In the present era, there is huge scarcity of energy and to carry out the daily activities, electricity is the major requirement. There is a need to produce electricity at a faster rate. In the basic applications, sound is converted into electrical signals to travel over the media for communication purposes. The application of sound energy as electrical energy can be much beneficial. It can be used to lighten the street lights by using the noise made by vehicles. This technology can also be used in industries, airports, runways. Conversion of sound energy into electrical energy appears to be one of the promising techniques to increase the production of energy without depleting natural resources. The objective of this work is to create a device that can convert the sound energy into electrical energy and harvest it for future need. Huge amount of noise is created in the surrounding by different means and this noise energy is generally let into the atmosphere which is not utilized and goes wasted. This work also describes the use of this conversion method in the surrounding to harvest energy from the vehicular noise, noise created by humans and industrial noise. By doing so, there is a reduction in pollution as well as the efficiency of the machines is increased. In today's world, a suitable method of power generation is required which could benefit the society. Thus, the concept of conversion of sound energy into electrical energy have been well discussed. Various applications based on the conversion have also been highlighted.
