Determination of Aviation Noise Impact Maps from Few Acoustics Measurement Stations

Abstract

A new method is presented that allows the generation of aviation noise maps using a minimum number of measuring stations positioned in strategic points in the vicinity of airports. The data from these measurement stations data, together with the database of aircraft radar tracks, allows for the list of flights (coupled events) that contribute to the estimation of the basic noise parameters. With the described procedure, it is possible to estimate the noise in any point of the space close to the airport and therefore obtain a map of the required parametric quantity, such as Leq day or night, Lden or, as in the case of Italy LVA, a parametric overall daily quantity. The methodology could be used with any other parametric mapping, just by implementing the definition of the specific parameter representative of the local national legislation. For this reason, it could be adopted for any airport provided to have: a measurement at the vicinity of the take-off of each runaway and the track of each flight.
