A study on the estimation of LAeq in residential areas.

In this paper, two methods of estimating the average level of environmental noise (LAeq) in residential area with small traffic density are proposed. The first one provides a general way of estimating LAeq for noise whose level is arbitrarily distributed. In the second one, LAeq is estimated on the basis of a mathematical model that the traffic flow forms the Poisson distribution. The LAeq values estimated using these methods are found satisfactorily consistent with the actual field data.
