Hearing Science Laboratory

Directed by Shaum P. Bhagat, Ph.D., the Hearing Science Laboratory (HSL) is housed in the School of Communication Sciences and Disorders (formerly School of Communication Sciences and Disorders) at the University of Memphis. The research conducted in the HSL is focused on examining otoacoustic emissions measured in typical and impaired listeners. Topics investigated include cochlear amplifier characteristics, suppression of otoacoustic emissions, and binaural interactions. Several studies recently completed in the HSL have provided insights into the effects of intense sounds and ototoxic drugs on otoacoustic emissions measured in children and adults.

CURRENT RESEARCH
  • Application of otoacoustic emissions in the detection of ototoxicity from chemotherapy drugs or acoustic overstimulation
