Must be 20 something yrs ago I purchased this cd to check my hearing. http://www.digital-recordings.com/audiocd/audio.html I think it was mentioned in some article in Stereophile magazine .. Inflation looks to have really increased the price to a ridiculous level now. There seems to be some free tests/tones available "for a limited time" that might help here http://www.digital-recordings.com/hearing-test/ht-products.html. Hope this is useful.
