PURPOSE: To identify the presence of hyperacusis and to investigate the characteristics of uncomfortable sounds, as well as the behaviors triggered by the discomfort in musicians of a Military Band. METHODS: Twenty seven musicians of the Military Band of the Santa Maria Airbase (RS) were studied. Their ages ranged from 22 to 50 years old and military work time from four to 26 years, with daily occupational noise exposure time from two to eight hours. All subjects were submitted to a basic audiological evaluation, sound discomfort threshold test and application of a questionnaire. It was considered presence of hyperacusis when the average of the obtained values on the discomfort threshold in 250, 500, 1000, 2000, 4000 Hertz was less than or equal to 90 decibels, associated with hearing discomfort complaint. RESULTS: It was verified presence of hyperacusis in 37% of the musicians. From these, 50% presented normal hearing and 50% had normal hearing with notch; 80% of them felt the discomfort daily and 20% only after band practice; 70% of the musicians had already avoided some activities, believing that the activity noise would be distressing; 70% of them used ear plugs regularly and 90% referred presence of tinnitus. The sounds that were considered to be distressing by hyperacusics were, predominantly, high intensity sounds. The most common emotional responses towards a distressing sound were tension, anxiety and the urge of repelling from it. CONCLUSION: According to the criteria used in this study, 37% of the studied individuals were classified as hyperacusics, which considered predominantly high intensity sounds to be unpleasant. The main emotional responses before these sounds were: tension, anxiety and the need to repel from the sound. The common characteristics among the subjects classified as hyperacusics were: normal hearing, use of ear plugs, avoidance of activities fearing the discomfort caused by the noise, and the presence of tinnitus.
