Abstract
Analyze the interference of using the voice amplifier in vocal dose of non-dysphonic teachers. This is an experimental study comparing people from the same ambience compound for 20 teachers from municipal elementary school in Belo Horizonte/MG. After consent, the participants were requested to answer the vocal symptom scale questionnaire (ESV) and later participated in two different moments of the study, for which they randomly selected. In the first moment, the participants used only the vocal dosimeter and in the second, they used the vocal dosimeter and the voice amplifier. The measurements were recorded by the device for 1h40m, in the classroom that the teachers taught. The time between the two measurements was one week, with the same room, the same time and the same discipline being taught, at both times. The intensity parameter was the only one that showed difference with the use of the voice amplifier. Use voice amplification while non-dysphonic teachers are teaching doesn't affect the fundamental frequency and vocal dose measure in the acoustics parameters. The vocal intensity is smaller when teacher uses the vocal amplification.
Highlights
The measurements were recorded by the device for 1h40m
Os resultados desta pesquisa sugerem que professores não disfônicos podem ser beneficiados com o uso de amplificação sonora, pela diminuição da intensidade vocal, o que provavelmente pode ser um fator protetor da saúde vocal deste grupo profissional
Summary
Os dados encontrados demonstram que a intensidade vocal das professoras não disfônicas, sofreu redução significativa com o uso do amplificador de voz. Os resultados do presente estudo revelaram ainda que, a diminuição da intensidade da voz com o uso do amplificador, não foi suficiente para diminuir estatisticamente a f0 das participantes.
