Question

Mention the conditions for sound to be heard?

Answer 1

There are three conditions for a sound to be heard:-

1. There must be a vibrating body that should be capable of transferring its energy to its surroundings.
2. There must be a material medium to pick up energy and then propagate it in a forwarding direction.
3. There must be a receiver, so as to receive the sound vibration and then transmit it to the brain for final interpretation.
