Introdução: Em Terapia da Fala são poucas as pesquisas a nível mundial acerca da qualidade vocal de coralistas amadores, sendo estas inexistentes em Portugal. No entanto, esta é uma população em que faz todo o sentido o trabalho de prevenção da saúde vocal uma vez que, embora não de forma profissional, é uma população que faz uso da voz cantada numa atividade relativamente constante, intensa e de qualidade.
Objetivo: Estabelecer padrões acústicos da voz em coralistas amadores segundo diferentes variáveis e determinar se o coro é benéfico para a qualidade vocal dos indivíduos.
Método: Participaram 31 coralistas de dois coros amadores da cidade do Porto, com idades compreendidas entre os 18 e os 78 anos, que responderam a um questionário com questões acerca de dados pessoais, caracterização do grupo e de alguns hábitos vocais. Foram avaliadas as medidas de desempenho – Tempos Máximos de Fonação das vogais /a/, /i/ e /u/ e Coeficiente s/z – e medidas acústicas. Foi utilizado o software PRAAT para recolher as medidas acústicas. Procedeu-se à análise estatística através do programa SPSS versão 17.0, segundo as variáveis sexo, faixa etária, naipe, tempo de frequência do coro, formação vocal extra-coro e hábitos tabágicos. Analisaram-se, para cada uma das medidas, a média, o desvio padrão e os extremos (mínimos e máximos).
Resultados: Pessoas que frequentam o coro há mais tempo manifestaram melhores resultados nas medidas observadas. Coralistas com formação de canto apresentaram padrões de qualidade vocal mais próximos do normal. Não foi possível concluir acerca da influência dos hábitos tabágicos nas medidas utilizadas. A queixa vocal mais referida foi a perda de voz e os hábitos vocais nocivos mais citados foram “falar muito” e “com forte intensidade”.
Conclusão: Integrar um grupo coral apresenta-se como uma mais-valia do ponto de vista da qualidade vocal, sendo que os coralistas poderiam beneficiar de um trabalho conjunto com a Terapia da Fala na vertente de prevenção e saúde da voz, atendendo às queixas frequentes inerentes ao abuso/mau uso desta.
Introduction: In Speech Therapy there is little research worldwide concerning the vocal quality of amateur choir singers, being there none in Portugal. Regardless, the intervention from this field of work with that population makes total sense once it uses singing voice as a relatively constant and intense activity with quality, although not in a professional way. Objective: Establish acoustic patterns of voice in amateur choristers according to different variables and determine if the choir is beneficial to the vocal quality of the individuals. Method: 31 choristers belonging to two different amateur choirs from the city of Porto, with ages between 18 and 78 years, participated in this study by answering a questionnaire about personal data, group characteristics and some vocal habits. Performance measures – Maximum Phonation Times of the /a/, /i/ and /u/ vowels and s/z Coefficient – and acoustic measures were evaluated. To gather the acoustic measures, the software PRAAT was used. The statistic analysis was done using the software SPSS version 17.0 according to the variables sex, age group, vocal group, time in the choir, vocal qualifications and smoking habits. For each of the measures, the mean, standard deviation, minimums and maximums were calculated. Results: People attending the choir for longer periods of time displayed better results in the observed measures. Choristers with vocal training showed patterns of vocal quality closer to normal. It wasn’t possible to verify the influence of smoking habits on the used measures. The most frequent vocal complaint was loss of voice and the more quoted noxious vocal habits were excessive and loud talking. Conclusion: Taking part at a choir is shown to be an asset from the vocal quality’s point of view, being that the choristers could benefit from a joint work with Speech Therapy concerning vocal health and prevention, attending the frequent complaints associated with abusive or bad use of the voice.
