The present study aimed to vocally assess a group of rock singers who use growl voice and reinforced falsetto.
A group of 21 rock singers and a control group of 18 pop singers were included. Singing and speaking voice was assessed through acoustic, perceptual, functional and laryngoscopic analysis.
No significant differences were observed between groups in most of the analyses. Acoustic and perceptual analysis of the experimental group demonstrated normality of speaking voice. Endoscopic evaluation showed that most rock singers presented during singing voice a high vertical laryngeal position, pharyngeal compression and laryngeal supraglottic compression. Supraglottic activity during speaking voice tasks was also observed. However, overall vocal fold integrity was demonstrated in most of the participants. Slightly abnormal observations were demonstrated in few of them. Singing voice handicap index revealed that the most affected variable was the physical sphere, followed by the social and emotional spheres.
Although growl voice and reinforced falsetto represent laryngeal and pharyngeal hyperfunctional activity, they did not seem to contribute to the presence of any major vocal fold disorder in our subjects. Nevertheless, we cannot rule out the possibility that more evident vocal fold disorders could be found in singers who use these techniques more often and during a longer period of time.
本研究旨在对一组使用喉音和强化假声的摇滚歌手进行嗓音评估。
纳入一组21名摇滚歌手和一组18名流行歌手作为对照组。通过声学、感知、功能和喉镜分析对歌唱和说话嗓音进行评估。
在大多数分析中，两组之间未观察到显著差异。实验组的声学和感知分析表明说话嗓音正常。内镜评估显示，大多数摇滚歌手在歌唱时呈现高垂直喉位、咽部压缩和喉上声门压缩。在说话嗓音任务中也观察到声门上活动。然而，大多数参与者的声带整体完整性良好。少数参与者有轻微异常表现。歌唱嗓音障碍指数显示，受影响最大的变量是身体领域，其次是社会和情感领域。
尽管喉音和强化假声代表喉和咽部的功能亢进活动，但在我们的研究对象中，它们似乎并未导致任何主要的声带疾病。然而，我们不能排除在更频繁且更长时间使用这些技术的歌手中发现更明显声带疾病的可能性。
