Abstract
There are several reasons to be concerned about sound musicians' hearing exposure and its effects on musician's hearing and health. Musicans spend a varied amount of time practicing, playing solo and as a member of different groups. The objective of this study was to investigate the sound pressure levels among members of the militaries band from Curitiba - Parana and the effects in hearing and extra-hearing. The study group consisted of 50 members of the Military Band. The subjects ranged in age from 21 to 54 years old. Measured sound pressure levels during a rehearsal indicated mean levels that instantaneous from 90.ldB(A) to 110.3dB(A),with average levels 91 to 96.2dB(Leq). The subjects answered questionnaires and underwent pure-tone audiometry. The most common complaints with were tinnitus (76%), hearing disabilities (54%) and hyperacusis (30%). Noise induced hearing loss was present on 32%. This study suggests the need for periodic informations and a specific legislation tailored to music professionals.
