The present invention relates to improving sound quality. Provided is a method and an apparatus for estimating adaptive noise in a multiple-microphone-based sound quality enhancement system. According to the present invention, the method can react adaptively to provide constant tone even when the type of noise is changed and have less loss of voice in an unusual noise environment of a low signal to noise ratio (SNR). Additionally, the method is able to react against impulse noise in real time and to process the noise in real time even if the type of the noise is suddenly changed. Further, the present invention is able to increase versatility and requires tuning in a short time by using low power consumption according to a small operation amount, and provides solutions as a software type library. |
