Unit 5 Ch 4 - Part 2. Hearing and the Auditory System!

The organization that gives out the Nobel Prize has a great website about the ear and how it works.

If you're having trouble understanding the accessory structures and the cochlea this site is for you.

Animations and interactives that explain the ear.

The Sumanas inc. video goes into great detail about the inner ear.
Another video on YouTube is great 3D animation that takes you into the ear as if you are a sound wave... it demonstrates the movements in the middle and inner ear with classical music... fantastic piece. The link is at http://youtu.be/PeTriGTENoc - since it's YouTube it may not work at school... 

Hearing Tests: 
You need over-the-ear headphones and a decent computer to use this (not medically accurate) hearing test, but it's interesting to check out even if you don't have the right set-up.  Keep your volume at a moderate level, and if you stop hearing the tone DO NOT increase the volume to try to hear it. 

This website has lots of different tone generators including this hearing test

This one:  http://youtu.be/h5l4Rt4Ol7M  is a YouTube video, so it may not work at school. 
Mr. Cantor who was born in 1964 can hear sounds below roughly 14,000 Hz. How about you? -- 
YouTube actually compresses  audio, so this may not be accurate. Try the link above for more accuracy.
