In this paper, a new attempt at the estimation for the noise level probability distribution is proposed based on the known values of several specific Lx noise evaluation indices. Here, the effect of the restricted amplitude fluctuation range matched to the actual stochastic phenomenon on the estimation accuracy is reasonably taken into consideration. The effectiveness of the proposed method is experimentally confirmed by applying it to the
actually measured road traffic noise data.
