摘　　要：目前临床治疗耳鸣的常用方法是耳鸣掩蔽疗法.国内外传统的耳鸣治疗仪普遍存在耳鸣匹配声源不足以及匹配效果差的缺陷.针对该问题,本文基于雄蝉的生物发声机理,通过分析研究其发声过程,从信号处理的角度提出一种模拟雄蝉发声的模型,用以合成最常见的耳鸣声源——蝉鸣声.实验表明,该模型取得了较好的效果,丰富了蝉鸣声匹配声源,具有一定的医用参考价值.Masking therapy is a commonly-used clinical treatment to cure tinnitus. At home and aboard, the presently-used therapeutic instruments suffer the defect of inadequate matching sound source and poor matching result. To solve such problem, by means of analyzing the sound process of male cicada, a model to synthesize the most frequently-used matching sound - cicada sound is proposed in this paper from the perspective of signal processing. The simulation result indicates that this model successfully synthesize the cicada sound and enrich the matching cicada sound, which makes it a valuable medical reference.
