FastFacts 16.2: Insertion gain in SPL
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.
