Hearing and Donuts (Brain and Bagels) Seminar
February 28 @ 8:30 am - 9:30 am
Presenter: Stephen Dennison, PhD Student, Electrical & Computer Engineering; Research Assistant, Binaural Hearing and Speech Lab – Waisman Center, UW Madison
Topic: The Influence of Competing Binaural Cues on Lateralization
We localize sounds in our environment using binaural cues: differences in the loudness and arrival time of sounds between the two ears. For patients with cochlear implants, the extraction and delivery of these cues to the brain is compromised, leading to inaccurate localization. Cochlear implants could introduce spurious cue combinations, leading to confusion about a sound’s true location. Binaural cue combinations are competing if they originate from different locations around the head and would not occur together in natural conditions. How do listeners resolve these kinds of discrepancies between cues? We investigate the impact of competing binaural cues on where listeners hear sounds.
