Being an audiophile (and ex audiophool) owning high-performing audio devices, I decided to have a professional hearing test done to see to what degree I rather have OCD. Or actually, the deciding factor was more likely that it was free of charge. :-)
The test consisted of three parts: 1) pure-tone audiometry using air conduction at 125-8000 Hz 2) pure-tone audiometry using bone conduction at 250-4000 Hz 3) pure-tone audiometry using bone conduction at 250-4000 Hz, with a masking (white or pink?) noise in the other ear using air conduction. The result was that my hearing was completely normal. Nevertheless I was very surprised by the difference between the ears. According to the audiologist, the interval that is considered normal is up to 20 dB. Also, what is considered normal in absolute terms seems to be up to 25 dB hearing loss. (See for instance http://www.healthyhearing.com/content/faqs/Hearing-loss/Test/41775-Degrees-of-hearing-loss.) Interestingly enough, the audiologist said that they never test frequencies over 8 kHz, as the ear is too easily damaged. (Remember that on average one can only hear 20 kHz at the threshold of pain. And yes, that's how to correctly interpret the Fletcher-Munson curves.) Another dimension would of course be how trained the brain is to interpret the sounds. I used to play the violin and the piano for many years and also sang in choirs. Therefore, I'd like to think that these activities trained my brain quite a bit. My sister, who is a talanted musician, has significantly better hearing than me when it comes to hearing what's going on in a symphony orchestra, but as life is not long enough we have made no formal tests to prove that. I hope I'm at least better than average, but maybe it's too long ago and therefore just wishful thinking. Anyway, I don't know any way of testing this in an objective way. My conclusion is that it's good that I stopped obsessing about equipment a number of years ago and instead concentrated my OCD on room correction. Maybe I should even stop paying attention to everything but the music itself? (On the other hand, I really can't stand listening to a lousy system and I immensely enjoy listning to a good system, so that would be a huge challenge.)
