IEC 63087:2026 sets out the requirements for the provision of assistive listening systems (ALS) in places or situations where there is a benefit for hearing-aid, cochlear implant, and other hearing device users, compared to listening to the acoustic signal directly at that location.
This document applies to all ALS used for communication, entertainment, or educational purposes in public, private, domestic and public transport installations.
This document does not apply to other forms of audio transmission, for example simultaneous interpretation or audio description or audio-streams other than those broadcast as part of an ALS. However, this document provides useful ancillary information for such systems which can be applied.
Personal listening and intelligibility enhancement devices and systems are also included within the scope as they constitute a special case and incorporate some unique features and requirements (Annex C).
This document does not apply to hearing aids and medical hearing devices themselves or to speech enhancement and communication systems found in some private motor vehicles which are sometimes referred to as assistive listening.
