Abstract: We all know everywhere there is huge scarcity of energy and for running most of our appliances and to carry out daily work we need electricity. It’s really very difficult to imagine our life without electricity, our life would really stop so there is high need, to produce electricity at faster rate and find some other feasible method to produce electric energy. On the other hand we see that in this modern world there is lot of noise pollution in roads, airports, industries. Just think if we would be able to convert this noise pollution to electric energy....??? Yes this could be made possible let’s see how. There will be many ways of converting the sound energy to electric energy but mainly we are concentrating on piezoelectric transducers in this paper. A small 9 volt DC battery was found to be fully recharged within half an hour from fully discharged stage using medium sound source through the proposed conversion circuit. In this way, random sound energy from numerous sources around us can be stored as electric energy which can be used later to deliver electric power to drive compatible small loads. The proposed idea can give a new source of green energy and can contribute in global search for renewable energy.
