Abstract
Mass transit commuters are regularly exposed to excessive noise levels. The use of personal listening devices (PLDs) adds further stress on the auditory system as commuters listen at high volume levels to mask the background noise encountered during their daily commute. In fact, studies show that PLD users increase the volume of their devices when in areas with high background noise, thereby creating further risk of noise-induced hearing loss (NIHL; Ear Hear. 2007;28[3]:290 http://bit.ly/2mJETVb).
