Hearing aid processing of music is much less thoroughly researched than hearing aid processing of speech. This presentation will report on a study using normal-hearing listeners that evaluated the efficacy of programs specifically designed for music listening in state-of-the-art hearing aids. In addition, an analysis of signal processing and acoustic features relating to the results are discussed.

Joshua M. Alexander
Joshua Alexander is an associate professor at Purdue University in West Lafayette, Indiana. At the University of Wisconsin-Madison, he received a BS, MS, and PhD in Audiology (psychoacoustics) and researched speech perception as a post-doctoral scientist. He also completed clinical and post- doctoral fellowships at Boys Town National Research Hospital in Omaha, Nebraska. The central goal of Dr. Alexander's research is to improve speech understanding and decrease listening effort in hearing aid users. To assist in these efforts, he has developed a PC-based hearing aid simulator that is capable of replicating key features of commercial hearing aids. This tool combined with laboratory measures and models of processing at the sensory, neural, and cognitive levels allows him and his collaborators to explore how and why certain features of hearing aids affect perception and to explore factors that might explain individual differences in hearing aid benefit.
Emily Sandgren is a third year graduate student in the audiology program at Purdue University. She received her BS in Communication Sciences and Disorders with minors in Music and Spanish from Samford University as a member of the University Fellows Honors Program.
