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.
