All About Ears, Hearing and Dangerous Decibels

At a site called Dangerous Decibels, there's a virtual exhibit on how we hear and how we can take care of our hearing.

You can listen to various sounds, and then see how tiny hair cells change vibrations into electrical signals which are sent to the brain. There's a picture a hair cell that's been destroyed by a loud noise and will never send signals to the brain again.

There are also decibel measurements and suggestions on ear protection -- and even how to answer back to peer pressure.

Save your Ears!
