The WHO Technical Officer for the Prevention of Hearing Loss and Hearing Loss has proposed to provide the smartphone with a speedometer, a measurement system that shows the level of sound received by the listener, and warns if the sound exceeds the maximum allowed.

UN experts have issued new guidelines for smarter use of smartphones, including guidelines for prevention of deafness and associated diseases, such as tinnitus.

The World Health Organization (WHO) and the International Telecommunication Union (ITU) have launched an effort to address the lack of awareness about the volume of noise, which can be considered excessive noise, at a time when health data show that one out of every two young people listens to excess levels of sound.
