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.
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).
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.
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.
比较 COVID-19 大流行期间专业和业余歌手对发声疲劳的自我感知以及在这段时间内对发声的使用，并将这种自我感知与这段时间内的发声使用特点联系起来。
共有 121 名歌手参与了这项研究，分为专业歌手组（PSG）（12 名男性和 20 名女性）和业余歌手组（ASG）（37 名男性和 52 名女性）。PSG 组由仅依靠歌唱作为职业的歌手组成，ASG 组由不完全依靠歌唱维持生计的歌手组成。所有参与者均通过 Google Forms®在线回答问卷。在大流行之前和期间，调查了他们的社会人口学和发声特征；通过发声疲劳指数（VFI）评估发声疲劳症状；通过巴西简易发声评估协议（EASE-Br）评估对发声的自我感知。
在组间比较中，PSG 在疲劳和发声受限（P=0.045）、发声受限（P=0.002）和休息后恢复（P=0.008）等领域的发声疲劳评分高于 ASG。两组在对发声的使用上没有差异。基于大流行期间自我感知和发声使用特点之间的关系，观察到发声投诉的存在是两组中与疲劳症状自我感知相关的唯一因素。关于当前歌唱状态的自我感知，歌唱时间、发声投诉的存在、增加视觉注意力的需求以及对大流行期间发声恶化的感知，被认为是业余歌手的预测因素。对于专业歌手，发声投诉和发声训练是自我感知当前歌唱状态的预测因素。
专业歌手的发声疲劳评分高于业余歌手。两组的发声疲劳症状均与发声投诉的存在有关。然而，歌唱的当前状态的自我感知在两组之间有所不同，与专业歌手的发声训练以及业余歌手在大流行期间对歌唱发声需求的特点有关。
