A small baby recognize his/her parents from their sounds and responds to it. Thus, we can say that sound is a form of energy which produce a sensation of hearing.

Sound is produced whenever we speak, or whenever we strikes something with the help of hard objects. In each case the sound is produced due to vibration in the medium.

Whenever it is strike against a rubber pad cause the prong to start vibration and these vibration produces sound..
