This paper propose a single channel non-stationary noise reduction for teleconferences.The method is composed of the noise detection part and the noise reduction part.The detection part uses a linear prediction residual signal.The reduction part is composed of the two noise reduction methods.The combination of the subband limiter for the noise in high frequencies and harmonic enhancement for the noise in low frequencies
has the effect of noise reducing with fewer distortion caused by reduction processes.The results of computer simulation showed that the A-weighted sound pressure level reduced by about 3.6dB.The results of the subjective tests confirm that the proposed method are effective in improving the tone quality. |
