CBSE Science Fair Exhibition Project, “Conversion of Sound Energy into Electrical Energy” Theme “Energy Resource & Conservation” for Class 9, Class 10 and 12

Project Name : Conversion of Sound Energy into Electrical Energy


Theme Name : Energy Resource & Conservation



In the model, the sound produced by vehicles, vibrate a diaphragm placed beside the roads. When the diaphragm vibrates, it makes a solenoid coil move, which is attached to it. When the solenoid coil vibrates it changes the magnetic flux around it, due to which induced
current is produced by the process of electro-magnetic induction (Faraday‟s law of induction).

The two ends of the solenoid coil are connected to a galvanometer, which shows deflection due to the production of the induced current in the coil. This small induced current is amplified using an amplifier and the amplified low voltage current is converted into high voltage current by a step-up transformer.

In India, there are 80,000 villages where electricity is still a dream! India is called a developing country, and a major part of our country has no access to electricity. So if we want our nation to progress, the most important aspect we have to focus on is the production of electricity. In India, the noise produced on the roads in the metropolitan cities is
considered a curse; but if this curse can be changed into a boon .i.e. by changing the noise pollution into electrical energy, our country can become the most prosperous and developed nation. This project is suitable for India because of its ever increasing population which results in ever increasing noise pollution.
