I had my hearing tested at a centre that specialises in auditory testing after I
claimed to be able to hear things many others couldn't. Bearing in mind most of the
doctors at his centre had more letters after their name that you could fit on the
average MD label, and the equipment they were using was highly specilised, I doubt
they would concurr with your assessment they were using a cheap function generator.
