Two experiments were conducted on normal hearing adults to assess the audiometric test potential of reflex modulation (RM) when administered according to the descending method of limits. RM describes the inhibitory effect of a tone upon a subsequently occurring eyeblink reflex. Although RM conducted according to the method of constant stimuli has already been shown to produce RM results which agree well with voluntary audiometry in normal and hearing-impaired adults and children, the present concern is with the potential clinical application of RM, and in this regard the descending method may offer certain distinct advantages. In study one, a 2-kHz tone was presented at several descending intensities, whereas in study two, four different frequencies (0.5, 1.2, and 4 kHz) were presented in concurrent fashion, but again, the intensity of the complete set was decreased in successive steps. Sensitivity in both cases was 10 to 15 dB SL. Implications for the clinical application of RM audiometry are discussed.
对听力正常的成年人进行了两项实验，以评估按极限递减法进行反射调制（RM）时的听力测试潜力。RM描述了一个纯音对随后出现的眨眼反射的抑制作用。尽管已经证明按恒定刺激法进行的RM所产生的结果与正常及听力受损的成年人和儿童的主观听力测试结果吻合良好，但目前关注的是RM的潜在临床应用，在这方面递减法可能具有某些明显优势。在研究一中，以几种递减强度呈现2千赫兹的纯音，而在研究二中，以同时的方式呈现四个不同频率（0.5、1.2和4千赫兹），但同样，整套频率的强度以连续步骤降低。两种情况下的敏感度均为10至15分贝听力级。讨论了RM听力测试临床应用的意义。
