sort of a microphone system, i guess. convert sound to electrical energy, especially in traffic congested areas.instead of wasting the sound produced, why not use it to generate electricity?

Certainly a microphone converts sound energy to electricity. But sound contains a very feeble amount of energy. THis would certainly not be a practical means of generating useful quanities of energy. Sound simply doesn't have enough energy to be a viable economic source..

While they haven't found a way to generate electricity through sound, they have found ways to use sound waves for other things, such as refrigeration. Ben and Jerry's (the ice cream guys) had a research project going on with Penn State University wherein a thermoacoustic refrigeration system was designed and built.

The "law" of energy conversion states that only about 10% will convert cleanly to energy. The rest would be lost to fiction, heat, mechanical, and conductive loss.

Great thought though, it's just that the physics aren't there (yet).

There isn't a lot of energy in sound waves. Also it's hard to imagine a conversion system which wouldn't waste most of the energy. It's theoretically possible, but I doubt it would ever be practical.

no... current technology isn't good enough to do that...
Sound is "mechanical motion" of air...
The energy produced by a microphone... (through induction) is in the tenths of milivolts. They are only USEFUL, because of the PREAMP then AMP.
It's a good idea... but even 1,000,000 decibles of moving a diaphram... would result is way less then solar energy.

Of course your Idea was very good,
For the research is going on in this world,
May be shortly within a few years we may use in our daily life.

I think it's a great idea, i don't know exactly how to do it, i just have an idea, maybe somebody knows, i would have to woork on
it. Don't ever surrender, good ideas need lot of woork to make them reality.

might be
we can convert the pressure variations (sound) into electric signals using very sensitive piezo-electric crystals

sure why not? People do it all the time.
