This paper describes a practical estimation method of the probability distribution form for the environmental noise by using the roughly observed data with quantized levels. First, a general expression of the probability density function (abbr., pdf) is introduced for the original noise level fluctuation of continuous level type before passing through the level-quantization mechanism, Next, a new estimation method of the distribution parameters in the above general expression is proposed by using the statistical information on the roughly observed data with quantized levels. On the basis of this estimation theory, Lx and Leq noise evaluation indices can practically evaluated. The effectiveness of the proposed method is also exprimentally confirmed by applying it to the actual road traffic noise data.
