[*] "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.)
