Normal-hearing (N:20) and sensorineural adults (N:15) performed sweep-frequency Bekesy audiometry from .1-8 kc/s at threshold and at MCL and UCL with both continuous (C) and interrupted (I) tones. Excursion width was measured in 1-db steps. Normals exhibited no C-I differences in excursion width at any level, and differences between the two groups of Ss were negligible for I tones, but the sensorineural Ss yielded significantly smaller widths at 3, 4 and 6 kc/s for C tones at both suprathreshold levels. SInce a number of sensorineural Ss did not yield tracings at UCL, it was recommended that MCL be traced as one feature of site-of-lesion testing. Of the sensorineurals, 75% yielded widths of 5 db or less for C tones at MCL, and this criterion in a sweep-frequency Bekesy is suggested as of clinical value.
听力正常的成年人（N = 20）和感音神经性耳聋的成年人（N = 15）在阈值、舒适响度级（MCL）和不舒适响度级（UCL）下，使用连续音（C）和断续音（I）进行了0.1 - 8千周/秒的扫频Bekesy听力测验。以1分贝的步长测量偏移宽度。正常受试者在任何水平下的偏移宽度在连续音和断续音之间均无差异，两组受试者在断续音下的差异可忽略不计，但感音神经性耳聋的受试者在两个阈上水平下，对于连续音，在3千周/秒、4千周/秒和6千周/秒时的偏移宽度显著更小。由于一些感音神经性耳聋的受试者在不舒适响度级下未得出描记图，建议将舒适响度级的描记作为病变部位测试的一个特征。在感音神经性耳聋的受试者中，75%在舒适响度级下连续音的偏移宽度为5分贝或更小，扫频Bekesy听力测验中的这一标准被认为具有临床价值。
