• W4382024215 abstract "To compare the results of the non-linear acoustic analysis of elderly male and female voices, speakers of Brazilian Portuguese.Recordings of 14 men and 15 women were used. The voices were consensually judged to be vocally healthy by three trained speech therapists. The non-linear acoustic analysis was performed by the Phase Space Reconstruction (PSR) analysis using the Voice Analysis program.A significant difference was observed in the parameter irregularity (p = 0.001) and spacing (p = 0.005), with worse results for the male group. While 93% of male voices presented degrees 2 or 3 of irregularity, these degrees were observed in 53% of female voices. In 78.6% of male voices, medium to large spacing was observed, a fact observed only in 26.7% of women.The results of the non-linear analysis, through the Phase Space Reconstruction, using the CIS Protocol, in the voices of the elderly, showed the best result in terms of the number of curves (four or more). Regarding the irregularity of the tracing, in men, the majority presented grades 2 and 3 and in women, half presented grade 1. Regarding the spacing, 78.6% of the male voices had medium to large spacing, a fact observed only in 26.7% of women.There was a difference between the sexes in the vocal findings of the elderly by the CIS protocol with the PSR, pointing out worse results irregularity and spacing in the male population, which suggests greater vocal aperiodicity in elderly men.Verificar medidas acústicas das vozes de idosos pela análise não linear e realizar a comparação entre os sexos.Participaram 29 idosos, falantes do Português Brasileiro, vocalmente saudáveis: 14 homens e 15 mulheres. Todas as vozes foram julgadas como vocalmente saudáveis por três fonoaudiólogas treinadas, por meio de avaliação perceptivo-auditiva. A análise acústica não linear foi realizada pela análise da Reconstrução de Espaço de Fase utilizando o programa Análise de Voz.Foi observado diferença significativa no parâmetro irregularidade (p=0,001) e espaçamento (p=0,005) entre os sexos, com resultados piores no grupo masculino. Enquanto 93% das vozes masculinas apresentaram graus 2 ou 3 de irregularidade, estes graus foram observados em 53% das vozes femininas. Em 78,6% das vozes masculinas foi observado espaçamento de médio a grande, fato observado somente em 26,7% das mulheres.Os resultados da análise não linear, por meio da REF, com a utilização do protocolo CIE, em vozes de idosos, mostraram o melhor resultado quanto ao número de curvas (quatro ou mais). Em relação à irregularidade do traçado, nos homens, a maioria apresentou graus 2 e 3 e nas mulheres, a metade apresentou grau 1. Relativo ao espaçamento, 78,6% das vozes masculinas foi observado espaçamento de médio a grande, fato observado somente em 26,7% das mulheres. Houve diferença entre os sexos nos achados vocais de idosos pelo protocolo CIE com a análise de Reconstrução de Espaço de Fase, apontado piores resultados na irregularidade e espaçamento na população masculina, o que sugere maior aperiodicidade vocal em homens idosos." @default.
