Course Description
This course introduces the student to the hearing aid fitting software that is commonly used in clinics today. Representatives from the various hearing aid manufacturers will be invited to present to our students to familiarize the students with the unique aspects of their fitting software. Students will also learn about peripheral devices, used along with hearing aids to stream inputs from telephones, televisions, iPADs, iPODs, etc., in order to increase the signal-to-noise ratio (SNR); namely, increase the loudness of speech compared to background noise. This course will also introduce students to assistive listening devices (ALDs) that are used by the hard-of-hearing and deaf populations. These include alerting devices, telephone devices, and also devices that increase signal-to-noise ratio (SNR).
