One of the approaches taken by Make Listening Safe is to promote the development of features in PLS to raise the users' awareness of risky listening practices. In this context, the WHO partnered with the International Telecommunication Union (ITU) to develop suitable exposure limits for inclusion in the voluntary H.870 safety standards on "Guidelines for safe listening devices/systems."[1] Experts in the fields of audiology, otology, public health, epidemiology, acoustics, and sound engineering, as well as professional organizations, standardization organizations, manufacturers, and users are collaborating on this effort.[2]
