30 female teachers of ten-years technical schools-15 with functional voice-disturbance an 15 with healthy voice-have been examined while teaching in respect of their strain. Duration of speech, intensity of their teachers voice an background noise, the frequency of heart rate and the arterial blood pressure were measured on the teaching day. Between both research groups no statistically significant differences were shown. There were no correlations between the durations of speech, intensity and vegetative parameters.
对30名十年制技术学校的女教师进行了研究——其中15名有功能性嗓音障碍，15名嗓音健康。在她们授课时对其疲劳程度进行了检查。在授课当天测量了她们的讲话时长、教师嗓音强度和背景噪音、心率频率以及动脉血压。两个研究组之间未显示出统计学上的显著差异。讲话时长、强度与自主参数之间没有相关性。
