Discrete-frequency Bekesy HTLs (.25, .5, 1, and 2 kc/s) of 12 sensorineural impaired Ss (8 bilateral, 4 unilateral) were compared under 3 conditions to determine the influence of the acoustic reflex (AR). The conditions were (1) tones in quiet, (2) tones with contralateral noise 20 db below the AR threshold for noise, and (3) tones with contralateral noise 10 db above AR threshold. The results revealed statistically and clinically significant threshold shifts due to the AR. Clinical implications were discussed.
在三种条件下，对12名感音神经性受损受试者（8名双侧，4名单侧）的离散频率Bekesy听力阈值水平（0.25、0.5、1和2千周/秒）进行比较，以确定听觉反射（AR）的影响。这三种条件分别是：（1）安静环境中的纯音；（2）对侧噪声比AR噪声阈值低20分贝时的纯音；（3）对侧噪声比AR阈值高10分贝时的纯音。结果显示，由于听觉反射，在统计学和临床上均出现了显著的阈值变化。文中讨论了其临床意义。
