"Voz metálica: estudo das características fisiológicas e acústicas" / Metallic voice : physiological and acoustic featuresHanayama, Eliana Midori 25 March 2003 (has links)
A presente pesquisa analisou, pelos aspectos fisiológicos e acústicos, a voz metálica visando sua compreensão. Vinte e um cantores profissionais foram avaliados com nasofaringolaringofibroscopia, emitindo a vogal /e/ no modo oral e metal. Avaliaram-se imagens da velofaringe, faringe e laringe e analisaram-se acusticamente as amostras vocais. Na voz metálica não houve mudança significativa de freqüência nem de amplitude de F1; houve aumento significativo de amplitude de F2, F3 e F4 e de freqüência de F2; voz metálica mais forte foi correlacionada significativamente com elevação de amplitude de F3 e F4; observaram-se ajustes consistentes do trato vocal tais como abaixamento velar, medialização de paredes faríngeas, elevação laríngea, constrição ariepiglótica e lateral / Metallic voice was studied by means of physiological and acoustical analyses in order to understand its production. Fiberscopic video pharyngolaryngoscopy was performed on 21 professional singers while speaking vowel /e/ in normal and metallic modes to observe muscular movements and structural changes of the velopharynx, pharynx and larynx, Vocal samples were acoustically analyzed. There were no significant changes in frequency and amplitude of F1 in metallic voice; there were significant increases in amplitudes of F2, F3 and F4 and in frequencies for F2; metallic voice perceived as louder was correlated to increase in amplitude of F3 and F4; vocal tract adjustments like velar lowering, pharyngeal wall narrowing, laryngeal raising, aryepiglottic and lateral laryngeal constriction were frequently found
