A method of prediction of the output probability distribution of noise level or L_α is studied in the case when the random sound pressure wave with non-Gaussian distribution type having the linear and non-linear correlation among many sampled time points is passed especially through the N-fold walls of the linear sound insulation systems. The impulse response in a time domain is derived for the N-fold walls from their transfer function in a frequency domain, and the input and output relation is described with this impulse response. The probability density function of transmitted energy through the N-fold walls is discussed by using this input and output relation. The validity of the theoretical results, is verified by the experiment where an aluminium triple walls is set between two reverberation rooms and the sound pressure wave recorded in the actual traffic noise is used as a sound source.
