16Insertion Gain

16.1Section overview

Insertion gain is the difference between aided and unaided ear canal SPL (REIG = REAG - REUG). It inherently assumes a sound-field audiogram. For non-linear hearing aids, REIG is stimulus-dependent and the dependency is specific to each hearing aid. Insertion gain fitting methods ignore these facts. Speechmap is recommended for fitting all non-linear hearing instruments.

Refer to 10: Real-Ear Measurement Setup and 11: REM Screen Setup for terminology and information on preparing the system for use and for proper positioning of the client and the probe tube.

This section covers the following topics:

16.2: Insertion gain in SPL	16.6: REAR measurement procedure
16.3: Insertion gain in HL	16.7:SII calculation in Insertion gain
16.4: Audiometric data entry
16.5: REUR measurement procedure
