- Equal Loudness Contours and Audiometry - An About.com visitor recommended this site. His comments: "Here's the best one I've seen yet. It features tones from 20 Hz to 16
KHz. You click until you can barely hear the tone and it registers the level.
A word of caution: I used a set of noise-canceling headphones with a good frequency response. Inexpensive headphones or ones that do not cancel noise may make any test inaccurate.
Another word: The tones (to me) begin and end with a click -- that will make some of the uninitiated think they heard a sound. Listen for the actual tone."
Another About.com visitor wrote: "The UNSW chart of bars was helpful, you can compare your profile against a standard graph. However, it does not test whether the volume you perceive the frequencies at normal levels or not."

From an About visitor: Was unimpressed, only 5 tones, no set volume level or spl check. - WorldHearing.com - An About.com visitor wrote: Too confusing.
- Telecare Health - An About.com visitor wrote: It requires you to register with them and then sign in for the test. All free. Well thought out and accurate test.
