摘　　要：耳鸣为非外部刺激产生的主观听觉感知,发病率逐年升高,越来越引起重视。经过调查发现,用某些音乐来缓解耳鸣、调节消极情绪、减压有很好的效果,能打破耳鸣与不良情绪之间的恶性循环链,但重复循环的音乐对耳鸣治疗效果不大。因此,本文提出了一种基于音乐数字设备接口(MIDI)技术和粉红噪声生成耳鸣康复分形声的方法。试听实验结果表明该方法生成的分形片段相似但又不完全重复,没有音调突变,对用康复声进行耳鸣治疗有借鉴意义。Tinnitus is a subjective sensation of sound without external stimulation. It has become ubiquitous and has therefore aroused much attention in recent years. According to the survey, ameliorating tinnitus based on special music and reducing pressure have good effects on the treatment of it. Meantime, vicious cycle chains between tinnitus and bad feelings have been broken. However, tinnitus therapy has been restricted by using looping music. Therefore, a method of generating fractal tones based on musical instrument digital interface （MIDI） technology and pink noise has been proposed in this paper. The experimental results showed that the fraetal fragments were self-similar, incompletely reduplicate, and no sudden changes in pitches and would have a referential significance for tinnitus ther apy.
