• Description:
  The aim of this study was to examine the music exposure and hearing of disc jockeys (DJs). We conducted personal noise dosimetry on 30 DJs and interviewed them regarding their hearing and their job. We conducted pure-tone audiometry, and transient and distortion product otoacoustic emissions before their exposure to music during their work. This first test was preceded by a period of at least 12 hours without exposure to music or noise. We repeated the pure-tone audiometry and otoacoustic emissions after their music exposure, and poorer performances were registered in all retests. The nightclubs' average sound level ranged between 93.2 to 109.7 dB(A). Statistical analysis showed significant bilateral temporary threshold shifts at all frequencies between audiometry performed pre- and post-exposure to amplified music. Transient otoacoustic emissions showed a significant difference in bilateral amplitude and reproducibility at all frequency bands tested. The comparison of distortion product otoacoustic emissions results pre- and post-music exposure showed there was a significant difference in amplitude. Music exposure was associated with temporary and permanent auditory dysfunction among professional DJs. [Description provided by NIOSH]
