The interdependence of changes in mean fundamental frequency and mean phonatory sound level, before and after voice treatment, was studied in 22 female and 11 male patients suffering from nonorganic dysphonia. All patients read continuous texts at three different vocal loudness levels, and also while being exposed to a filtered noise. After the reading sessions, phonetograms were recorded. The female patients achieved a higher mean sound level during the speech test after therapy. By contrast, the male patients increased their mean fundamental frequencies less during noise exposure after therapy, while the female patients retained essentially the same mean fundamental frequencies afterwards. The female patients produced a significantly higher upper phonetogram contour after therapy, whereas the male patients lowered their lower phonetogram contour.
对22名女性和11名男性非器质性发声障碍患者在嗓音治疗前后平均基频变化与平均发声声级变化之间的相互依存关系进行了研究。所有患者在三种不同的发声响度水平下朗读连续文本，并且在暴露于过滤噪声的情况下朗读。朗读结束后，记录声谱图。治疗后，女性患者在言语测试中达到了更高的平均声级。相比之下，男性患者在治疗后噪声暴露期间平均基频增加较少，而女性患者之后基本保持相同的平均基频。治疗后，女性患者产生的声谱图上轮廓明显更高，而男性患者则降低了声谱图下轮廓。
