Question

Explain how human beings hear sounds.​

Answer 1

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.

Answer 2

Answer:

The sound wave passes through the ear canal to thin and stretched membrane called eardrum or tympanum. The ear drum vibrates and produces vibrations. The vibrations are amplified by the three bones of the middle ear called hammer, anvil and stirrup.
