HIS-250 Real Ear Measurements
Contact Hours: Lec 2 Lab 2 Practicum 0
This course begins with a review of the fitting methods discussed in the previous fitting methods course (HIS 150). It then continues to describe how to apply these fitting methods. Specifically, this refers to how to measure and verify the respective aided outcomes that were predicted by the fitting methods utilized on the hearing aid manufacturers’ fitting software. Verification includes objective procedures of sound field measurement and/or real ear measurement (REM). Early fitting methods relied upon sound field measurement for verification. Today’s fitting methods rely upon REM. This course will follow the course of REM development, as it evolved along with fitting methods from yesterday until today. Students will determine how much amplification to provide for the client’s hearing loss. They will enter a hearing loss, select a fitting method on the manufacturer fitting software, and proceed to verify the fitting by means of REM. Hearing instrument selection is specifically addressed within this course. Each student will discuss and verify performance features of today’s digital hearing aid algorithms. These include digital noise reduction, feedback suppression and directional microphone performance which were covered in HIS 240. A lab forms part of this course. Prerequisite(s): Grade of “C” or better in HIS 230 and HIS 240 .
