Mechanism of Hearing: Anatomy, FAQs

Definition Of Hearing

The mechanism of hearing is one of the complex processes by which the sound waves get converted into electrical signals that the brain interprets as sound. This process forms the basis of communication and environmental awareness.

Collection Of Sound Wave:

Hearing initiates by collecting sound waves through the outer ear.

Outer Ear:

Pinna collects the sound wave and leads it into the ear canal.

Transmission Of Sound Waves :

It is responsible for pressure wave transmissions and amplifies the pressure waves in the air.

Middle Ear

The eardrum vibrates with the arrival of sound waves. The vibrations then get passed on to the ossicles.

Change In Sound Wave:

In the inner ear, the sound waves get changed into electrical signals.

Inner Ear

The cochlea has hair cells that turn the vibration of the sound into a nerve impulse.

State Of Passage To The Brain:

These nerve impulses are then passed on to the brain, which interprets them.

Auditory Nerve:

It carries the electrical impulses from the cochlea to the brain.
