Various characteristics of tinnitus were surveyed to determine whether they were associated with the acceptance of masking, which is used as a relief procedure for tinnitus. The characteristics considered were duration, loudness match, minimum masking level, and residual inhibition. Data for the characteristics of tinnitus were obtained from the Tinnitus Data Registry at the Oregon Hearing Research Center, which contains information on 784 tinnitus patients. The acceptance of masking was determined by each individual patient based on actual tests with wearable masking units. Variations in the individual characteristics listed above were not found to be significantly associated with the acceptance of masking and thus should not be used a priori to deny patients the opportunity for possible relief of their tinnitus. A masking indicator was found to be significantly (P = .03) associated with the acceptance of masking. This masking indicator is obtained by subtracting the loudness match of the tinnitus from the minimum masking level. When the masking indicator was 10 dB or less, the acceptance of masking was in excess of 50%. The data presented may help to dispel some current misconceptions about the masking of tinnitus.
对耳鸣的各种特征进行了调查，以确定它们是否与掩蔽的接受度相关，掩蔽被用作耳鸣的一种缓解方法。所考虑的特征包括持续时间、响度匹配、最小掩蔽水平和残余抑制。耳鸣特征的数据来自俄勒冈听力研究中心的耳鸣数据登记处，该登记处包含784名耳鸣患者的信息。掩蔽的接受度由每位患者根据使用可穿戴掩蔽装置的实际测试来确定。未发现上述个体特征的变化与掩蔽的接受度有显著关联，因此不应事先以此为由剥夺患者可能缓解耳鸣的机会。发现一个掩蔽指标与掩蔽的接受度显著相关（P = 0.03）。这个掩蔽指标是通过从最小掩蔽水平中减去耳鸣的响度匹配值得到的。当掩蔽指标为10分贝或更低时，掩蔽的接受度超过50%。所呈现的数据可能有助于消除目前关于耳鸣掩蔽的一些误解。
