This 5-hour Master Class demystifies frequency lowering amplification technology, to bring a new level of understanding for clinicians and to empower clinical decision making. A review of the goals of this technology and factors that may influence its effectiveness is included, as well as general guidelines for verification using probe microphone measurements. Finally, a demonstration of the differences between the various techniques in use today concludes this comprehensive 'look under the hood' at frequency lowering amplification.

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.
