Answer

The human ear has 3 parts-

  1. Outer Ear - It collects sound from surroundings
  2. Middle Ear - It amplifies the vibrations
  3. Inner Ear- It converts sound into electrical signals

 

The outer ear called pinna collects sound from the surroundings.

The collected sound passes through auditory canal.

At the end of the auditory call, there is a thin membrane called the eardrum

 

When the sound reaches the eardrum, it vibrates due to rapid compressions and rarefactions.

The vibrations are amplified by the three bones present in the middle ear.

This sound is transmitted to the inner ear.

 

The inner ear converts sound into electric signals

These electric signals are sent to the brain and the brain interprets these signals as sound.
