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
