Zusammenfassung:	In a method for removing noise according to an embodiment of the present invention, a first estimated output signal calculated on the basis of a first previous far-end channel filter, a second previous far-end channel filter, and an input signal corresponding to a previous frame can be provided. A first current far-end channel filter corresponding to a current frame may be updated according to thefirst estimated output signal and the first previous far-end channel filter. A second estimated output signal calculated on the basis of the first current far-end channel filter, the second previousfar-end channel filter, and the input signal may be provided. A second current far-end channel filter corresponding to the current frame may be updated according to the second estimated output signaland the second previous far-end channel filter. A result signal calculated on the basis of the first current far-end channel filter, the second current far-end channel filter, and the input signal maybe provided. By using the m
