According to simple computation, good anti-noise ability and low precision of Katz algorithm and complex computation and good precision of box-counting dimension and correlation dimension, an Improvement fractal algorithm Based on Wave is presented and analyzed through the fractal Brown curve and noisy speech according to the characteristic of the box dimension and Katz dimension.

摘要该文针对目前的分维计算方法——盒维、关联维等精度虽高，但计算复杂，Katz维计算简单、抗噪性能好、但精度不高的现状，提出了一种改进的基于波形的算法——IBW-FD，分析了对分形布朗曲线、含噪语音(高斯白噪声，三种非平稳噪声)的性能。

Methods 22 parients(35 ears)had been tested in three noises, including white noise,speech noiseand babble noise.BN was recorded when 8～12 persons were talking at same time.The monosyllabic phonetic balance word list was made by Shen Ye in 1983 and every list includs twenty-five words,Meantime ,the effect to speech discrimination score curve was tested in different signal to noise ratio.

目的 为了观察传导性聋患者在噪声竞争下言语清晰度曲线及不同噪声对清晰度曲线的不同影响；方法测试22名(35耳)传导性聋患者三种不同噪声竞争下测得的言语识别率结果，这三种噪声为①白噪声(white noise，WN)，②言语噪声(speech noise，SN)，③多人谈话声(babble noise，BN)，即由8～12人同时讲话录制而成，其频谱与言语长时平均频谱接近。

frequency curve：频率曲线

厂商一般以图形方式标示出录音设备记录不同频率声音的特性,我们称之为频率曲线(frequency curve). 有些传声器具有语音衰减(speech bump)设计,就是特意要追求一种更适用于人声频率范围的拾音效果. 音量和振幅 除了频率之外,
