This research is part of a larger Program Project [P01] award from NIH National Institute on Aging (NIA) titled "Aging auditory system: Presbycusis and its neural bases" and consisting of four major projects.  Project 1 is focused on investigation of age-related changes in spatial hearing or the brain's ability to represent auditory space.  We use spatial hearing to locate sound sources, to separate one sound from another, and to reduce the negative effects of background noise. A second major focus of Project 1 is to understand how the perception of essential acoustic features (spectral, temporal, and spectro-temporal features) changes with age.  These acoustic features form the basis for speech and music perception.  Our goal is to identify remediation targets and to begin to develop methods to overcome any age-related declines in auditory processing.  To do this, we need volunteers who are young, middle-aged, and older (18 to 85 years old) with and without hearing loss.  Participants listen to speech in the presence of background sounds or artificial sounds with special acoustic features to help us answer those questions.  To better understand the neural basis of perception, we also use EEG recordings that involve listening to sounds while we record activity from the brain. 

Listening sessions will span several 2-hour sessions over days or weeks. We will evaluate your hearing status using conventional audiometry and engage you in several  listening tasks to answer key questions about auditory perception. You will be compensated with an hourly payment for your participation.
