Question

how can we hear with our ears (ans the following question)​

Answer 1

Answer:

our body changes the sound energy into nerve impulses which are then interpreted by our brain. Each hair cell consists of small stereocilia attached at the top of it. Sound moves the stereocilia back and forth. Stereocilia can be bent or broken if the sound detected is loud. This may lead to dead hair cells due to which no more sound can be transferred to the brain

Answer 2

Answer:

Sound waves enter the outer ear and travel through a narrow passageway called the ear canal which leads to the eardrum.

The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear . These bones are called the malleus ,incus and stapes
