The aim of this study was to assess the sound levels and the occurrence of temporary threshold shift of Disc Jockeys (DJs) who work in nightclubs in the city of Curitiba, capital of Paraná State, South of Brazil. Thirty DJs in Curitiba were assessed via pure tone audiometry, before and immediately after their exposure to electronically amplified music. Measurements of the sound levels to which the individuals were exposed were taken in a 1-hour minimum and 2-hour maximum periods of time. The equivalence level results ranged between 93.2 dB to 109.7 dB. Audiometric results obtained before and after their exposure to amplified electronic music were compared and an assessment of the time of exposure to that music was performed; levels of noise yielded by nightclubs were analysed; auditory complaints were researched and the need of implementing a project for preventing auditory loss in the work environment and providing guidance for the population under study was assessed.
