远缘(间接)掩蔽(remote masking)是指暴露于80～100dB SPL高频带噪声时低频听闻提高的现象。这曾被认为是由于非均匀信号引起耳蜗分隔机械性非线性扭曲所致,并将其作为检查耳蜗分隔劲度的一种方法。作者们对139例感音性聋患者作了有关远缘掩蔽的临床研究。正常青年人远缘掩蔽幅度分为:250Hz 21～34dB,500Hz12～29dB,1000Hz18～32dB。低于以上的下限者,即为远缘掩蔽病理值。美尼尔病患者及老年性聋者的远缘掩蔽值
Remote masking refers to the phenomenon of increasing low frequencies when exposed to 80-100 dB SPL high-band noise. This was previously thought to be due to mechanical non-linear distortions of the cochlear septum caused by non-uniform signals and as a means of examining the stiffness of the cochlea. The authors conducted a clinical study of distant masking on 139 cases of sensorineural deafness. The range of masking distance of normal young people is divided into: 250Hz 21 ~ 34dB, 500Hz12 ~ 29dB, 1000Hz18 ~ 32dB. Below the lower limit of the above, that is, the value of distant masking pathology. Menarche disease and senile deafness of the remote masking value
