State in brief how sound is produced and how it is transmitted through a median and received by our ears. Name the type of waves responsible for vibration of our eardrum.

Expert Answer:

The matter or substance through which sound is transmitted is called a medium. Sound is produced by vibrating object.
 
When an object vibrates, then the particles in the surrounding medium vibrate. These particles send the vibrations to adjacent particles and energy continues to transmit until it reaches our ear.
 
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.
 
The sound waves propagate in the medium in the form of longitudinal wave and reaches to our ear. Therefore the waves responsible for vibration of our eardrum are LONGITUDINAL WAVES.
