CSA Z107.56 AND SAFE USE OF MUSIC PLAYERS
by Tim Kelsall, CIH, ROH, INCE Bd.Cert.
Tim Kelsall writes about the concern over young (and older) people listening to personal music players as part of their daily life and how to protect them from hearing loss. CSA Z107.56 includes a section on estimating noise exposure under headsets which puts this issue in perspective. Based on research indicating that most people set the volume of music and speech at about 15 dB above the existing ambient the standard provides an estimate of their noise exposure.
