This course will discuss a research study investigating how high-frequency bandwidth influences the recognition of different speech sound classes by normal-hearing listeners. This information provides important benchmark data for potential outcomes with another research study investigating frequency-lowering in hearing-impaired listeners.

Joshua M. Alexander
PhD
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.
