BS EN 61669:2016 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.Cross References:IEC 60601-1IEC 60601-1-2IEC 60318-5IEC 60942IEC 61260-1ISO 266ISO 8253-2ISO/TR 25417EN 60318-5EN 60601-1EN 60601-1-2EN 60942EN 61260-1EN ISO 266EN ISO 8253-2IEC 60050-801IEC 60118-0IEC 60118-7IEC 60118-8IEC 60118-15IEC 60318-4ISO/IEC Guide 98-4JCGM 106EN 60118-0EN 60118-7EN 60118-8EN 60118-15EN 60318-4All current amendments available at time of purchase are included with the purchase of this document.
