Abstract

This paper considers the environmental acoustics metrics conversion problem in relation to airport noise. In many countries, there is a need to change the metrics used in airport noise studies and to establish the relation between two different metrics, like day night sound level DNL, used in airport noise zoning and LAeq used in urban areas. Here we present a practical method for airport noise metrics conversion. We present the theoretical basis for a practical way to compare DNL and LAeq as well as case study examples.
