The ear drum was made to vibrate using frequency-modulated sound pulses of 40 ms duration, and the vibration velocity of the tip of the mallear handle (umbo) was measured with laser vibrometry before and during stapedius muscle contractions (elicited by sound of 100 dB HL in the contralateral ear). The stapedius reflex caused: an attenuation of the mallear vibrations below 1 kHz, a slight enhancement of the vibrations between 300 Hz and 1,500 Hz. These effects of the stapedius reflex appear to be caused by an increased stiffness in the structures affecting the mallear vibrations.
使用持续时间为40毫秒的调频声脉冲使鼓膜振动，并在镫骨肌收缩之前和期间（由对侧耳100 dB HL的声音引发）用激光振动测量法测量锤骨柄（鼓膜脐）尖端的振动速度。镫骨肌反射导致：1 kHz以下锤骨振动衰减，300 Hz至1500 Hz之间的振动略有增强。镫骨肌反射的这些效应似乎是由影响锤骨振动的结构刚度增加引起的。
