Traditional tinnitus maskers are generators that deliver a grossly inaccurate broad band high energy noise which most tinnitus patients find an excessive noise intrusion, unacceptable and intolerable. Audiometric analysis defines tinnitus in terms of frequency and intensity. The 321Q-minimum energy narrow band microtek maskers (Mikrotek, Medical, Inc. Columbus) deliver a variable width and a low energy noise that is programmable to any frequency within the audible spectrum. We studied one hundred consecutive tinnitus patients. All patients underwent thorough ENT-analysis and audiometry. Only eight of them could be provided with the masking device and only four found some relief with its use. No correlation in the parameters could be found to discriminate between satisfied and unsatisfied patients.
传统耳鸣掩蔽器是一种产生严重不准确的宽带高能噪声的发生器，大多数耳鸣患者认为这种噪声干扰过大，无法接受且难以忍受。听力测定分析根据频率和强度来定义耳鸣。321Q型最小能量窄带微型掩蔽器（米克罗泰克，医疗公司，哥伦布）发出可变宽度和低能量的噪声，该噪声可在可听范围内编程到任何频率。我们研究了100例连续的耳鸣患者。所有患者均接受了全面的耳鼻喉科分析和听力测定。其中只有8人能够使用掩蔽装置，只有4人使用后有所缓解。在满意和不满意的患者之间，未发现参数上的相关性以进行区分。
