IEC 63087-1:2021
Assistive listening devices and systems for active assisted living - Part 1: General
Product Details
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. Existing IEC standards for methods of measurement are normatively referenced if they exist. Methods of measurement and performance requirements are specified in IEC 63087-2.
This document does not apply to hearing aids. Also excluded are devices entirely worn on or in the ear, which cannot be measured independently.
