To extinct to a great extent the methodic faults (rhythm) at the common way of the measurement of the difference-limen of intensity, the original parameter (the intensity) is randomized. The patient himself has to find out the minimal hearable modulation at this intensity. The testing-signal is interrupted in a rhythm of 0.8 cps, so that the effects of adaptation are reduced to a great extent. This test was carried out on 20 normal-hearing persons; 13 of them also were examined with a continuous tone; by this continuous tone the difference-limen of intensity was significantly reduced (p less than 1%).
为了在很大程度上消除强度辨别阈常规测量方法中的系统性误差（节奏），对原始参数（强度）进行随机化处理。患者必须自己找出在此强度下可听见的最小调制。测试信号以0.8赫兹的节奏中断，从而在很大程度上降低适应效应。对20名听力正常的人进行了此项测试；其中13人还用连续音进行了检查；通过这种连续音，强度辨别阈显著降低（p小于1%）。
