Three Methods for Estimating the Middle-Ear Muscle Reflex (MEMR) Using Otoacoustic Emission (OAE) Measurement Systems

: A sensitive measure of the middle-ear muscle reflex (MEMR) is needed when making other sensitive audiological tests where activating the MEMR could confound and confuse test results. In this report we document and describe three related methods for making this sensitive MEMR measurement using the OAE and MOCR measurement modules in the Mimosa Acoustics HearID system. All three methods can sensitively detect small MEMR; however, for many ears, test variability is too high to make a clear determination of MEMR threshold.
