Jont,
You have just reminded us of the terrific pioneering research that was
done at Bell Labs by many, yourself included. The unfortunate closing
of the Labs and the spreading out of Bell people may have energized
many other institutions.
I went to your website to look at your recent research on hearing aids.

As a long-term hearing aid wearer (childhood measles/mumps; later
Meniere's), I agree that hearing aids don't work well, especially in
noisy situations. The latest models have many helpful features, but
there's still a performance gap.
If your testing can find the critical cochlear and post-cochlear
components of an individual's hearing loss, what type of signal
processing would be needed to compensate? Phonak and other aids have
some noise reduction algorithms, adaptive directional mikes, multiband
frequency channels, and adaptive compression in multiple listening
programs. Still something seems missing. What else is needed?
I'm also curious on how the olivocochlear connections to the cochlea
affect the ability of a healthy ear to understand speech in noise,
specifically "cocktail" party noise.. Are there any connections fast
enough to respond to the pitch/prosody of speech that could allow
real-time cochlear tuning?
