Ears that collapse from audiometer ear cushion pressure may show elevated stapedial reflex thresholds. In such cases, erroneous judgments about the status of a patient's hearing are possible. Experiments on 15 normal ears suggest that the use of a circumaural ear cushion on the impedance audiometer headset is an effective method of eliminating outer ear closure and the resulting spurious thresholds, when the proper correction values by frequency are applied to the audiometer dial reading. In this study, correction values for reflex-eliciting stimuli are established and their use in a child with collapsing ears is reported.
因听力计耳垫压力而塌陷的耳朵可能会显示镫骨肌反射阈值升高。在这种情况下，对患者听力状况做出错误判断是有可能的。对15只正常耳朵进行的实验表明，当将适当的频率校正值应用于听力计表盘读数时，在阻抗听力计头戴装置上使用环形耳垫是消除外耳封闭及由此产生的虚假阈值的有效方法。在本研究中，确定了引发反射刺激的校正值，并报告了其在一只耳朵塌陷的儿童中的应用情况。
