ITU-T - H.870
Guidelines for safe listening devices/systems
|Publication Date:||1 March 2022|
This Recommendation describes the requirements on safe listening devices and systems, especially those for playing and listening to music, to protect people from hearing loss.
As market trends have blurred the distinction between some listening devices and personal audio devices, use-cases are included to ensure this Recommendation applies as widely as reasonably practicable.
NOTE 1 - Some of these use-cases follow the principle of classifying energy sources and prescribing safeguards against those sources as enshrined in [IEC 62368-1].
For the purposes of this Recommendation, the following types of devices are excluded:
- two-way communication devices (such as walkie-talkies, etc.);
- rehabilitative and medical devices (e.g., hearing aids, FM systems and other assistive listening devices (ALD) approved as part of hearing aid and cochlear implant systems, etc.);
- personal sound amplification products/devices;
- professional audio equipment and devices.
NOTE 2 - There are concerns about the exposure to sound from portable game consoles, but this is for future study.
