- W3157452952 abstract "Introduction Many vocal enhancement and rehabilitation programs for voice professionals define vocal exercises without analyzing their effects on that specific population in which they will be applied, in the established dose and often without considering the presence and absence of vocal alteration. Journalists have sought the voice clinic due to new professional vocal demands and a vocal program is being elaborated. Objective To determine the immediate effect of humming in professionals with and without voice disorders who work under high vocal demand in a journalistic context. Method Thirty-six individuals who completed the Dysphonia Risk Screening Protocol and underwent voice recording participated in the study. Three speech therapists defined the presence and/or absence of vocal changes by consensus. Subsequently, five repetitions of humming were proposed; the exercises lasted five seconds each and were separated by five seconds of complete silence, and recordings were made before and after the exercise (vowel and phrase). For the pre and post comparison between the groups with and without vocal changes, acoustic measurements and spectrogram, including the classification of the signal type, were performed. Results: The sample had a similar distribution of men and women and a mean age of 39.9 years. Most of the professionals were journalists or reporters. The risk of dysphonia was high for half of the sample, and the presence of vocal changes, predominantly mild ones, was identified in 56%. After the exercise, a decrease in noise at low frequencies and an improvement in the series of harmonics and the signal type were observed in both groups; a decrease in irregularity was observed only in the participants without vocal changes. Conclusion. The proposed humming exercise had an immediate positive effect on the voice of professionals working in a journalistic context, and the changes were particularly evident in aspects of the voice that were initially altered." @default.
