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. http://www.ece.illinois.edu/news/headlines/hl-allen-hearing-aid.html 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? Margaret les of the outer hair cells to improve hearing aids. In a healthy ear, how does the feedback back from the brain adapt the coch to allow better hearing in a cocktail situation?
