Human Auditory Physiology Laboratory


Current Research

  • Examining mu suppression in speech perception and production tasks via electroencephalograpy (EEG)in normal controls and people who stutter.
  • Using event-related potentials to reflect changes in auditory processing and attention in athletes who play contact sports with or without a history of concussion versus athletes who do not play contact sports.
  • Comparing behavioral and neural responses from young and elderly listeners with and without hearing impairment,
  • Comparing neural responses from monolingual and bilingual speakers to their first language in noise
  • Measuring the effects of hormones on physiological and perceptual auditory responses
  • Investigating the role of acetylcholine receptors (nAChRs) in audition
  • Determining contributions to individual variability in speech performance in noise;  Specifically, how a subject’s sex, personality, acceptance of background noise, level of neural activity, and other factors affect their speech performance in noise. Why do some normal-hearing individuals have more difficulty in noise than others?

Lab Description

The Human Auditory Physiology Laboratory (HAPLab) is housed in the Department of Audiology and Speech Pathology. Two sound-treated rooms are located in the HAPLab. Equipment is available to synthesize and generate sound digitally. Responses to sounds can be measured behaviorally, acoustically, or physiologically using commercial and custom-made data acquisition systems. The HAPLab contains IBM-compatible computers plus related hardware. Software is available to carry out all current forms of data analysis. Two computer workstations are available for students conducting research projects in the HAPLab. The HAPLab is connected to the University's mainframe computers via an Ethernet network.
