Auditory brain stem responses evoked with click stimuli of varying repetition rates (11, 31, 51, and 91 clicks/sec) and intensities but judged as being equally loud as three reference loudness levels (90, 80, and 70 phons) were examined in normal-hearing listeners. Analysis of wave component latencies and amplitudes indicated that loudness level changes are reflected in the brain stem response. However, the combined influence of stimulus rate and intensity was greater than that of perceived loudness level. It was concluded that the auditory brain stem response does not provide a direct link to loudness perception.
在听力正常的受试者中，研究了由不同重复率（11、31、51和91次/秒）和强度的短声刺激诱发的听觉脑干反应，这些刺激的响度被判定与三个参考响度水平（90、80和70方）相同。对波成分潜伏期和波幅的分析表明，响度水平的变化反映在脑干反应中。然而，刺激率和强度的综合影响大于感知响度水平的影响。研究得出结论，听觉脑干反应与响度感知之间不存在直接联系。
