Can Loud Sounds Actually Cook Things? The Sound to Heat Experiment
Vložit
- čas přidán 10. 06. 2024
- In this experiment I test out if you can heat things up with sound waves! I start off with low frequency 20 Hz and then turn up the frequency higher and higher to try to cook an egg just from sound! I talk about sound waves and how frequency is related to the energy of the wave.

You should note that the relative energy I showed assumed a constant amplitude, but that is obviously not the case across this whole experiment.
The Action Lab hey ! awesome videos dude ! but I have a doubt... u mentioned that cooking the egg could easily be done by putting it in the vacuum chamber... but how can u produce what's called 'Sound' when there is no media for it to travel (air is what I meant.. in vacuum.. no air).. because sound waves are longitudinal.. and thus require a media ! I know that the egg is touching the head of the ultrasound emitter. but what is it was not in contact ?? hope u reply !
I wonder if the thickness of the layer of egg, the speed of sound inside the egg, and the frequency all play a role. It would seem to me that if the frequency is so low that the bottom and the top of the egg layer "peak" and "valley" almost all together, you're not going to get a good pressure gradient, which might mean that the transition from ordered to disordered movement takes longer. I think that's why Cody wasn't able to fry ants in the microwave. Microwaves of course produce electromagnetic energy whereas speakers produce mechanical energy, but I think a reasonable analogy can be drawn between the two.
Anyway, I think that's part of the relationship between the frequency and the heating. It's not just that the higher frequencies carry more energy at a given amplitude, but the higher frequencies might also do a better job of creating disordered movement due to pressure gradients rippling through the material.
Bro please! Try it in a vacuum chamber, it's my birthday and is love to see it. I'm pretty sure other want to see that too! Your channel is absolutely dope! Keep up the good work :)

Probably one Karen would do. Maybe 2, just to be sure.
Sounds like the intro to a joke.
How many stand up comedians does it take to cook an egg by screaming at?
None, the eggs were part of the audience where they were thoroughly roasted.
It would take 1 year and 7 months of yelling at it 24/7 to increase it by 50 degrees. Of course, you would have to bundle all of that energy into a short period of time due to natural energy dissipation over time.

I did learn this in college. But today I understand what they were trying to teach 😂
Goes to show how bad teachers are... They couldn't get the job done :) They're mostly outdone by 10 minute videos.
Helbert Gascon couldn't agree more
Well for me it was something obvious from what i know sound is particle vibration and heat is movement of those particles pretty same right? Thats why i am here :D
This is why I refuse to go to college (among other things)
how much of the heat was from the electronics inside heating up?
intrested in this too, from the medical equipment, i think the inner components where heating up the metal plate a bit, which warmth got into the egg
It is obvious that the sound waves are not doing anything here to heat up the egg. A weak 10 deg is nothing. He should be taking temp reading on the gun itself also.... This vid is absolute BS
sk8pkl it aint completely bs, atleast, his theory aint in my oppinion.
Arent microwaves a kind of sound too?
i think BS is a little over the top but i do agree the experiment could do with some refining.

I've studied electrical and computer engineering and also a successful car audio SPL competitor achieving 155+dB in my car. I do agree that higher frequencies at the same amplitude equate to more energy in the system. But the amplitude is not the same as you increase frequency. The excursion on the diaphragm significantly decreases as the amplifier is not magically delivering more power. Actually the common trend in amplifiers is to deliver less power at higher frequencies. At best it would deliver the same power at all frequencies. What is actually more likely to produce heat is the low frequencies in this experiment as harmonics and impedance effects take over. Lower frequencies have effects closer to DC on the inductor, causing the coil to heat up the cone, where the egg is located. In my car, a 16Hz tone at about 10kW will heat the cones to the point where it is uncomfortable to touch within 5 minutes. At 40ishHz even at 15kW of power for 5 minutes, the cones will just barely warm up. I can assure there is no signal clipping involved. It all comes down to excursion and frequency leveling to the same overall power. The effects that take over are impedance and resonance in the inductor.
You are correct, my relative energy numbers were assuming constant amplitude which was not the case
:) no hate
I have most of an EE degree, but technically, I don't. My point is, one doesn't have to have a degree to know or understand engineering concepts. Engineering involves understanding math and science and materials (more math and science) as well as design. Plus, the guy didn't say he was an actual engineer. On a technical level, what was actually wrong with what he said in his post? That would be more helpful for all of us reading on here.
if it was constant amplitude that would be an ideal amplifier, especially if combined with a "constant amplitude" speaker, you would get an exact replication of the source material.

We need readings in Celsius!

I love this channel and all the crazy experiments! On this one, with the ultrasonic transducer, it seems like having the egg in contact with the device introduces some variables, versus if the egg were receiving the sound waves through air.

@@chriss8075 Really bro...
Funny how him moving his arm really fast makes him look hildish, althought he's 100x smarter than All of us. 😂
Might that transducer device just be getting warm due to its internal workings such as friction, electrical resistance etc…?
The device head is getting warm due to the ultrasonic waves themselves. When you have them connected to the body it’s able to dissipate the wave so it does not heat up
its heating the egg up at about 4 watts as he said in the video.
Yes and no. Peizo transducers like that are specifically tuned with an specific counter mass and driver frequency to conduct the most amount of energy into whatever medium they are supposed to be coupled with, human flesh in this device, water in humidifiers and jewelry cleaners. When you run them without a load they heat up because they can't couple that energy and the system can't run anywhere close to resonance. It's very much analagous to an electrical impedance matching transformer like you had to put on old TV's and on radio gear to match the impedance of the antenna or load you are putting the power into. If your impedance is mismatched the device isn't able to conduct that energy outwards and you get standing waves within the transmitter/feed/transducer. Each one of these standing waves is a node in which the energy is bouncing off itself. In a transducer this causes the power dissapation to greatly diminish and causes it to overheat because the peizo transducer is absorbing power rather than converting into sound that can be carried away.
What that means is the transducer itself is heating up not because of the sound it is emitting, but it's very nature as an electrical load. Yes, energy is conserved, 4 watts is 4 watts is 4 watts in electrical, or other energy forms but it's not really the sound doing the majority of the heating but rather the inability of the device to drive a load in it's designed efficiency range so it becomes more or less a resistive/reactive load.
Alan Tennant exactly.

Too bad your son never replied to you
Action lab is the best science channel. I love these experiments
Are you sure that the temperature increase was caused by the soundwaves?
It could also be caused by the heat of the copper inside of the speaker .
If there's way to convert heat to sound, it might be extremely important
How do you make sure the hearing is because of the sound and not because of the metal transducer heating due to electricity?
Edit: Also, when you mentioned about doing the experiment in vacuum, to avoid the loss of heat, don't you think there won't be any sound wave in the first place, because you're doing the experiment in vacuum?
First Last this was a great question, Sir!
It's sad that he never even alluded to the heating of the transducer. Even though piezoelectric transducers are very efficient, a lot of the electrical energy going in is converted to calorific energy = heating effect on the metal components.
I would like to see an unbroken egg in a ultrasonic cavitation cleaner, and see what happens to it. If the shell survives the cavitation (doubtful), I suspect that the locally induced heat would 'cook' the egg, even as the surrounding water carried the heat away.
I really love this channel! I learn and get entertained at the same time!
This is so king of random kind of videos , i like it ! keep it
The laser itself isn't measuring the temperature, the sensor below the laser does it. The further you're away the more inaccurate the measurement gets
Came here for this; IR thermometers actually measure the mean temperature inside a circle, who's center is the laser pointer. The circle's diameter gets bigger as you move away from the target. IR thermometers are plainly the wrong way to measure temperatures focused on a small area.

Actually the speaker cone will get heated up after long use so all the heat will not be from sound 2:42

But why
Too much ICE = BURN?
The burn you feel is your nervous system emitting/triggering heat production in the skin to counter the cooling effect t of the ice

Omg why did you even do this when you have a dog

A dog can’t hear 1 megahertz (They hear 40hz-40khz), and even if they could, our phones can’t produce that sound due to the Nyquist limit.
This should be trending!! that was very surprising to me because I am an Engineering major, and that was all very very very interesting.
Keep up the good work bro!
Thanks for the sound system test
Could you do a video explaining how "sound flashlights" work? Maybe how to make them, and what uses they can have?
It's like you point sound to a certain area and only if you are in a certain spot, you can hear the sound.

You have some really cool ideas for the video!
I love your videos! Continue what you do
Wouldnt putting the egg directly on the speaker result in kinetic energy cooking the egg if it did happen just like the mixing experiment you did?
i understand that temp is just an average kinetic energy of a given system aswell just before anyone comments
while some of the kinetic energy(albeit very low amounts due to small range of motion) is coming from the 'speaker' it is lost MUCH faster to the air. even a very small amount being introduced by the temp probe in contact with it as well(also negligible)
a better way to rule that out though, would to have the ultrasonic transducer sitting very close to the egg surface from above, while the egg is sitting on a material that is very insulated for heat transfer. you will lose some of the energy from the waves from the speaker to the inverse square with such a short wavelength, but would rule out some of the variables that this setup has(keeping in mind, that even these are almost nil for impacting results)
I think, what would happen if you put dry ice inside the vacuum chamber for some time.. Will it vanish...???
But dry ice don't melt... That's the fact
Ankit Gupta It just skips the liquid state right?
Dry ice directly converts into gas... Which is CO2... And when its in vaccum, it will be pulled out by the chamber because of the vacuum... So nothing should be left... As per my assumption.. 😅
Kasai Icarus yeah!!
Wooooow... awesome. Not. Also happens at room pressure
i love your channel so much dude
This was amazing, when the egg started to not move I was like "omg, that is a whole new level of what I thought would have happened" and also The Action Lab I just started watching you yesterday with the Strawberry and Bleach one then the Venus Fly trap, and I really enjoyed all the science terms and learning new things, you are awesome!!
Just by watching it I can see/hear that it really "Hertz"
That is an awful pun.
And it cracked me up. Thank you.
Hlo obito.
Use Kelvin or Celsius please, I dont know how many are 100 ° F without using maths :S
Edit: I mean, It would be easier to understand for those who are not from USA. In Europe we use Celsius in normal life and Kelvin in physics, chemist, etc.
you can just google it. 100 °F is almost 38°C
no lol
not only is farenheit not linear, its not used by scientists.
It's what we use to cook in the states, so for a "cooking video" it is probably more relevant to most of his viewers. I know it is really science, but...

Wow that seems interesting
1 view, 11 likes. CZcams is drunk or something
Wouldn't you think that the wire coil at the base of the speaker's diaphragm would add heat if you left it? How would you know if the ultrasonic thing didn't create its own heat as part of the therapy?
If the reverse of this is possible, heat into sound and ultra sonic pulse, that is also great youtube with applications.
Amazing video!
Hey I love the channel!! Just a tip: you should try to hook up your lav mic from the inside of your shirt or around the back, rather than in the center on the outside.
Just a small suggestion but regardless, I love your stuff and you def gained a new subscriber today:)

Ya gotta 'Mythbusters' it and take it to it's logical conclusion, actually cooking with sound!! Thanks for the video :)

But will it blend?
those blenders are a marketing lie
Blox117 which blenders??
blendtec
William Velez That is the question...
Love your channel mate! Please do a video on BOILING WATER WITH SOUND..... ☺️
thanks
This is agitation of the material, not unlike the blender boiling water. The driver also heats as the voice coil absorbs power. Try this again with stationary egg and blasting it sonic energy. It WILL require some expensive gear to produce the sound intensity required but its out there, ans as you know, its a really poor way to heat anything. What temperature does your ultrasound pad rise to with no stuff on it when operated over the same time period? Is that egg getting warm just from vibration or partially from conduction of heat from the pad? Fun thought experiments...
My thoughts exactly. Good suggestion though...
Jennifer WhiteWolf
You need to take into account that at lower frequencies, the speaker cone is able to move at a much larger range of motion. But as you increase the frequency into the thousands, the movements will decrease. Like, the speaker will still be moving, but the range of motion will be drastically reduced, which would reduce the output of energy from the speaker. If the speaker was moving the way it was at 40 hertz and maintained that up to 10,000 hertz, the energy required would be ridiculous. lmao
Of course, the range of motion of a speaker relative to its frequency depends on the quality and power of the speaker. Bluetooth speakers don't tend to be of the best quality, which is why in some cases, if you fail to hear higher frequencies, it isn't your hearing, but the speaker itself.
not really maybe only 16000 watts
you cant afford a bluetooth speaker in high quality cause it will cost when i would build it 1000000dollars
The speaker itself will also heat up due to electrical current flowing through its voice coil, which has a certain electrical resistance. Electricity will be converted to heat even if you would be supplying the speaker coil with direct current (which means a frequency of 0 Hz, hence no acoustic energy). I'm also pretty sure that a lot of the heat generated by the ultrasonic device comes from current going through less-than-superconducting materials.
DC would cause more heat than AC as well.
he always blows my mind
You should check out the ultrasound welding process. It’s pretty cool and along these lines :)

This type of Fequency generator app RIP'ed my phone speakers and some other circuit which made me replace my phone motherboard...lol...It proved costly to me. Thanks for the video.
Love the videos! I have an experiment that I'd love for you to try! Since our atmosphere is only 20% oxygen, would you be able to hold your breath longer by breathing in pure oxygen?
rman5001 no, because its not lack of oxygen that forces you to breath in/out. its the carbon dioxide which is created whilst you are holding your breath
Dills60//redpanda What if you breathed pure oxygen long enough to lower the CO2 in your blood? Would it work then?
Pure oxygen is dangerous for human.. More isint always good.
some professional breath holders do this to hold their breath longer underwater. Its not recommended because it could be dangerous. But if you know what youre doing it can be done. But it doesnt help that much anyway, were talking about maybe a few more seconds at best, however in competitions and breaking records a few seconds can be a whole lot.
rman5001 you cannot lower it because CO2 is the product of your tissues which take oxygen and give CO2 to the red blood cells, if you breathe in oxygen, it will be produced. Inhaling more oxygen would increase the oxygen level in your blood but it wont remove the excess CO2 (hypercapnia) which is what causes the sensors to set off and your blood's pH to fall.
remember that man that screamed into the egg?
well, it didn't boil...

I know you can weld plastic with ultrasonic waves in applications where you cant have too much heat so i think with the right type of food you might sort of be able to. But the effect will be negligible through the air, it would need to be direct or the heat and sound will disperse into the air
