This part of IEC 60118 covers relevant EMC phenomena for hearing aids. Hearing aid immunity to high frequency fields originating from digital wireless devices such as mobile phones was originally identified as the most relevant EMC phenomena impacting hearing aids. Since the inclusion of RF generating components within hearing aids, such as digital signal processors or wireless transceivers, additional EMC compliance requirements apply. The EMC requirements now included are radiated emissions and immunity to electrostatic discharge, power frequency magnetic fields, and radiated RF electromagnetic fields. Requirements associated with connected power and signal lines are not included.

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.
