According to the World Health Organization, more than one billion 12 to 35-year-olds, risk irreversible hearing loss from exposure to loud sounds such as music played on their smartphone. To prevent noise-induced hearing loss and related conditions such as tinnitus – commonly experienced as a ringing sound inside the ear – monitor how loud, and for how long, you listen to music. Sound is measured in units called decibels or dBA. Music through headphones at maximum volume measure 94-110 dBA. Sounds at or above 85 dBA can cause hearing loss.
