How do hair cells in the inner ear help you to hear?

When sound waves hit them, they convert the vibrations into vibrations to the brain

When sound waves hit them, they convert those vibrations into electrical currents that our auditory nerves carry to the brain.

When sound waves hit them, they act as a conduit to the brain and vibrate the brain

1

What happens in your ear when you hear exceptionally loud noises?

your stereocilia become damaged and mistakenly keep sending sound information to the auditory nerve cells.

A bell is formed in the ear canal and the sound waves make it ring consistently until it stops vibrating

The loud noise causes the small hairs to vaporize and the brain thinks that the hairs are still there so there is a ringing

1

What can you do to protect your ears from hearing loss?

Turn the volume in your headphones to 11!

Get as close to the speakers at a concert as you can
