16 Insertion Gain
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 linear and non-linear hearing instruments.
Refer to On-Ear Measures - Setup and On-Ear Measures Screen Setup for terminology and information on
preparing the system for use and for proper positioning of the client and the probe tube.
