The risks of amplified music for disc-jockeys working in nightclubs.

OBJECTIVES: Here, we evaluate the risks of amplified music for disc-jockeys (DJs) working in nightclubs. DESIGN: Sound level measurements were performed within the DJ mixing booths. A questionnaire was used to obtain exposure to noise and length of time in the profession. Audiograms and tinnitus pitch matching was also performed. RESULTS: The DJs' audiograms showed the expected noise-induced hearing loss at 6 KHz, but also low frequency losses at 125-500 Hz. Three quarters of them have tinnitus with a frequency corresponding to hearing loss. CONCLUSIONS: This study highlights the risk of amplified music on hearing and tinnitus.
