Credits: 3
Contact Hours: Lec 2 Lab 2 Practicum 0
Tier Rate: Tier III
This course introduces the student to hearing aid components and styles, as well as electro-acoustic measurements of hearing aid function according to the American National Specifications Institute (ANSI). The course begins with coverage of basic hearing aid styles as well as their electronic components such as microphone types, amplifiers, and receivers. The course also introduces methods whereby to troubleshoot and repair hearing aids. Students learn the specifics of ANSI tests that are routinely performed, in order to determine if a hearing aid is functioning normally or not. Students are introduced to linear versus compression signal processing, input/output functions, and concepts of programmability and multi-channel amplification. Students will also learn to take earmold impressions of the outer ear, which are normally done in the clinic for subsequent hearing aid fittings. A hands-on lab forms an integral part of this course.
