HIS-240 Compression & Digital Feature
Contact Hours: Lec 2 Lab 2 Practicum 0
Types of signal processing that are used in digital hearing aids are covered in detail in this course. These types range from linear amplification to the myriad types of compression, such as: output limiting, wide dynamic range compression, and expansion. Electro-acoustic testing measures (ANSI testing) will be briefly covered again in this course. Additionally the adaptive features such as Digital Noise Reduction, Adaptive Directionality, and Adaptive Feedback Cancellation as incorporated in today's digital hearing aids will be explored. Successful completion of this course relies heavily on absorbing concepts, as well as listening to examples of commonly prescribed hearing aids. Course delivery consists of classroom lectures. Prerequisite(s): Grade of "C" or better in HIS 140 and HIS 150 .
