What would a person hear, if he moves away from a source of sound with the speed of sound?

Text Solution

Verified by Experts

The person would be hearing nothinf if he is moving away from the source with the speed of sound. It is so, because the relative velocity of sound waves with respect to person is zero. Therefore, the sound waves cannot strike the drum of the person's ears and hence no sensation of hearing is produced.
