Every information on the statistical property of state variables for the actual system of environmental noise with various types of probability form, nonstationarity, nonlinearity and arbitrary correlation property can be derived by first finding the expression of the multivariate joint probability function of the state variables. In this paper, the generalized expression of joint probability function in the form of statistical orthogonal expansion series with the quantized or continuous levels can be derived in a suitable form to the actual situation on the variety of probability fluctuation and digital or analogue type level observations, especially by focussing our aim on the basic viewpoint. Finally, after once the legitimacy of the present theory is confirmed by means of digital simulation, the effectiveness of the generalized method is confirmed by applying it to experimentally observed road traffic noise data.
