To check on my own hearing I made some recordings of sine waves -- now have posted them on

Ear Test 11KHz
Ear Test 12KHz
Ear Test 13KHz
Ear Test 14KHz
Ear Test 15KHz

Each has 5 quiet tones of 6-8 seconds at 0.2 KHz apart, first all five for left ear, then all five for right ear. There is a poll in the Community area of soundclick, in the 'General' forum -- would be interesting to see how our ears are doing, so please answer the anonymous poll if you are willing.

As an aside, I felt that I lost some hearing several years ago when using hardward synthesizers heavily -- Korg, especially -- but that over the pasr recent years, with software samplers, my hearing has been more stable. Anyone else with this kind of experience?
