H.870
# H.870

H.870 "Guidelines for safe listening devices/systems" (formerly F.SLD) is an ITU-T Recommendation, developed in collaboration with the World Health Organization. It specifies standards for safe listening to prevent hearing loss and was first approved in 2018. In March 2022, version 2 was approved and published.

## Apps

In order to make the Guidelines available as widely as possible, the WHO released Android and iOS apps.

## Toolkit

In order to ensure widespread implementation of this standard, WHO, ITU-T and ITU-D’s Digital Inclusion Programme developed a Toolkit for Safe Listening Devices and Systems.

## Inter-Agency Collaboration on Digital Health

H.870 and the work on safe listening is part of the Inter-Agency Collaboration between the ITU and the World Health Organization on Digital health, which is undertaken primarily through ITU-T Study Group 16 and the ITU-WHO Focus Group on Artificial Intelligence for Health (FG-AI4H).
