It is known that vocal cool-down may contribute towards smoothing muscle fatigue after singing, however, there are still few studies about this practice among these professionals. Purpose: To verify the influence of vocal cool-down time on the symptoms of vocal tract discomfort and acoustic and perceptual voice parameters in a group of popular singers. Methods: it is a transversal and interventional study. The sample consisted of a group of popular singers randomly allocated in two groups according to the time of execution of vocal cool-down exercises: G5 (5 minutes) and G10 (10 minutes). Acoustic, auditory-perceptual and self-assessment through the Vocal Tract Discomfort Scale (VTDS) were performed in the before and after vocal cool-down moments. Results: In G5, there was significant improvement of the shimmer local dB (AVQI), overall degree in sentences and vowel, and degrees of roughness, breathiness and tension of the sentences. In G10, the improvement occurred for the irritated throat symptom, jitter, overall degree, roughness and tension in the sentences and vowel. The vocal cool-down also promoted improvement in different acoustic and perceptual aspects regarding sex. Conclusion: The vocal cool-down promoted improvement in the vocal parameters of the popular singers of this study, regardless of the time in which it was performed. The women presented more positive results than the men after 5 minutes of vocal cool-down.Acesso AbertoCantoAcústicaAutoavaliaçãoVozQualidade da vozmasterThesisCNPQ::CIENCIAS DA SAUDE: FONOAUDIOLOGIA
