The intensity of sound of the drip thawing snow is only 10^ (-14) watt / cm^2.
that of a low conversation at a distance of 5m is 10^(-12) watt / cm^2.
that of a Symphonic orchestra is 10^(-8) watt / cm^2.
that of airplane engine at a distance of 5m is 10^(-4) watt / cm^2.
This will give an idea of how much energy we will get if sound energy is converted into electrical energy.
The microphone or simply, a moving coil in a magnet can convert sound to electrical energy.
Only a small amount of energy is got by this conversion.
This small electrical energy controls large powers.

The microphone converts sound energy to electrical energy.....scientists are now trying to convert the noise pollution into electrical energy!!!

Sound power may be switched over into almost the different variety or power (apart from nuclear power). besides the indisputable fact that, air isn't an excellent transmitter of power and recuperating power from noise polution does not be very achievable. The loudest recorded noise (that I have study) replaced into the blast from a Saturn rocket at Cape Canaveral, Florida. The sound waves (rarefactions and condensations) varried from close to vacuum to 2 times(?) atmospheric pressure. you need to harness such huge sound pressure yet does not favor to be everywhere close to it. I also study that a Frenchman(?) invented a large compressor-pushed police whistle just about as massive as a motor vehicle that generated a noise so low in frequency that he ought to not listen it besides the indisputable fact that it grew to change into his insides into jelly from the vibrations. also even although a huge symphony orchestra can artwork up a sweat perchance taking section in allegro FFF! they basically impart some watts of power to the air interior the live performance hall. so that you're superb perfect in concept yet ought to extremely come across a extra efficient (and safer?) technique of acquiring power. good success.

Microphone, telephone
Heat energy (of your body (food)) → Chemical energy (body) → Mechanical energy → sound energy → electrical energy

Microphone
Sound creates vibrations in the diaphragm placed in a magnetic field.This in turn creates Electricity.
The reverse process is used in the loudspeaker.

of course!!!!!!!!! using a microphone. it converts sound energy, amplifies it, into electrical energy . we hear the sound in loudspeakers.

yes,
vibrations can move a coil in a magnetic field causing induced current
