This work ayms to study the perceptual evaluation and the acoustic analysis in 25
women. In this population, 20 women had vocal nodule and 5 had normal voices and larynx.
It was defined the vocal node as the interest pathology, which is a reaction to the excessive
use of the voice, that induces to the constant vocal folds movement. It was used VoxMetria
software to analise the acoustic data. This research was approved by Hospital Erasto Gaertner
Research and Ethics Commission, in Curitiba/ Paraná. The selected women were submitted to
3 evaluations: laryngological, perceptual and acoustic. In the larynx exam it was used the
“videolaringoestroboscopia”. In the perceptual evaluation it was used the RASAT scale. The
basic frequency parameters (f0), the noise measure GNE (glottal to noise excitation ratio) and
the vocal spectrogram, to the acoustic analysis, where it was used the supported vowel [é].
The results showed that the basic frequency values were more thick in the group with vocal
nodule and the noise measure GNE wasn’t sensitive in both group analysis and showed
normal results. The perceptual evaluation and the vocal spectrogram revealed significant
differences between the two groups. The vocal spectrogram were really sensitive when
compared to the perceptual evaluation |
