CTA has recently published ANSI/CTA-6020, Assistive listening devices and systems for active assisted living - Part 1: General IEC 63087-1:2021. IEC 63087-1:2021 specifies requirements, and the associated methods of measurement, for the electroacoustic performance of personal listening systems.

This document specifies requirements for the provision of assistive listening in audio, video and multimedia systems and equipment. The requirements are of different kinds, because of the diversity of the hardware concerned.
This document does not apply to hearing aids. Also excluded are devices entirely worn on or in the ear, which cannot be measured independently.
