Abstract:
To date, no established protocol exists for measuring functional voice changes in singers with subclinical singing-voice complaints. Hence, these may go undiagnosed until they progress into greater severity. This exploratory study sought to (1) determine which scale items in the self-perceptual Evaluation of Ability to Sing Easily (EASE) are associated with instrumental voice measures, and (2) construct as proof-of-concept an instrumental index related to singers\' perceptions of their vocal function and health status. Eighteen classical singers were acoustically recorded in a controlled environment singing an /a/ vowel using soft phonation. Aerodynamic data were collected during a softly sung /papapapapapapa/ task with the KayPENTAX Phonatory Aerodynamic System. Using multi and univariate linear regression techniques, CPPS, vibrato jitter, vibrato shimmer, and an efficiency ratio (SPL/PSub) were included in a significant model (p < 0.001) explaining 62.4% of variance in participants\' composite scores of three scale items related to vocal fatigue. The instrumental index showed a significant association (p = 0.001) with the EASE vocal fatigue subscale overall. Findings illustrate that an aeroacoustic instrumental index may be useful for monitoring functional changes in the singing voice as part of a multidimensional diagnostic approach to preventative and rehabilitative voice healthcare for professional singing-voice users.
摘要:
迄今为止,目前尚无既定的协议来测量具有亚临床歌唱声音主诉的歌手的功能性声音变化。因此,这些可能无法诊断,直到他们发展到更严重。这项探索性研究旨在(1)确定自我感知评估中的哪些量表项目轻松唱歌(EASE)与乐器语音测量相关,(2)构建与歌手对其声音功能和健康状况的感知相关的工具指数作为概念证明。在受控环境中,使用柔和的声音演唱了18位古典歌手的声音。在使用KayPENTAX语音空气动力系统进行轻唱/papapapapapapa/任务期间收集了空气动力学数据。使用多元和单变量线性回归技术,CPPS,颤音抖动,颤音闪烁,和效率比(SPL/PSub)被纳入一个显著模型(p<0.001),解释了与声带疲劳相关的三个量表项目的参与者综合评分的62.4%的方差。总体上,仪器指数与EASE声带疲劳分量表具有显着相关性(p=0.001)。研究结果表明,作为针对专业唱歌用户的预防和康复语音保健的多维诊断方法的一部分,空气声学仪器指数可用于监测唱歌声音的功能变化。
