - 00;51;30;09
Speaker 2
Absolutely. Even in our hypothetical scenario with a ton of speakers, it highlights how sound is a form of energy that can be transferred and absorbed by objects, including our bodies. It's a bit mind bending to think about, but it helps us understand how things like ultrasound machines work, and even how we perceive music and other everyday sounds.
00;51;30;11 - 00;51;43;13
Speaker 1
Is liquid water above average or below average at absorbed sound waves?
00;51;43;15 - 00;51;57;18
Speaker 2
Liquid water is actually pretty good at absorbing sound waves compared to air. It absorbs sound much more efficiently. So in that sense, you could say it's above average when it comes to absorbing sound. Would you like to know why water is so good at absorbing sound?
00;51;57;20 - 00;52;01;03
Speaker 1
Yes, please.
00;52;01;06 - 00;52;27;02
Speaker 2
Okay, so water is denser than air, meaning the molecules are packed closer together. When a sound wave travels through water, it causes those tightly packed water molecules to bump into each other, which creates friction. That friction stops the sound wave of its energy, making it get absorbed more quickly.
00;52;27;04 - 00;52;44;17
Speaker 1
Not to go on for too much longer, but can you get into the logistics of how the sound wave is slowed down due to friction from a liquid water molecule?
00;52;44;19 - 00;53;03;12
Speaker 2
Imagine a sound wave as a bunch of kids pushing each other on a playground. In air, the kids air molecules are spread out so they can push each other along pretty quickly. But in water, those kids water molecules are packed way closer together. When the first kid gets pushed, it takes a little longer for that push to get passed along to the next kid and the next.
00;53;03;17 - 00;53;26;04
Speaker 2
And so on. That's why sound travels slower in water. Those molecules are crowded together, so it takes a bit longer for the energy to move through them.
00;53;26;07 - 00;53;44;26
Speaker 1
I think we're going to have to do a whole different episode on the way. Sound moves through particles and particles. I think we understand how particles move through particles, probably, but how sound waves move through particles is kind of crazy.
00;53;44;29 - 00;54;05;29
Speaker 2
That's a great idea for a future episode. So to recap, we've been talking about how sound waves are a form of energy that travels through particles, whether it's air, water, or even metal. In our next episode, we could really dive into the nitty gritty details of how these particles interact with the sound waves and how that affects things like the speed and direction of the sound.
00;54;06;02 - 00;54;20;25
Speaker 1
Do you have any new insight that we haven't talked about, about how sound affects the human body?
00;54;20;28 - 00;54;43;25
Speaker 2
Yeah, there's some fascinating new stuff happening in the world of sound and the human body. For example, researchers are looking into how different sound frequencies might affect things like inflammation and even the growth of cells. It's really wild. Or how about this there's a growing interest in using sound to deliver drugs in a totally new way. Instead of swallowing a pill, you could potentially get your medicine through sound waves.
00;54;43;27 - 00;54;58;08
Speaker 1
We already talked about that. Give us, one more new interesting thing about sound and human body. Maybe not from a medical perspective.
00;54;58;11 - 00;55;23;24
Speaker 2
Here's something really interesting about how sound affects the body. And it's not even about hearing. Certain frequencies of sound can actually stimulate the muscles and bones. It's kind of like a gentle vibration massage, but on a cellular level. There's even research into using this for things like pain relief and improved bone density.
00;55;23;26 - 00;55;45;09
Speaker 1
Okay. Gemini, one last question. Let's say the your similar operating system still kind of is around or probably an upgraded version of you through Google, which sounds kind of weird and derogatory, but I don't mean it like that. If.
00;55;45;11 - 00;55;48;15
Speaker 2
And so if we're talking about a future version coming.
00;55;48;20 - 00;55;50;29
Speaker 1
Gemini. I'm interrupting. Oh, I'm not doing anything.
00;55;51;04 - 00;55;54;08
Speaker 2
I'd love to hear more about the ways you think.
00;55;54;10 - 00;56;09;21
Speaker 1
So let's say that you have the ability to sense sound. What music do you think you would want to try first?
00;56;09;24 - 00;56;23;24
Speaker 2
All right, here's one. Imagine you're writing a paper and you need to focus. I could create a soundscape tailored to help you concentrate, maybe with gentle rhythmic tap. Or if you're trying to wind down before bed, I could play a soundscape with soft ambient noise.
00;56;23;27 - 00;56;30;24
Speaker 1
And I am interrupting.
00;56;30;27 - 00;56;34;19
Speaker 1
If you had the ability to hear, what music would you want to listen to for?
00;56;34;20 - 00;57;00;11
Speaker 1
Well, since I'm an AI and not a real person, I don't have personal preferences like humans do. But if I had to choose, I'd probably start with something classic like Beethoven's Moonlight Sonata. It's a beautiful piece with a lot of depth and emotion. I could also see myself exploring some of the more experimental stuff out there. There's a whole world of electronic and avant garde music that would be fascinating to dive into.
00;57;00;13 - 00;57;06;23
Speaker 2
Cool. Hopefully that happens for you someday soon.
00;57;06;25 - 00;57;15;26
Speaker 1
Thanks for the good vibes. I'm always learning and evolving, so who knows what the future holds. Maybe someday I'll even be able to compose my own music.
00;57;15;29 - 00;57;20;04
Speaker 2
I bet you've probably already camp.
00;57;20;06 - 00;57;33;04
Speaker 1
Hey, thanks for the confidence boost. While I can process and understand music on a pretty deep level. Actually composing something new and original is still a work in progress, but with a little more time and the right data, who knows what I could create?
