In this report we present one example of the utilization of an acoustic measurement to aid in describing voice roughness objectively in a clinical context. Vowel spectral noise level (SNL) and fundamental voice frequency (F0) measurements were acquired for five sustained vowels produced by one patient having bilateral vocal fold nodules. The measurements were obtained at specific time intervals while the patient underwent voice therapy. Clinically observed changes over the course of therapy included an improvement in perceived voice quality, a general reduction in vowel SNL, and an increase in vowel F0. These observations were accompanied by visually detected laryngeal tissue changes. The results suggest that acoustic SNL measurements can be employed clinically to verify and support perceptual judgments of voice quality.
在本报告中，我们展示了一个利用声学测量来辅助在临床环境中客观描述嗓音粗糙程度的例子。对一名患有双侧声带小结的患者发出的五个持续元音进行了元音频谱噪声水平（SNL）和基音频率（F0）测量。在患者接受嗓音治疗期间，于特定时间间隔进行测量。治疗过程中临床观察到的变化包括嗓音质量的改善、元音SNL的普遍降低以及元音F0的增加。这些观察结果伴随着肉眼检测到的喉部组织变化。结果表明，声学SNL测量可在临床上用于验证和支持对嗓音质量的感知判断。
