Abstract

The harmonic components in hoarse voice were separated from the noise components by using a small laboratory computer. The ratio of harmonics to noise or S/N ratio, was calculated and compared with the auditory impression for 58 subjects. The calculated results showed a definite correlation to the auditory impression, and it is suggested that this would be a useful method for the quantitative evaluation of hoarseness.

摘要

利用一台小型实验室计算机将嗓音嘶哑中的谐波成分与噪声成分分离。计算谐波与噪声的比率即信噪比，并与58名受试者的听觉印象进行比较。计算结果显示与听觉印象有明确的相关性，并且表明这将是一种用于嗓音嘶哑定量评估的有用方法。
