The method of noise analysis of aircleaners with random transfer function is presented using matrix perturbation theory, matrix calculus, Kronecker algebra and generalized second moment method. Considering the uncertainty factors of the atmosphere, the random response of the aircleaner is described clearly in the time and space domain, and the decibel (A) value of the former second moment of random response at the sound outlet of the aircleaner is obtained.
