IEC 61669-2015 电声学--助听器的仿真耳声学特性的测量设备 Electroacoustics - Measurement of real-ear acoustical performance characteristics of hearing aids

This International Standard gives recommendations and requirements for the measurement
and estimation of the real-ear acoustical performance characteristics of air-conduction
hearing aids and for the measurement of certain acoustic properties of the ear related to the
application of hearing aids.
Measurements of real-ear acoustical characteristics of hearing aids which apply non-linear or
analytical processing techniques are valid only for the test signals used and conditions
employed.
The purpose of this standard is to ensure that measurements of real-ear acoustical
performance characteristics of a given hearing aid on a given human ear can be replicated in
other locations with other test equipment.dition 2.0 2015-11 INTERNATIONAL STANDARD NORME INTERNATIONALE Electroacoustics – Measurement of real-ear acoustical performance characteristics of hearing aids électroacoustique – Mesure des caractéristiques de performances acoustiques des appareils de correction auditive sur une oreille réelle IEC 61669:2015-11(en-fr) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2015 IEC, Geneva, Switzerla
