The aim of this study was to investigate the effects of tinnitus on mental activity. In a mixed design study, the performance of 20 subjects with tinnitus and 20 healthy control subjects was compared on the digit-symbol test, completed in three auditory conditions: silence, masking and intermittent masking. Results showed marked overall differences between patients and controls on all three conditions. Lower scores on the digit-symbol test were observed during the intermittent masking condition compared with the masking condition for the patients. There was no difference between silence (e.g. tinnitus) and the masking condition, or between silence and the intermittent masking condition. The control subjects scored lower on the task when exposed to the intermittent masking compared to both silence and masking. The patients had higher depression and anxiety scores than the controls. These findings suggest that there is a link between masking sounds and how tinnitus affects cognitive capacity.
本研究的目的是调查耳鸣对心理活动的影响。在一项混合设计研究中，对20名耳鸣患者和20名健康对照者在数字符号测试中的表现进行了比较，该测试在三种听觉条件下完成：安静、掩蔽和间歇性掩蔽。结果显示，在所有三种条件下，患者和对照者之间存在明显的总体差异。与掩蔽条件相比，患者在间歇性掩蔽条件下数字符号测试的得分更低。安静（如耳鸣）与掩蔽条件之间，或安静与间歇性掩蔽条件之间没有差异。与安静和掩蔽条件相比，对照者在暴露于间歇性掩蔽时任务得分更低。患者的抑郁和焦虑得分高于对照者。这些发现表明，掩蔽声音与耳鸣如何影响认知能力之间存在联系。
