Organization: ASA
Publication Date: 3 April 1987
Status: inactive
Page Count: 24
scope:

This standard is intended to meet the need for specifications of air conduction hearing aid performance parameters and their tolerances. The quantities suggested for specifications and tolerances are considered to be useful for comparing performance characteristics of different hearing aids or for comparing performance characteristics of a hearing aid with published specifications.

Tolerances are given relative to specified characteristics supplied by a manufacturer. In the .case of "custom" or "made-to-order" hearing aids, individual test data are to be supplied. The tolerances specified in the standard will apply to the individual test data supplied.

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 electroacoustical characteristics.
