PURPOSE: verifying the temporary threshold shift in musicians after a high sound pressure level music exposure in a rock concert. METHODS: the sample has been made up of six band's musicians, who underwent an occupational anamnesis, pure tone audiometry and acoustic reflex measurements, before and after the rock concert. The noise levels of the room and the stage were determined by means of a dosimeter. The results were compared and statically analyzed using the t Student test with significance criterion of p> 0.05. the noise level found in the room and stage during the concert was 98.5 dB. As for the behavioral aspects related to the noise, tinnitus was the most prevalent complaint among the subjects. In pure tone audiometry, statistically significant differences were found in the hearing thresholds, before and after exposure, mostly in the right ear for the high frequencies. The results were also statistically significant at the frequencies between 2000Hz and 6000Hz, for the right ear (p=2.7; p=2.59; p=3.7 e p=2.86), and at the frequency of 4000Hz, for the left ear (p=2.87). The right ear's acoustic reflex has shown the highest index of absence (40%); however, we found statistically significant differences in the presence of the acoustic reflex, before and after exposure, only for the left ear (p=3.64). CONCLUSION: musicians exposed to high sound pressure levels in rock concerts have shown temporary threshold shift at the pure tone audiometry and acoustic reflex measurements.
