The Maico hearing test unit I got as a kid started at -10db. It was retired because it used stepped attenuators and made a clicking noise between steps. It was determined the switches were worn out by the factory authorized service folks. I had a great time taking it apart, beautifully built, learned about log size steps, silver shorting rotary switches, etc. Of course with later knowledge the actual problem was DC through a leaking capacitor!
People see ENTs for a lot more than hearing loss and they usually test people's hearing when they come in. The two ENT doctors I talked with said that people hearing thresholds usually vary from 0dB to +15dB for normal hearing, even with no bandwidth loss.

Anyway, I think it makes sense that if you have hyperacusis and the world sounds +40dB to +60dB louder to you, then you'll probably do better on the test. Though a person's threshold for hearing probably doesn't change in absolute terms, as far as I know.

But not everyone has the same threshold for hearing, even without damage, it varies. I'm just going by what audiologists and the two ENTs I've talk to said. A better testing method or facility might give different results ... I have no experience with that.

How about the blood flow in (say) your carotid artery or your heartbeat? The brownian motion of air at the eardrum is really going to be noisier than that?

Sorry that I have a life and can't always respond to you instantly.

JJ has never said what you claim he said. Period. Nor has anyone else. What's so hard to understand about that?

If this were the first time you ascribed that incorrect notion to others (last time, I think you ascribed it to me, which was just as much a fabrication), that would be one thing. But it isn't, you've done it again and again, and you've been refuted again and again. At a certain point, one must either believe that you're stupid (which you are decidedly not) or you're willing to lie to try to score meaningless debating points against someone who's not a participant here and can't correct your false assertion himself (which I find very disappointing).

Speaking of 'fabrications' SY how about the Jack Bybee comments by you on this website? Any proof, any evidence, any first hand knowledge?
I made a generalization of what I think jj and his bunch are trying to do with audio. Do they not resist SACD, and think that MP-3 is A-OK? Didn't jj invent MP-3, or did I get that wrong?

also, the number of people who were in need of brake adjustments,

seemed to be higher than what seemed normal.

easily heard, when careful listening was practiced.

not sure how high of a frequency that sort of thing is.

(the neighbors dog, actually clued the brake problems,

as he heard them first,and complained early and often,

by howling)

Wow, now I am either 'stupid' or a 'liar'. Well SY, talk about debating tactics. Perhaps I could be 'mistaken'? Just because I have directly debated jj over the years, does that count for anything. I once told jj, that it was his business to remove as much as he could and still get away with it, but my business was to take what I had and get the most from it. That is the difference between us. I have great respect for jj, as a scientist, I always have.
