This standard describes certain hearing aid measurements and parameters that are deemed useful in
determining the electroacoustic performance of a hearing aid. Some of these lend themselves to
setting of tolerances for the purpose of maintaining product uniformity and for compliance with the
performance specified for a model.
It is not the intent of this document to restrict the variety of hearing aid performance available nor to
inhibit in any way advances in the state of the art.
This standard is limited to the specification of certain electroacoustic characteristics based on
sinusoidal and other steady-state test signals. Measurements described in this standard are not
intended to reflect in situ performance of hearing aids, directional performance of directional hearing
aids, or certain performance properties of digital hearing aids, such as processing delay.
Notes in the standard are not considered to be part of the standard.
