Visual Distraction and Speech Recognition in Noise

This project is concerned with visual distractors that are present during communication in everyday situations, and their impact on a listener's ability to understand speech in noise. The project also investigates possible age-related differences in the ability to ignore the visual distraction and attend to the auditory message.

Working Memory and Speech Perception as a Function of Age

The purpose of this study is to examine auditory working memory as a function of age and its relationship to listeners' ability to process rapid speech, speech in noise, and speech in varying levels of context.  Some of this work is being conducted in collaboration with colleagues from Walter Reed National Military Medical Center.

Effect of Frequency Manipulations on Spatial Release from Masking in Simulations of Cochlear Implants for Single-sided Deafness in Competing Talker Situations

The purpose of this study is to evaluate the effects a frequency mismatch will have on speech understanding in simulations of cochlear implants for single sided deafness. The task involves listening to a target talker and ignoring masker talkers, some of which are vocoded to simulate what a CI user might hear.


Neuroplasticity and Auditory Aging

The overall objective of this project is to establish an efficacious auditory-cognitive intervention model for age-related hearing loss (ARHL) that demonstrates positive neuro-plastic change in older individuals’ central auditory pathways. The ultimate goal is to improve auditory processing and speech perception in everyday challenging situations that include noise, reverberation, other acoustic distractors, and talkers who speak at a fast rate.


Effects of Age on Benefit of Cochlear Implants

This series of projects (conducted in collaboration with Drs. Matt Goupell and Samira Anderson and students Maureen Shader, Casey Gaskins, Lauren Evans, and Alex Presacco) examines the hypothesis that age-related changes in temporal processing abilities impact the benefit afforded by cochlear implants to older people.
