RESUMO

The objective of this study was to investigate the acceptability of the use of hearing protection among the members of an instrumental and vocal band during their rehearsals and performances. The study group consisted of 34 members of the Municipal Indaial Band. The subjects ranged in age from 19 to 76 years old; 80% were men and 17, 1 % were women. Measured sound pressure levels during a rehearsal indicated mean levels that ranged from 96.4 dB(A) to 106.9 dB(A), with maximum levels reaching up to 110.9 dB(A). The subjects answered questionnaires and underwent puretone audiometry. They also attended a lecture when informative folders and hearing protection were provided; subjects were asked to try using the protectors during a 3- month period. At the end of the study period, 56.2% reported they did not like hearing protection, while 43.7 % liked it. The most common complaints were discomfort with sounds (58.8 %) and tinnitus (47%). 77.1% reported that the music might cause hearing impairment. When median thresholds were compared with those from age-matched unexposed controls, a statistically significant difference was observed in the right ear at 4 and 6 kHz and at the left ear in 3, 4 and 6 kHz. Although most subjects seemed aware of the risk, few took any preventive measure against the hearing risks. This suggests the need for periodic educational campaigns and specific legislation tailored to music professionals.
