摘要：

In order to evaluate noise in a sound environment, it is necessary to estimate the sound levels at evaluation points based on the observations at a reference point. In this study, a method is derived based on the observations contaminated by a background noise to estimate system parameters reflecting several orders of correlation information between the evaluation and reference points in a complex sound environment. Furthermore, a statistical evaluation method for traffic noise under the existence of background noise is proposed. The effectiveness of the proposed method is experimentally confirmed by applying it to the traffic noise data measured in a complex sound environment. © 2015, International Institute of Acoustics and Vibrations.
