Sridhar Kalluri on speech-in-noise perception
Date:
Fri, 10/26/2018 - 10:30am - 12:00pm
Location:
Seminar Room at the Knoll
Event Type:
Hearing Seminar But overall our ears are not so lucky. Noise and competing sounds mask the sound we want to understand, and our own limitations further degrade the experience. What is it about the auditory system that exasperates the effects of noise, and what can we do about it?
Who: Sridhar Kalluri
What: Improving speech perception in adverse acoustics, what’s hard about it?
When: Friday, October 26, at 10:30AM
Where: CCRMA Seminar Room (Top Floor of the Knoll)
Why: What the heck limits our perception in noise?!?!!?!?!
Bring your favorite ears to CCRMA and we’ll make sure there is more signal than noise.

Title: Improving speech perception in adverse acoustics, what’s hard about it?
Sridhar Kalluri
Abstract:
Perception of speech in adverse conditions (e.g. amidst background noise) has remained a prominent problem despite fascinating advances in hearing technology over several decades. I will review two experiments that address the constraints on speech communication success for listeners with hearing impairment. Auditory, cognitive, and technical factors all play a role. These constraints help understand why it has been difficult to improve speech understanding in adverse acoustics. I will also give overviews of a couple of promising research directions for improving speech perception through hearing technology. I hope these will spark discussion about these and other approaches that have promise for improving communication outcomes for hearing-aid users and beyond.
Sridhar Kalluri was trained as a speech and hearing scientist at MIT. He studied the auditory cortex at the University of Maryland as a postdoctoral researcher. Subsequently, he has focused on applying the speech and hearing sciences to improving hearing aids at the Starkey Hearing Research Center. As a principal researcher there, he studied binaural and spatial hearing, auditory scene analysis, and cognitive interactions with hearing aids. Most recently, he was director of hearing sciences research at Starkey, where his team made diverse scientific and product contributions, including binaural features, novel signal processing, cognitive and spatial hearing outcome measures, and tinnitus diagnostics, amongst many contributions.
