Question

Match the descriptions of the stages of the act of hearing with the correct stage order.

Answer 1

Answer and Explanation:

Working of ear is follows:

Stage 1 : Firstly, the ear collects compression waves from the surroundings.

These waves are collected by the outer ear and passes to the eardrum via the ear canal.

Stage 2 : The ear amplifies the compression waves when the waves enter the ear drum. It caused fluid in the inner ear for moving.

Stage 3 : The amplified waves stimulate the hair cells of the ear through the fluid in the inner ear. It causes hair cells to bend.

Stage 4 : The hair cells transmit nerve impulse to the brain by changing movement into electrical impulse.

Stage 5 : The brain interprets the nerve impulses as sound.

Stage 1 - The ear collects compression waves.
Stage 2 - The ear amplifies the compression waves.
Stage 3 - The amplified waves stimulate the hair cells of the ear.
Stage 4 - The hair cells transmit nerve impulses to the brain
