title: The risks of amplified music for disc-jockeys working in nightclubs.
abstract: OBJECTIVE
  Here, we evaluate the risks of amplified music for disc-jockeys (DJs) working in nightclubs.
  
  
  METHODS
  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.
