Interactive hearing tutorial

I found this National Institute of Health hearing tutorial interesting, especially the interactive pitch/loudness display on Lesson 3 - Pitch Me A Curve.
(Click on the Hearing Response tab.) It confirms that I hear nothing at 2000hz and beyond.....well, not exactly nothing. I hear a snap at 20db and higher.

Very interesting. I especially liked the Filtered Sound demo. My natural hearing cuts out above 4000 HZ so it was interesting to see what the difference between that and normal hearing sounds like. I also listened to the 2000 HZ level to get an idea of what your sound experience is.
Thanks for posting this.
