This paper describes a practical estimation method of the input-output statistical relationship for the sound environmental system, especially in an actual situation when observation values of the input and output response are roughly observed due to the level quantization mechanism of measuring equipment. First, a general expression of the joint probability density function (abbr., pdf) is introduced for the original input-output fluctuations of continuous level type before passing through the level-quantization mechanism. Next, an estimation methods of the distribution parameters in the above general expression is proposed by using the statistical information on the roughly observed input and output data with quantized levels. By using the estimated result, the output probability distribution for another kind of input is predicted along the same line of so-called extended regression analysis.
