Características da fonetografia em mulheres com equilíbrio dentofacial

Abstract: RESUMOObjetivo: Caracterizar o perfil da extensão vocal de mulheres com equilíbrio dentofacial, por meio da fonetografia. Métodos:Fizeram parte desse estudo 22 estudantes do gênero feminino, com idades entre 18 e 29 anos ( -X = 20±2 anos), falantes do Português Brasileiro, sem alteração ou treino vocal, que apresentaram tipo de face padrão I e harmonia dento-oclusal. Foi aplicado um formulário específico de auto-resposta e também foi realizada avaliação antropométrica da face, avaliação dento-oclusal, exame da… Show more

“…Regarding the minimum frequency measurements, the averages were found to be approximate between the groups, agreeing with what was observed in another research on vocal range profile in elderly women, using phonetography, whose average result was of 154 Hz 18 . Such values are inferior to those found in young women population, whose average was of 167.32 Hz in women aged from 18 to 29 years 19 . It is possible that the farther reach towards lower frequencies occurred due to the lowering of frequency, commonly found in old age women.…”

“…As for the vocal range area, this study presented an average of 3.74% and 3.62%, respectively, in elderly women with and without voice symptoms, which is considered as reduced in relation to the vocal range area of adult women 19 , as expected, considering the vocal changes commonly found in old age individuals.…”

“…In this study, the F 0 values obtained for the female singers in both groups were similar to the reference values (9,10) , so it is possible to state that the metallic voice quality cannot be considered to be the voice pattern of high F 0 . However, the acute pitch sensation attributed to it is a result of the increasing frequencies and amplitudes of the formants (2) .…”

“…Considering the average values obtained for the minimum and maximum intensity (I MIN =66dB±3dB and I MAX =114dB±5dB), the values were similar to those of two other studies (I MIN =66±3,48dB and I MAX =118±2,62dB) 14 and (I MIN =67,6±2,41dB and I MAX =115,5±3,84dB) 23 , but were higher than others (I MiN =46,6dB±5,74dB and I MaX =100,3dB±5,57dB) 9 , (I MiN =46,2±0,4dB and I MAX =95,4±3,7dB) 8 and (I MiN =50,9dB and I MAX =97,3dB) 6 indicating that the presence of dentofacial equilibrium can facilitate not only the articulation of the headphones, but also the phonation process, allowing to reach higher maximum and minimum intensities, through increased air pressure during phonation, as well as better laryngeal control of the passage of air current 30,31 . However, such hypotheses should be tested in future studies, by comparing groups of individuals with dentofacial balanced condition to those with dentofacial deformities.…”
