Abstract
OBJETIVO: definir medidas aerodinâmicas em falantes do português brasileiro, sem queixas vocais, obtidas pelo programa EVA. MÉTODO: participaram do estudo 20 homens e 20 mulheres, que tiveram suas vozes analisadas. RESULTADOS: os valores médios referentes à pressão subglótica para vozes femininas e masculinas foram, respectivamente: Pressão subglótica= 5,84 hPa e 6,7 hPa, média da intensidade= 79,21 dB e 81,7 dB, média do fluxo oral= 0,09 dm³/s e 0,16 dm³/s, eficiência glótica= 13,87 dB/hPa e 12,78 dB/hPa, eficiência laríngea= 188,08 dB/(hPa.dm³/s) e 97,11 dB/(hPa.dm³/s), resistência laríngea= 96,26 hPa/(dm³/s) e 52,64 hPa/(dm³/s), média da frequência fundamental (F0)= 208,28 Hz e 136,56 Hz e pico da pressão do fluxo oral= 0,093 e 0,098. Houve diferença estatisticamente significante em relação ao gênero para as medidas de média de intensidade, eficiência laríngea, resistência laríngea e média da frequência fundamental. Os valores médios referentes ao fluxo oral para vozes femininas e masculinas foram respectivamente: Pressão subglótica= 6,05 hPa e 6,6 hPa, média da intensidade= 65,50 dB e 66,3 dB, média do fluxo oral= 0,10 dm³/s e 0,13 dm³/s, eficiência glótica= 11,12 dB/hPa e 11,77 dB/hPa, eficiência laríngea= 144,83 dB/(hPa.dm³/s) e 97,89 dB/(hPa.dm³/s), resistência laríngea= 78,98 hPa/(dm³/s) e 61,81 hPa/(dm³/s), média da F0= 222,52 Hz e 139,20 Hz e pico da pressão do fluxo oral= 0,047 e 0,053. CONCLUSÃO: o EVA é um programa ainda novo no Brasil, e a análise de medidas aerodinâmicas, em falantes do português brasileiro, permite a obtenção de valores de referência, possibilitando assim comparações com estudos futuros.
PURPOSE: to define aerodynamic measures in Brazilian Portuguese speakers without voice complaints, obtained by the EVA program. METHOD: the study included 20 men and 20 women who had their voices analyzed. RESULTS: the mean values with subglottic pressure for female and male voices were: Subglottic pressure = 5.84 hPa and 6.7 hPa; average intensity = 79.21dB and 81.7dB; oral mean flow = 0.09 dm3/s and 0.16 dm3/s; glottic efficiency = 13.87dB/hPa and 12.78 dB/hPa; laryngeal efficiency = 188.08 dB/(hPa.dm3/s) and 97.11dB/(hPa.dm3/s); laryngeal resistance = 96.26 hPa/(dm3/s) and 52.64 hPa/(dm3/s); mean fundamental frequency (F0) = 208.28 Hz and 136.56 Hz and peak mouth pressure flow = 0.093 and 0.098. There was a statistically significant difference in relation to gender for the measures of average intensity, efficiency, larynx, laryngeal resistance and mean fundamental frequency. The average flow for the oral female and male voices were: subglottic pressure = 6.05 hPa and 6.6 hPa; average intensity = 65.50 dB and 66.3 dB; oral mean flow = 0, 10 dm3/s and 0.13 dm3/s; glottic efficiency = 11.12 dB/hPa and 11.77 dB/hPa; laryngeal efficiency = 144.83 dB/( hPa.dm3/s) and 97.89 dB/( hPa.dm3/s); laryngeal resistance = 78.98 hPa/(dm3/s) and 61.81 hPa/( dm3/s); average F0 = 222.52 Hz and 139.20 Hz and peak pressure oral flow = 0.047 and 0.053. CONCLUSION: EVA is a new program in Brazil, and analysing the aerodynamic measures in Brazilian Portuguese speakers, allows us to obtain reference values, thus allowing comparisons with future studies.
