Aceitação de protetores auditivos pelos componentes de banda instrumental e vocal

Abstract

There are barriers to effective hearing protection among musicians. Aim: To investigate the acceptance of hearing protection aids in members of an instrumental and voice music band. Material and method: A prospective study of 34 members of the Municipal Indaial Band. Sound pressure levels were measured during a rehearsal, indicating mean levels ranging from 96.4 dB(A) to 106.9 dB(A). Subjects answered questionnaires and underwent audiometry. They attended a lecture in which folders and hearing protection aids were provided; subjects were asked to try using the protectors for 3 months. Results: At the end of the study period, 56.2% reported not liking hearing protection, while 43.7 % accepted such protection. The most common complaints were discomfort with sounds (58.8 %) and tinnitus (47%). 77.1% said that music might cause hearing impairment. 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 when median thresholds were compared with those from unexposed controls. Conclusion: Although most subjects seemed aware of the risk, few took preventive measures against hearing loss. This suggests the need for periodic educational campaigns and specific legislation tailored to music professionals.

Ruído e equilíbrio: aplicação da posturografia dinâmica em indústria gráfica

“…Isto significa que alterações importantes podem ocorrer nas estruturas labirínticas sem a existência de muitas queixas por parte dos indivíduos. Por esta razão, o uso de protetores auriculares é importante não somente para proteger a audição, mas também para a preservação da função vestibular [13][14][15][16] .…”

Percepção e o impacto da música na audição de integrantes de banda militar

“…As queixas auditivas mais relatadas foram: o zumbido, a intolerância a sons intensos e a perda auditiva; na maioria dos casos, a configuração da perda auditiva observada foi característica de perda auditiva induzida pelo ruído (PAIR) (5,(7)(8)(9)(10)(11)(12)(13)(14)(15)(16) . Diante do exposto, o comprometimento do sistema auditivo, como as lesões cocleares, a hiperacusia e o zumbido podem interferir no desempenho do músico, dificultando a percepção de tons e timbres, prejudicando o equilíbrio entre os instrumentos, afetando-o tanto profissionalmente como na sua vida social (17)(18) . Desta maneira, o objetivo da presente pesquisa avaliar a exposição à música elevada, a percepção da sua intensidade e seu impacto na audição em integrantes da banda militar do exército do Paraná.…”

Audição e qualidade de vida de músicos de uma orquestra sinfônica brasileira

“…Other studies have shown the presence of those symptoms in different musical groups, such as an instrumental band (7) , which had tinnitus reported by 47% of the musicians, and intolerance to intense sounds by 58.8%, as well as a military band (2) , which had tinnitus reported by 76% of its members.…”

“…Among the several hazardous factors for hearing in this professional practice, can be mentioned the length of exposure, music intensity, the acoustics of the orchestra rehearsal setting, proximity of sound sources (placement of the musician in the orchestra and in the family of instruments that his/her instrument belongs to), choice of the repertoire and repetition of specific musical passages (5) . Even though mild hearing losses hardly hinder communication, they may impair timbre recognition and instrument tuning, thus they should be identified early (2,6,7) . The difficulty in identifying timbres and variations in sound intensity may lead the musicians to misleading perceptions, that is, by determining whether intensity or frequency has changed, they may assume that what they have heard is a high-pitched sound (frequency), while it actually is a crescendo (8) (increase in sound intensity).…”

“…According to a study (9) , one of the reasons for that is that many researchers wrongly believe that music, for being associated with leisure and pleasure, is not an occupational activity. Moreover, there is not specific legislation in Brazil that prevent musicians from related impairments to loud music (7) . The amount and quality of studies published up to date in the area of musician medicine show how this research field has lagged behind the other occupational sectors (10) .…”
