Generation of Usable Energy from Unwanted Sound

Life is intricately woven with many necessities. One such essential need of life is electrical energy. We are all aware about the load sheds and power cut which is all due to the scarcity of electrical energy. The fast moving pace of life would slow down drastically without generation of adequate amount of electrical energy. On the other side of the scenario the world is everywhere facing noise pollution in abundance. If we can ‘non -technically’ define what sound energy is, we would say it is the most neglected form of energy which is only considered to be a wastage. The theorem of energy conservation very well states that Energy can neither be created nor be destroyed; it can be converted from one form to another. So noise being one form of energy cannot be destroyed for reducing pollution but surely can be transformed into another form of energy. Here arises the idea of generating usable energy from unwanted sound, and this usable energy could be in the form of electrical energy.
