Musical theater performers are a special group of elite vocal performers with a high vocal load as they combine singing, acting, and physical performance. As they are absolutely depending on their voice quality and vocal capacities for their studies and their future profession, an optimal voice production is very important. The purpose of this study was to determine the voice quality of musical theater students. The voice quality of seven students was then reevaluated 1 year after the first assessment.
Observational study.
Thirty-one musical students (7 men and 24 women) with a mean age of 20 years participated in the study. To determine the voice quality, objective (aerodynamic measurements, voice range profile, acoustic analysis, and Dysphonia Severity Index) and subjective (videolaryngostroboscopy, Voice Handicap Indexes, and questionnaires regarding voice symptoms and risk factors) voice measurements were performed.
The median Dysphonia Severity Index in male and female musical students was respectively 5.3 and 5.7, both corresponding with an overall good voice quality. The questionnaires revealed the presence of vocal fatigue, dryness of the throat, vocal tract discomfort, and harmful vocal habits in the majority of students. In 45% of the subjects, videolaryngostroboscopic evaluation of the vocal folds showed an organic lesion. The majority of these lesions are inflammatory lesions (26%). In 68% of the subjects, a certain degree of supraglottic constriction was observed.
Despite the overall good voice quality, videolaryngostroboscopy showed a high presence of vocal fold lesions and supraglottic constriction during phonation.
音乐剧表演者是一群特殊的精英声乐表演者，由于他们要将唱歌、表演和肢体表现结合起来，所以嗓音负荷很高。因为他们的学业和未来职业完全依赖于嗓音质量和发声能力，所以优化发声非常重要。本研究的目的是确定音乐剧专业学生的嗓音质量。在首次评估1年后，对7名学生的嗓音质量进行了重新评估。
观察性研究。
31名音乐专业学生（7名男性和24名女性）参与了该研究，平均年龄为20岁。为了确定嗓音质量，进行了客观（空气动力学测量、嗓音音域图、声学分析和嗓音障碍严重指数）和主观（视频喉镜频闪检查、嗓音障碍指数以及关于嗓音症状和风险因素的问卷调查）嗓音测量。
男性和女性音乐专业学生的嗓音障碍严重指数中位数分别为5.3和5.7，均对应总体良好的嗓音质量。问卷调查显示，大多数学生存在嗓音疲劳、喉咙干燥、声道不适和有害的发声习惯。在45%的受试者中，视频喉镜频闪检查声带显示有器质性病变。这些病变大多数是炎症性病变（26%）。在68%的受试者中，观察到一定程度的声门上狭窄。
尽管总体嗓音质量良好，但视频喉镜频闪检查显示发声时声带病变和声门上狭窄的发生率很高。
