....... Is there a feasible method to use, to convert sound energy to electrical energy.

Yes. I heard of a research that lets you charge your phone when you shout into it.

The logic is that VIBRATION of the waves are used to activate sensitive electronic components (dunno any for now). Just like when you walk, the oscillating movement of your feet can be converter to rotary motion needed to generate electricity (read on Electricity generating shoes/sneakers).


The human sound produces around 87-88 dB (thanks to teempakguy). This, relative to amount of electricity needed is like saying you need a straw to siphon the ocean.


But with booster circuit, we can generate reasonable amount of electricity. Say 12W/ 20V(dunno if such circuit exists, but sure I/We could make one). Sure, DC could be genetated from this, which if at all makes sense like say 20V would need to be inverted into AC. This proves its not worth it afterall since batteries & solar can produce such & then inverted into AC considering the factor of pollution Noises causes.


Yes, we can. Am sure but its not appreciable & the it causes pollution.
So to fully answer your question :

"NO, ITS NOT FEASIBLE FOR NOW"

Sound energy . . . to electricity . . . er . . . well, a piezoelectric array, connected to a super capacitor can do the trick. Although, producing electricity from sound is rather difficult. Because it cannot be made to behave like a particle.

common how does the microphone work, the vibrations from the sound is converted to a coil changing its distance from an underlying magnet, and you know what this produces voltage induced in the coil, then this low current allows a higer current to flow through the collector of a transistor(Amplification) basically.

Nice one teempakguy
piezoelectric devices can do the trick, but electgineer where can we get large and continuous sound to generate enough electricity..... i doubt if you can accommodate such a noise.
