 我們关于青年人純音听觉阈限的測定工作的第二部分,卽現在所要报导的部分,是根据耳机在被試外耳听道中所产生的声压和耳机輸入电压之間的关系(这个关系称为人耳校准的耳机灵敏度)的測定,和工作的第一部分中原有的数据,包括各频率測試起点的耳机輸入电压,和达到听阈时的衰減数字等,計算出各...

The sensitivity of the earphones used in the hearing tests carried out by the Institute: of Psychology is determined by measuring the sound pressure produced by them both at the external. end of the meatus of the human ear and at the eardrum,' for which purpose a probe microphone is employed. From the earphone sensitivity data and the audiometric data the normal threshold of hearing for 9 differecent frequencies’(from 125 to 8Q00 inclusive) was obtained.

The threshold curves were compared with curves obtained by different authors abroad.
