Testing Hearing Aids with a Broad-Band Noise Signal
The purpose of this document is to define a test method with which to characterize the steady-state frequency response and input/output characteristics of hearing aids as the input level varies. This method is particularly useful for those haring aids that have automatic gain control or other types of adaptive circuitry.
