| 内容記述 | The noise evaluation index, L_<eq>, plays an important role in the field of noise evaluation and regulation problems. For the measurement of L_<eq>, it is very convenient to utilize the statistical information on the noise level fluctuation. The well-known evaluation method using the above statistical information was derived under the assumption of a standard Gaussian distribution with the infinite fluctuation range. In an actual noise level fluctuation, however, the fluctuation range is necessarily restricted to some finite value. In this paper, a practical method for evaluating L_<eq> using lower order statistics is proposed by considering matching to above restricted fluctuation range. More specifically, an evaluation method of Leq is derived by the introduction of the Beta distribution matched to the fundamental information on the existence of this finite fluctuation. The effectiveness of the proposed evaluation method is experimentally confirmed by applying it to actual road traffic noise data. Namely, it is shown that the results estimated using the proposed method are in good agreement with the experimental results, compared with the agreement obtained with the results estimated using the usual method derived under the assumption of a standard Gaussian distribution. | |||||
