It has been suggested that hearing level might be assessed by comparing the acoustic reflex thresholds (ARTs) for two modes of stimulation: by pure tones alone and by a combination of two pure tones, one of which is used as a "preactivator." Using an extrapolatory method for determining the reflex thresholds, 35 subjects (17 normal hearing and 18 hearing impaired) were used to test the above hypothesis. For the individual frequencies 75% of the hearing levels estimated from the ARTs lay within +/- 10 dB of the true threshold, and 97% within +/- 20 dB. However, although the method does appear to be more accurate than the Niemeyer and Sesterhenn method of estimating hearing loss from the ARTs for pure tones and noise bands, it has limitations due to the high levels of preactivating tone required, and the number of stimuli it is necessary to use. Some possible refinements are suggested that might improve the clinical applicability of the technique.
有人提出，可以通过比较两种刺激模式下的听觉反射阈值（ARTs）来评估听力水平：仅通过纯音以及通过两种纯音的组合，其中一种用作“预激活音”。使用一种外推法来确定反射阈值，35名受试者（17名听力正常和18名听力受损）被用于测试上述假设。对于各个频率，从ARTs估计的听力水平中有75%落在真实阈值的±10 dB范围内，97%落在±20 dB范围内。然而，尽管该方法似乎比Niemeyer和Sesterhenn从纯音和噪声带的ARTs估计听力损失的方法更准确，但由于所需的预激活音水平较高以及必须使用的刺激次数，它存在局限性。有人提出了一些可能的改进措施，这些措施可能会提高该技术的临床适用性。
