一组正常（非临床）的听众在安静的环境中和不同水平的背景噪声中，确定了最舒适的纯音听力水平和舒适听力水平的范围。一般来说，最舒适的听力（mcl）水平轮廓具有中等响度水平下的等响轮廓的一般形状-在中频处的最低强度和在低频处的最高强度。在安静的背景下，被认为是“舒适”的听力水平范围从最低频率的约20分贝到中频的约35分贝不等。mcl的可变性在高频处比在低频处更大，并且其与异声等响匹配的可变性的幅度大致相同。噪音的影响主要是提高舒适听力水平范围的下限，其次是提高上限。因此，舒适的听力水平的范围是下降...
The most comfortable listening level and the range of comfortable listening levels for pure tones were determined for a group of normal (nonclinical) listeners in the quiet and against various levels of background noise. In general, the most comfortable listening (mcl) level contour has the general shape of the equal‐loudness contour at intermediate loudness levels—lowest intensity at the middle frequencies and highest intensity at the lower frequencies. The range of listening levels considered “comfortable” against a quiet background varies from about 20 db at the lowest frequencies to about 35 db at the middle frequencies. The variability of the mcl is larger at high frequencies than at low frequencies, and it is about the same magnitude as the variability of heterophonic equal‐loudness matches. The effect of noise is primarily to raise the lower limit of the range of comfortable listening levels and only secondarily to raise the upper limit. As a result, the range of comfortable listening levels is dec...
