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 the subjective auditory perception caused by non-external stimuli, and the incidence has been increasing year by year, attracting more and more attention. After the survey found that some music to ease the tinnitus, regulate negative emotions, decompression has a good effect, can break the vicious circle between tinnitus and bad mood chain, but the music is not repeated on tinnitus treatment effect. Therefore, this paper presents a method of generating fractal sound of tinnitus recovery based on the MIDI technology and pink noise. Experimental results show that the method of fractal fragments generated by similar but not completely repeated, no pitch mutation, the use of rehabilitation for tinnitus therapy has reference.
