• The noise evaluation index, L_<eq>, plays an important role in the field of noise evaluation and/or regulation problems. At this time, the sound level fluctuation is often measured within a restricted range due to a dynamic range of measurement instruments. This incomplete measurement occurs the lack of measurement accuracy of L_<eq>. In this paper, a restoration method of statistical information on the sound level fluctuation is first proposed by using the above incomplete sound level data under the assumption of a standard Gaussian distribution. Next, a practical estimation method L_<eq> is proposed by using the estimated statistical information on the mean value and the variance of the sound level fluctuation. The validity of the proposed estimation method is first confirmed through some simulation experiments. The practical effectiveness of the proposed method is experimentally confirmed by applying it to the actual road traffic noise data.
