德国研究人员2009年12月28日在美国《国家科学院院刊》(PNAS)上公布报告称,个性化设计的音乐疗法有助于改善耳鸣症状。
德国曼斯特大学的研究人员根据8名耳鸣患者的音乐喜好分别设计了个性化音乐疗法,并移除了患者耳鸣频率的匹配音频。接受这种修改版音乐疗法治疗一年后,受试者报告说,他们的耳鸣症状明显得到改善。
耳鸣是指在没有任何外界刺激条件下产生的异常声音感觉。科学界目前尚未查明耳鸣的成因,不过耳鸣患者处理听觉信息的大脑区域――听觉皮层通常都有所损伤。
研究人员表示,他们开发的疗法成本低、令人愉悦,可以显著改善耳鸣患者的症状。

Maladaptive auditory cortex reorganization may contribute to the generation and maintenance of tinnitus. Because cortical organization can be modified by behavioral training, we attempted to reduce tinnitus loudness by exposing chronic tinnitus patients to self-chosen, enjoyable music, which was modified (“notched”) to contain no energy in the frequency range surrounding the individual tinnitus frequency. After 12 months of regular listening, the target patient group (n = 8) showed significantly reduced subjective tinnitus loudness and concomitantly exhibited reduced evoked activity in auditory cortex areas corresponding to the tinnitus frequency compared to patients who had received an analogous placebo notched music treatment (n = 8). These findings indicate that tinnitus loudness can be significantly diminished by an enjoyable, low-cost, custom-tailored notched music treatment, potentially via reversing maladaptive auditory cortex reorganization.
