A source of error in ipsilateral reflex measurements with impedance methods is explained. It is shown that the inherent non-linearity of the cavity represented by the ear canal and tympanic membrane gives rise to an artifact in the measurement of acoustic impedance which is synchronous with the stimulus. The magnitude of the artifact increases with the intensity of the stimulus, but is relatively insensitive to the frequency of the stimulus. A practical method for measuring the magnitude of the artifact is described.
解释了使用阻抗方法进行同侧反射测量时的一个误差来源。结果表明，由耳道和鼓膜所代表的腔体固有的非线性会在声阻抗测量中产生与刺激同步的伪迹。伪迹的大小随刺激强度增加，但对刺激频率相对不敏感。描述了一种测量伪迹大小的实用方法。
