Martin McKinney - Music Perception and Hearing Impairment

Date: 
Fri, 11/04/2011 - 1:15pm - 2:30pm
Location: 
CCRMA Seminar Room
Event Type: 
Hearing Seminar
We mostly talk about speech when we discuss hearing impairments.  But we're at CCRMA and care more about music!

I'm happy to announce that Martin McKinney, a senior researcher with Starkey Laboratories (in Minneapolis), will be talking about his music perception work at this week's CCRMA Hearing Seminar.  Martin and his colleagues have done some amazingly good work understanding the effect of hearing impairments on cognitive load.  I'm really excited that they are turning their intellect towards music.

Hearing aids of yore were simple amplifiers.  New aids also do compression to account for the limited dynamic range that one can hear when impaired.  But what really happens to our hearing as we age?  And what can we do about it? 

We've talked about people losing their ability to understand speech in cocktail parties.  And music is one of the more difficult auditory environments to perceive and understand.  Martin's group is reporting the first of their studies on how impairments affect our musical perception abilities.

    Who:    Martin McKinney (Starkey Labs)
    Why:    Because music perception is important!
    What:    Music Perception and Hearing Impairment
    When:    Friday November 4 at 1:15PM
    Where:    CCRMA Seminar Room

Bring your musical ears to CCRMA and we'll talk about what we all have to look forward to (as we age. :-(

Music Perception and Hearing Impairment
Historically, hearing aid technology has been designed to improve
speech perception, especially in noise.  Because music differs from
speech in its signal properties and its relevant perceptual
attributes, it should be processed differently in hearing aids to
optimize its perceptual restoration. We review here the impact of
sensorineural hearing loss on basic psychoacoustic phenomena and
extend this to relevant attributes of music perception.  We show how
hearing loss affects pitch, loudness, timbre and dissonance, and how
we can predict these effects using computational models. The goal in
developing the models is to use them as a guide for the development of
hearing aid technology.  Finally, we review current methods for both
diagnosing and treating hearing loss and discuss the need for reliable
quantitative measures of music-perception deficits due to hearing
loss.
