“…The aspects of the voice of the elderly in the NSG are in compliance with the literature, which describes a worsening of the vocal quality with aging (1,3) . These findings corroborate research which indicates that choral singing can help promoting vocal health and preventing vocal aging (15,16,18,19,(21)(22)(23)(24) . Specifically for vocal strain, statistical analysis of the terciles shows that the results presented two directions ( Table 4).…”

“…The first direction corresponds to the second tercile (1.9 to 3.0 cm), which represents typical voices, as proposed by Yamasaki et al (29) . This tercile showed higher proportion for the SG (50%) compared with the NSG (8%), which may be related to the increased laryngeal control of singers, who need to adjust their the vocal tracts to produce the singing voice, as suggested by some authors (19) . The second direction corresponds to the third tercile (3.1 to 5.2 cm), a score similar to that suggested by Yamasaki et al (29) (3.5 to 5.0 cm), which represents the presence of light-to-moderate change.…”

“…Therefore, it can be inferred that choral singing motivates and encourages the elderly to be more active physically and socially, which can influence their vocal quality. It may also be appropriate to think distinctively, that is, the most active elderly individuals are the ones who engage in various activities for the opportunity of relating (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22) . The other aspects related to habits (throat clearing, coughing, speaking loudly, and shouting) and vocal signs (difficulty and fatigue) account for less than a third of the occurrences, and no significant differences were found in the comparison between the groups (Tables 1 and 2).…”

“…Research indicates that choral singing can also help promoting the vocal health of the elderly population (15)(16)(17)(18)(19)(20)(21) , mainly because this practice provides guidance on the habits that are harmful to vocal health and discourages individuals from having them, encouraging healthy habits. For example, the intense vocal demand of choral singing encourages increased water consumption, which is considered a health promotion measure because it prevents the wear of laryngeal structures.…”

RESUMO Introdução Apesar dos vários estudos relacionados à voz na terceira idade e o canto, ainda são necessárias pesquisas que busquem entender os efeitos dessa prática na voz falada de idosos. Objetivo comparar as características da voz falada de idosas com prática de canto coral às de idosas sem essa vivência. Método fizeram parte deste estudo 75 idosas, sendo 50 com prática de canto coral que compuseram o grupo corista (GC) e 25 sem essa prática (GNC), que foram comparadas. Para caracterização das idosas e levantamento de dados referentes aos hábitos de vida e voz, foi aplicado um questionário. Foram coletadas amostras de fala (vogal sustentada, repetição de frases e um trecho de fala espontânea) em uma sala silenciosa com as idosas sentadas. As vozes foram analisadas por três juízes fonoaudiólogos segundo o protocolo Consensus Auditory–Perceptual Evaluation of Voice (CAPE-V). Os dados foram submetidos à análise descritiva e estatística. Resultados as vozes das idosas do GNC apresentaram aumento significativo nos escores relacionados à alteração do grau geral e presença de rugosidade e tensão. Conclusão A análise das características da voz falada de idosas coristas, quando comparada a daquelas que não realizam essa prática, apontou para melhor qualidade vocal no aspecto geral, em decorrência de menor rugosidade e tensão.

“…Positional changes of the thyroid cartilage vary according to the singer's vocal timbre and intensity [22]. During singing, the trained singer combines physiological strategies including adjustments taking place between the respiratory, articulatory and laryngeal systems, which are different from the untrained singer [3].…”

Difficulty with singing is a rare but important complication following cervical spine surgery but there is little objective information regarding the cervical and head postural changes taking place during singing. The aim of this study was to identify postural changes in the cranio-cervical region associated with the demands of voice production in professional opera singing. The two Roentgen-cephalograms, one of which are taken whilst performing a specified singing task were taken from 18 professional opera students, 12 females (mean age 20.86 ± 3.07 years) and six males (18.66 ± 1.36 years). A paired t test compared mean cranio-cervical postural and pharyngeal/hyoid variables between the two registrations (P = 0.05). The association between the craniocervical postural variables and the pharyngeal/hyoid region in each registration position was examined using Spearman's rank correlation coefficient. In singing, the position of the atlas with respect to the true vertical (P \ 0.001), the axis (P \ 0.001) and the C4 vertebra both with respect to the horizontal (P \ 0.001), and the axis with respect to the cranium (P \ 0.001), were all significantly different to those at rest. Of the cranio-cervical postural variables in the singing registration, the angles measuring positional change of the atlas and C4 relative to the true horizontal were shown be significantly related to an increased pharyngeal airway space at the C3 level (P \ 0.01). An appreciation of the requirement for the cervical spine to undergo postural change during professional opera singing has relevance to the potential impact on voice quality in professional opera singers should they undergo cervical spine surgery.

Objective Determine the permeability of excised canine vocal fold lamina propria Study Design Basic Science Methods Vocal folds were excised from canine larynges and mounted within a device to measure the flow of 0.9% saline through the tissue over time. The resultant fluid volume displaced over time was then used in a variation of Darcy’s law to calculate the permeability of the tissue. Permeability was found through each anatomical plane of the vocal fold, with 5 samples per plane. Permeability was also found for lamina propria stretched to 10%, 20%, and 30% of initial length to determine the effects of tensile strain on permeability, with 5 samples per level of strain. Results Permeability was found to be 1.40×10−13 m3s/kg through the sagittal plane, 1.00×10−13 m3s/kg through the coronal plane, and 4.02×10−13 m3s/kg through the axial plane. It was significantly greater through the axial plane than both the sagittal (p=0.025) and coronal (p=0.009) planes. Permeability under strain through the sagittal plane was found to be 1.94×10−13 m3s/kg under 10% strain, 3.35×10−13 m3s/kg under 20% strain, and 4.80×10−13 m3s/kg under 30% strain. The permeability significantly increased after 20% strain (p<0.05). Conclusion Permeability in canine vocal fold lamina propria was found to be increased along the anterior-posterior axis, following the length of the vocal folds. This may influence fluid distribution within the lamina propria during and after vibration. Similarly, permeability increased after 20% strain was imposed on the lamina propria, and may influence vocal fold dynamics during certain phonation tasks.
