In this paper, we proposed a method of signal extraction from noisy signal using physical constraints related to the four regularities proposed by Bregman, and by solving the problem of segregation two acoustic sources. We carried out two simulations on segregating two-acoustic sources using noise-added signal f(t) to show that the proposed method can extract the desired signal f1(t) from it. Simulation 1, showed that the proposed method can extract an AM complex tone from a noise-added AM complex tone in which signal and noise exist in the same frequency region, with high precision. In particular, using the proposed method, it is possible to reduce the SD by about 20 dB. Moreover, simulation 2 showed that the proposed method can also extract a speech signal from noisy speech.
