[*] "The membrane is tuned to resonate at different frequencies..." (About
basilar membrane). If you say something 'is tuned' then you imply a tuner at
work. Maybe he's religious and is implying a god tuned it but that's at odds
with what is mostly a scientific 'paper'. Simply saying 'The membrane
resonates at different frequencies....' saves words and is far more accurate
scientifically. That ths is but one example of the things that jarred with
me. (I have a background in hard science and as such have difficulty with
quasi-scientific articles.)

It's poorly expressed. Sounds create standing waves in the basilar
membrane, the location of the standing wave corresponding to the
frequency. The hair cells at the location of the standing wave are
stimulated by the basilar membrane. (Those of us with tinnitus have
hair cells at specific locations continuously transmitting, which
slightly messes things up.)

Yep that sounds a lot better. My condolences on the tinnitus.

I used to do soundmixing / stagelighting for live gigs a few deacades ago
and the band I worked with didn't have very long cables so I was never far
from a PA speaker stack. I'd get temporary tinnitus that would last for
days. I'd hate to have it permanently.

If you remember old CRT tellies which had a high-pitched whistle -
what I have is the same as that. Although it's there all the time, I'm
not normally conscious of it. And I think it was from riding
motorcycles with no ear protection (not exhaust noise, the noise of
wind rushing past a helmet).

My dad used to blame his on being a military pilot.

I have it, and it started at about the same age... and I have never
flown a Spit, or a Fury, or a Venom...

I know exactly the noise you mean. Something to do with the flyback
transformer maybe...

Ok. I rode bikes extensively for a decade when I was younger. Luckilly no
problems here (other than age-realted loss of high frequencies). fingers
