This standard describes methods for a test which simulates the acoustical effects of a median adult wearer on the performance of a hearing aid. It establishes certain guidelines for simulated in situ measurements of hearing aids; it describes a simplified method for simulated in situ measurements of hearing aids and a description for determination of the directivity index (DI) of directional microphones in hearing aids in the horizontal plane., and it also specifies tolerances.
