The test-retest reliability of Most Comfortable Loudness Level (MCL) was examined in three experiments using young normal-hearing adults unsophisticated in audiometric testing. Test stimuli included pure tones, narrow-band noise, and damped wave trains, with presentation by ascending, descending, and Bekesy procedures. Intersubject reliability was found to be very poor and intrasubject reliability to be only fair. Although instructions to Ss and subjects interpretation of instructions probably affect MCL reliability, the task appears to be inherently variable.
在三项实验中，对最舒适响度级（MCL）的重测信度进行了检验，实验采用听力正常的年轻成年人为受试者，他们对听力测试尚不熟练。测试刺激包括纯音、窄带噪声和阻尼波列，通过升序、降序和贝凯西程序进行呈现。发现受试者间信度非常低，受试者内信度仅为一般。虽然向受试者的指导语以及受试者对指导语的理解可能会影响MCL信度，但该任务似乎本质上就具有变异性。
