Question about sound energy?

Question

Hello I'm currently working on physics project about physics of sound.

There are some questions however.

Are there any occasion or examples that sound energy turns into other form of energy such as heat? or electronic?

Thank you !

Answer 1

After any sound dies down to the point where it's "gone"--that energy has gone to heat. A common conversion from sound to electricity occurs in a microphone, usually using some movable diaphragm attached to a magnet with pick up coils which have an induced EMF caused by the varying magnetic field of the moving magnet.

Answer 2

What is the Sound? The sound is energy that appears in the vibration of atoms and molecules. And what is the Heat? its mechanism is similar to sound, with the difference that in sound, energy jump from one atom to the other but in heat this energy goes nowhere(we assume our system is closed)!
You can do the interesting experiment that these two kinds of energy transfer to each other :
first prepare a glass of water then take a nail with a tongs and heat it on fire that its color becomes red, then immediately insert the nail into the water. Now you can hear the sound like "jiiiiing" from the glass. it resembles that the glass is screaming. Furthermore if the nail was bigger you can sense the vibration from the tongs. this experiment shows that the atoms on the surface of the nail have enormous energy than molecules of water, this energy propagate through water and reach to the glass and shake it. I do this experiment many times. but watch out.

some kind of Crystals can transfer vibration of atoms and molecules to electric shock, called piezoelectric. you can find more and interesting information on : http://en.wikipedia.org/wiki/Piezoelectric
