Question

Explain how the eardrum helps them to hear

Answer 1

Answer:

Sound waves travel into the ear canal until they reach the eardrum. The eardrum passes the vibrations through the middle ear bones or ossicles into the inner ear. The inner ear is shaped like a snail and is also called the cochlea. Inside the cochlea, there are thousands of tiny hair cells. Hair cells change the vibrations into electrical signals that are sent to the brain through the hearing nerve. The brain tells you that you are hearing a sound and what that sound is.

Hope this Answer help you.

Answer 2

Answer:The Ear Drums Receive the sound Vibrations From It’s Surroundings and the Vibrations Go further Through the Cochlea{a Hollow Bone} which helps to perceive the sound and hence we can hear it..
