Vocal Self-Perception of Singers During COVID-19 Pandemic.

Objective: to compare the self-perception of vocal fatigue and use of singing voice during the COVID-19 pandemic between professional and amateur singers and to relate this self-perception with vocal use characteristics during this period.

Methodology: Participants were 121 singers divided into professional singers group (PSG) (12 men and 20 women) comprising singers who depended exclusively on singing as a profession and an amateur singers group (ASG) (37 men and 52 women) of singers who did not depend exclusively on singing for their livelihood. All answered online questionnaires through Google Forms ®. Sociodemographic and vocal characteristics were investigated before and during the pandemic; symptoms of vocal fatigue were assessed through the vocal fatigue index (VFI); and self-perception of use of singing voice through the evaluation of the ability to sing easily protocol for Brazil (EASE-Br).

Results: In the comparison between groups, the PSG presented higher scores of vocal fatigue in fatigue and vocal limitation (P = 0.045), vocal restriction (P = 0.002), and recovery with vocal rest (P = 0.008) domains than did the ASG. There was no difference between the groups regarding the use of singing voice. Based on the relationship between self-perception and vocal use characteristics during the pandemic, it was observed that the presence of vocal complaint was the only factor associated with self-perception of fatigue symptomatology in both groups. Regarding the self-perception of the current status of the singing voice, singing time, the presence of vocal complaints, the need to increase visual concentration, and the perception of vocal worsening during the pandemic were considered predictive for amateur singers. For professional singers, vocal complaints and vocal training were predictors for self-perception of the current status of the singing voice.

Conclusion: Professional singers presented with higher scores of vocal fatigue than did amateur singers. The symptomatology of vocal fatigue was associated with the presence of vocal complaints in both groups. However, self-perception of the current status of the singing voice was different between the groups and was associated with vocal training for professional singers and characteristics of vocal demand of singing voice during the pandemic period for amateur singers.
