试验用递减法测定了蒙、汉族学生122例(蒙古族63例,汉族59例)纯音听觉绝对阈限,并绘制了听阈曲线。统计结果显示:蒙古族与汉族对多数频率声音的听阈无显著差异,不同性别之间听阈亦无显著差异。
The declination method was used to determine the absolute threshold of pure tone hearing of 122 Mongolian and Han students (63 cases of Mongolian and 59 cases of Han nationality), and the threshold curve was drawn. The statistical results show that there is no significant difference between Mongolian and Han nationality on the frequencies of most frequency sounds, and there is no significant difference in hearing threshold between different genders.
