Question

How does the sound produced by a vibrating object in a medium reach your ear?

Answer 1

Sound is produced by vibrating objects. When an object vibrates, it sets the particles of the medium around it vibrating. The particles do not travel all the way from the vibrating object in the ear. A particle of the medium in contact with the vibrating objects is first displaced from its equilibrium position.

It then exerts a force on the adjacent particle. As a result of which the adjacent particle. As a result of which the adjacent particle get displaced from its position at rest. After displacing the particle comes back to its original position. This process continues in the medium in the sound reaches our ears.
