his report discusses the phenomenon of out-of-band noise, and examines the results of the out-of-band noise measurements for audio codecs. Frequency spectrum measurements were done on the TLV320AIC33 to analyze the output out-of-band noise. FFTs wer

Fractional Brownian Motion and Sheet as White Noise Functionals，黄志远，李楚进，In this short note, we show that
it is more natural to look the fractional Brownian motion as
functionals of the standard white noises , and the fractional

Noise Generator(白噪音发生器)通过声卡播放,非常有效的噪声发生器，用这个软件煲我的“唯恩”耳机效果非常好，噪音为声音，会产生振动，振动可用于发电，但前提是要够大。噪声对人们的生活应该是非常有害的，但是看你怎么利用，我觉得如果用于警报或是需要让人们重视的场合，是非常有效的，这是一个非常有效的噪声发生器,通过声卡播放。白噪音指的是在20Hz~100kHz频率范围内具有均匀的谱密度。噪声信号的幅度分布为高斯公布，在20Hz~20kHz范围内的不均匀度约为±1Db。

We consider an epidemic disease system by an additive fractional white noise to show that epidemic diseases may be more competently modeled in the fractional-stochastic settings than the ones model.
This paper describes a method for enhancing
speech corrupted by broadband noise. The method is
based on the spectral noise subtraction method.
The original method entails subtracting an estimate
of the noise power spectrum from the speech power
