Abstract

Voice production is a complex multidimensional phenomenon resulting from the combination of acoustic, aerodynamic and elastic forces. The evaluation of voice characteristics in clinical practice is often based only on perceptual and acoustic evaluation, but an exhaustive assessment should take into consideration also aerodynamic parameters. In this study two groups of subjects, the first one composed by patients affected by organic dysphonia and the second one by controls with normal voice, underwent: simultaneous acoustic/aerodynamic voice assessment by means of EVA device (SQ-Lab, Aix-en-Provence, F); maximum phonation time measurement; GIRBAS perceptual evaluation. Statistical analysis allowed to search for correlations between the perceptual voice quality grading and the recorded acoustic/aerodynamic parameters.
