If You are Performing an Insertion Gain Measurement, Do You Need to Subtract the REUR If It’s a Non-occluding Fitting?

Non-occluding fittings present unique challenges and considerations when conducting real-ear measurements (REM). For clinicians who subscribe to the insertion gain method for verifying devices to prescriptive targets, confusion can arise regarding how to properly account for the real-ear unaided response (REUR) or real-ear unaided gain (REUG), given it is typically not impacted with open fittings.
