We have demonstrated the elevated reflex thresholds and decreased bandwidth effect in listeners with sensorineural hearing loss, and we have extended this generalization to include those with hearing loss related to presbycusis. A bivariate plotting method has been described for predicting hearing loss from reflex threshold data that is characterized by a low rate of false positives, while successfully identifying those with a moderate degree of hearing loss (greater than 32 dB) more than 80% of the time. We found no evidence of decreasing reflex threshold with age. Instead, our reflex thresholds for normal hearing subjects tend to remain the same or increase slightly as age increases. It is hoped that these findings will stimulate further work to correlate reflex thresholds with hearing levels. This information should be used to test infants (especially those at high risk for hearing loss) and other subjects unable to respond to conventional audiometric testing.
我们已经证明，感音神经性听力损失的听众存在反射阈值升高和带宽效应降低的情况，并且我们已经将这一普遍现象扩展到包括与老年性听力损失相关的听力损失患者。已经描述了一种双变量绘图方法，用于根据反射阈值数据预测听力损失，该方法的特点是假阳性率低，同时在超过80%的时间里能成功识别出中度听力损失（大于32分贝）的患者。我们没有发现反射阈值随年龄下降的证据。相反，我们发现正常听力受试者的反射阈值往往会随着年龄的增长保持不变或略有增加。希望这些发现将激发进一步的研究工作，以将反射阈值与听力水平相关联。这些信息应用于测试婴儿（尤其是那些有听力损失高风险的婴儿）以及其他无法对传统听力测试做出反应的受试者。
