有三种装置可以用来缓解耳鸣,即助听器、耳鸣掩蔽器及耳鸣器(tinnitus instrument)。耳鸣器既具有放大的功能,又发出噪声,可用于既有听力减退又有耳鸣的病人。这些装置缓解耳鸣的机制可能是由于耳鸣病人对外界的噪声比对本身的耳鸣较易耐受和掩蔽噪声的后效抑制作用。作者们报告了598例耳鸣病人用这种掩蔽装置的结果。从1976至1978年的493人为第一组,1979年的105人为第二组。在第一组中,因为(1)试用未能达到对耳鸣起有效的掩蔽,(2)病人感到掩蔽噪声难以
There are three devices that can be used to relieve tinnitus, namely hearing aids, tinnitus maskers and tinnitus instruments.

In the first group, because (1) the trial failed to achieve effective masking of the tinnitus, (2) the patient felt masking noise was difficult
