Sounds that animals make can be really different, and it turns out that there's a reason why some species communicate with certain sounds.

If sound waves realese energy as heat, how many people screaming at an egg would it take to fry it?

[@romajimamulo]

More than could fit around an egg.

[@voidnerdvs7660]

What about ‘how many frogs’...

[@jeremydavis3631]

Hm... The waves would interfere with each other, which I imagine would reduce their effectiveness at heating the egg as compared to just summing their individual heat outputs. It might be barely possible with a single really loud ultrasonic speaker placed right next to the egg, but it seems unlikely. Or maybe multiple speakers with care taken to ensure they're all in phase with each other so the waves interfere constructively at the egg. It sounds like an amusing experiment, even if it gets no results. :)

[@Bl4ckDrg0n]

This is something very nice you can tell to someone who believes 5G causes coronavirus or cancer lol

[@fighteer1]

I have to think that the energy of the sound waves striking the egg would crush it long before their attenuation heat loss would even be measurable on that small a scale.

[@Caron_]

You know how they always do a pun in the last line, right? This time it was an auditory one because I am pretty sure it was intentional that "the right ear" in the last sentence mostly came from the right side of my headset. Wouldn't have noticed it without it. That is so next level.

[@falahati]

Instead of describing it as the speed in which you can hear it, you could have explained it easier by the "penetration potential". A low-frequency wave is better at penetrating and traveling through a medium (in this case, the air). This is why you can bang your hand on the table and it makes a loud sound but not speak through it as efficiently. High-frequency wave, however, tends to reflect easier instead of penetrating the medium.
