title: [Acoustic trauma in classical music players].
abstract: OBJECTIVE
  To confirm the existence of acoustic trauma in classical musicians.
  
  
  METHODS
  Sixty-five volunteers from the Castilla and León Symphony Orchestra were studied. The hearing thresholds of each musician were age-corrected using the ELI and ISO 7029:2000 scales. Furthermore the sound levels of the instruments in this symphony orchestra were studied.
  
  
  RESULTS
  We observed that the sound level of the symphony orchestra instruments is higher than the level permitted by law, ie it constitutes a risk for hearing loss. We also found that 4 kHz hearing loss in the 5th percentile among musicians was double the rate that would be expected for age, and that violinists and viola players showed poorer hearing in the left ear.
  
  
  CONCLUSIONS
  Classical music causes acoustic trauma in musicians and should be recognized as a professional illness. Musicians are obliged to protect their hearing and to undergo regular check-ups.
