When an object vibrates, the particles in the surrounding medium vibrate. These particles send the vibrations to adjacent particles and energy continues to transmit until it reaches our ears.A wave is a disturbance moving through a medium when the particles of a medium set the adjacent particles into vibration.The particles do not move forward, but the disturbance does.When these vibrations reaches our ears, the ears allow us to convert pressure variations in the air with audible frequencies into electric signals that travel through the brain via the auditory nerves.

Consider a bell. When the bell rangs what happens!!!!, the bell vibrates in small amount and that vibration collides with the surrounding layer of particles and this particles too vibrate in the form of back and for motion as we know that the sound wave are longitudnal wave. That vibrating particles collides with another layer of particle and this happens continously and reaches at a layer of the ear of a person is standing. As, by this vibration our eardum vibrates and it goes to the brain and this how we hear the sound
