Answers
Answer:
HAVE A GREAT DAY
Explanation:
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:
How does the human ear detect sound?
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. ... Hair cells near the wide end of the snail-shaped cochlea detect higher-pitched sounds, such as an infant crying.
