The purpose of this study was to investigate vocal quality, vocal complaints, and risk factors for developing voice disorders in theater actors. Secondly, the impact of one vocal performance on the voice was investigated by comparing objective and subjective vocal quality before and after a theater performance.
Prospective study of the actors' voice prior to and after a performance METHODS: Speech samples of 26 theater actors (15 men, 11 women, mean age 41.9 years) were recorded before and after a theater performance of one and a half hour and analyzed using the software program Praat. Speech samples consisted of the combination of sustained phonation and continuous speech. For each speech sample, the Acoustic Voice Quality Index was calculated. Auditory perceptual evaluations were performed using the GRBASI scale. Questionnaires were used to inventory vocal symptoms and influencing factors.
Acoustic analysis showed a mean Acoustic Voice Quality Index (AVQI) of 3.48 corresponding with a mild dysphonia. Fifty percent of the theater actors reported having (sometimes or regularly) vocal complaints after a performance. The questionnaire revealed a high presence of vocally violent behavior and poor vocal hygiene habits. Objective vocal quality, measured by the AVQI, did not change after a theater performance. The auditory perceptual evaluation of the overall grade of dysphonia showed a subtle amelioration of the vocal quality.
The results of this study showed the presence of mild dysphonia, regular vocal complaints, and poor vocal hygiene habits in theater actors. A theater performance did not have an impact on the objective vocal quality.
本研究旨在调查戏剧演员的嗓音质量、嗓音问题及嗓音障碍的风险因素。其次，通过比较戏剧表演前后客观和主观嗓音质量，研究一次嗓音表演对嗓音的影响。
对演员表演前后的嗓音进行前瞻性研究
记录26名戏剧演员（15名男性，11名女性，平均年龄41.9岁）在一场半小时戏剧表演前后的语音样本，并使用Praat软件程序进行分析。语音样本包括持续发声和连续言语的组合。计算每个语音样本的声学嗓音质量指数。使用GRBASI量表进行听觉感知评估。通过问卷调查列出嗓音症状和影响因素。
声学分析显示，声学嗓音质量指数（AVQI）平均为3.48，对应轻度发音障碍。50%的戏剧演员表示表演后（有时或经常）有嗓音问题。问卷调查显示，存在大量嗓音暴力行为和不良嗓音卫生习惯。通过AVQI测量的客观嗓音质量在戏剧表演后没有变化。发音障碍总体等级的听觉感知评估显示嗓音质量有细微改善。
本研究结果表明，戏剧演员存在轻度发音障碍、经常出现嗓音问题以及不良嗓音卫生习惯。戏剧表演对客观嗓音质量没有影响。
