Constant music exposure creates temporary and permanent auditory dysfunction for professional disk jockeys, with average levels at 96 dB, which is above the level at which ear protection is mandatory for industry. Three-quarters of disk jockeys have tinnitus [17] and are at risk of tenosynovitis in the wrists and other limbs
