IEC 60118-13:2016 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 fourth edition cancels and replaces the third edition published in 2011 and constitutes a technical revision.
