IEC 60118-13:2019 covers the relevant EMC phenomena for hearing aids. Hearing aid immunity to high frequency fields originating from digital wireless devices such as mobile phones was identified as one of the most relevant EMC phenomena impacting hearing aids. IEC 60118-13:2019 cancels and replaces the fourth edition published in 2016 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) it introduces a new measurement method and set of EMC requirements for hearing aids immunity to mobile digital wireless devices; b) generic EMC requirements for hearing aids are no longer included – should be covered by other standards as appropriate.
