To study the whole dynamic range of the stapedius reflex the intensity of the soundstimulus with fixed frequency is continuously changed from 70 to 115 dB. Thus we get results concerning the real reflex eleciting intensity level. the gradient caused by continuous intensity change and a possible limit of contraction. To investigate time resolution phenomenons the stimulating signal is pulsated in a second trial. We used this method of stapedius reflex registration with 48 normal ears and a group of patients with sensorineural hearing loss. The results and the diagnostic possibilities of this method are discussed.
为研究镫骨肌反射的整个动态范围,将固定频率的声音刺激强度从70分贝连续变化至115分贝。由此我们得到有关实际反射激发强度水平、连续强度变化引起的梯度以及可能的收缩极限的结果。为研究时间分辨现象,在第二次试验中对刺激信号进行脉动处理。我们将这种镫骨肌反射记录方法应用于48只正常耳和一组感音神经性听力损失患者。讨论了该方法的结果及诊断可能性。
