可接受噪声水平(ANL)通过从最舒适的听力水平(ANL = 、MCL、 − BNL)中减去背景噪声水平(BNL)来定义。本研究比较了20名听力正常的中国受试者不同方法测得的ANL。ANL用扬声器或耳机用普通话语音材料进行测试，每个受试者都由他自己或由听力专家测试。呈现和响应模式如下：(1)具有使用听力计控制的自我调节噪声水平的扬声器(LS方法)；(2)具有受试者的扬声器，其向听力学家发出信号以调整语音和噪声水平(LA方法)；(3)具有使用听力计控制的自我调节噪声水平的耳机(ES方法)；以及(4)具有受试者以信号向听力学家发出信号以调节语音和噪声水平的耳机(EA方法)。每种方法通过三次测量计算ANL。不同呈现方式或不同反应方式获得的ANL差异无统计学意义。两种方法测得的ANL、MCL和BNL之间均有显著相关性。总之，听力正常的普通话听者的ANL可能不会受到扬声器或耳机等呈现方式的影响，也不会受到自我调整或听觉学家调整的反应模式的影响。耳机测听与声场测听一样可靠，提供了一种简便的测量ANL的方法。
The acceptable noise level (ANL) was defined by subtracting the background noise level (BNL) from the most comfortable listening level (MCL) (ANL = MCL − BNL). This study compared the ANL obtained through different methods in 20 Chinese subjects with normal hearing. ANL was tested with Mandarin speech materials using a loudspeaker or earphones, with each subject tested by himself or by the audiologist. The presentation and response modes were as follows: (1) loudspeaker with self-adjusted noise levels using audiometer controls (LS method); (2) loudspeaker with the subject signaling the audiologist to adjust speech and noise levels (LA method); (3) earphones with self-adjusted noise levels using audiometer controls (ES method); and (4) earphones with the subject signaling the audiologist to adjust speech and noise levels (EA method). ANL was calculated from three measurements with each method. There was no significant difference in the ANL obtained through different presentation modes or response modes sound. The correlations between ANL, MCL, and BNL obtained from each two methods were significant. In conclusion, the ANL in normal-hearing Mandarin listeners may not be affected by presentation modes such as a loudspeaker or earphones nor is it affected by self-adjusted or audiologist-adjusted response modes. Earphone audiometry is as reliable as sound field audiometry and provides an easy and convenient way to measure ANL.
