Influence of vocal and aerodynamics aspects on the voice-related quality of life of older adults

Abstract The pursuit for quality of life urged a better understanding of aspects involved in ageing to minimize its consequences. Although many studies investigated older adults' voice, aspects affecting this population voice-related quality of life have not yet been explored. Objective To investigate how aerodynamics and vocal aspects are associated with voice-related quality of life in older adults. Methodology fifty-six older adults aged 60 years or above - 39 women and 17 men - were evaluated. The following procedures were performed: application of the Voice-Related Quality of Life (V-RQOL) protocol; vocal assessment, including auditory-perceptual and acoustic analysis, from which we obtained fundamental frequency (F 0 ), standard deviation of fundamental frequency (SDF 0 ), shimmer, amplitude perturbation quotient (APQ), jitter, pitch period perturbation quotient (PPQ), and harmonics to noise ratio (HNR); aerodynamic assessment using a spirometer; and maximum phonation time (MPT) for /a/, /s/, /z/ and number counting. Results older adults tend to present high V-RQOL scores. Among women, roughness, APQ, and HNR parameters were negatively correlated with V-RQOL, whereas F 0 was positively. We found no correlation between spirometry measurements and V-RQOL. MPT for /a/, /z/, and number counting was positively correlated with V-RQOL solely among men. Conclusion Vocal roughness and acoustic parameters have a negative impact on the quality of life of older women. Respiratory aspects related to the available air support for speaking affected the most the voice-related quality of life of older men.

Sintomas do trato vocal e índice de desvantagem vocal para o canto moderno em cantores evangélicos / Correlation between vocal tract symptoms and modern singing handicap index in church gospel singers

RESUMO Objetivo correlacionar os sintomas de desconforto do trato vocal e desvantagem de voz percebida em homens e mulheres cantores evangélicos. Método participaram 100 cantores evangélicos, 50 do gênero masculino e 50 do feminino. Todos os participantes responderam a dois questionários: Escala de Desconforto do trato vocal (EDTV) e o Índice de Desvantagem para o Canto Moderno (IDCM). Foi realizada a comparação entre os gêneros, tanto em relação aos sintomas do trato vocal como em relação aos índices de IDCM, por meio do teste Mann-Whitney. Para a correlação entre as respostas na Escala de Desconforto no Trato Vocal e IDCM, foi utilizado o teste de Correlação de Sperman (p<0,05). Resultados cantoras evangélicas apresentaram maior frequência e intensidade de sintomas de desconforto do trato vocal, bem como maior desvantagem vocal para o canto, quando comparadas aos cantores evangélicos. Considerando as respostas de todos os cantores, houve correlações positivas entre os sintomas de desconforto do trato vocal e a desvantagem vocal para o canto. Conclusão as percepções de desconforto em trato vocal e de desvantagem para o canto foram diferentes entre os cantores evangélicos do gênero masculino e feminino no grupo estudado. O maior desconforto no trato vocal e desvantagem no canto foram verificados pelas cantoras. Quanto maior foi a frequência e a intensidade de sintomas de desconforto no trato vocal, maior foi a desvantagem vocal.

ABSTRACT Objective To verify the correlation between vocal tract discomfort symptoms and perceived voice handicaps in gospel singers, analyzing possible differences according to gender. Methods 100 gospel singers volunteered, 50 male and 50 female. All participants answered two questionnaires: Vocal Tract Discomfort (VTD) scale and the Modern Singing Handicap Index (MSHI) that investigates the vocal handicap perceived by singers, linking the results of both instruments (p<0.05). Results Women presented more perceived handicaps and also more frequent and higher intensity vocal tract discomfort. Furthermore, the more frequent and intense the vocal tract symptoms, the higher the vocal handicap for singing. Conclusion Female gospel singers present higher frequency and intensity of vocal tract discomfort symptoms, as well as higher voice handicap for singing than male gospel singers. The higher the frequency and intensity of the laryngeal symptoms, the higher the vocal handicap will be.
