这些实验的目的是确定中耳反射的发生率，在几个非声（触觉和空气喷射）刺激的正常听力的受试者谁有一个声音反射和选定的严重听力损失的患者。结果表明，对触觉刺激的反应的发生率增加的面部区域刺激接近耳廓。对指向眼睛的空气喷射刺激的反应很高;然而，空气喷射的临床效用可能受到限制，因为它经常导致惊吓反应和头部运动，并且反应容易出现疲劳。在正常的听者中，对耳部空气喷射刺激的反应可能是声刺激和触觉刺激的结果。触觉刺激反射的存在，以及正常的鼓室导抗构成了中耳正常的有力证据，但缺乏对听觉或触觉刺激的反射仍然导致潜在镫骨肌功能的模糊确定。
The purpose of these experiments was to determine the incidence of the middle ear reflex in response to several nonacoustic (tactile and air jet) stimuli among subjects with normal hearing who had an acoustic reflex and selected patients with severe hearing loss. The results demonstrate that the incidence of response to tactile stimulation increases as the facial area stimulated approaches the auricle. The response to an air jet stimulus directed toward the eye is high; however, the clinical utility of the air jet may be limited because it often results in a startle reaction and head movement, and the response appears to fatigue easily. In normal listeners the response to auricular air jet stimulation probably results from both acoustic and tactile stimulation. The presence of a reflex to tactile stimulation, together with normal tympanometry constitutes strong evidence of a normal middle ear; but the absence of a reflex to acoustic or tactile stimuli still leads to an ambiguous determination of potential stapedial muscle function.
