Estimation of directivity and sound power levels emitted by aircraft during taxiing, for outdoor noise prediction purpose

Integrated noise model (INM) is the most internationally used software to calculate noise levels near airports. Take off, landing or pass by operations can be modeled by INM, but it does not consider aircraft taxiing, which, in some cases, can be important to accurately evaluate and reduce airports’ noise assessment. Aircraft taxiing noise emission can be predicted using other prediction tools based on standards that describe sound attenuation during propagation outdoors. But these tools require data inputs that are not known: directivity and sound power levels emitted by aircraft during taxiing .This paper describes methods used to calculate directivity indexes and sound power levels, based on field measurements made in Madrid-Barajas Airport (Spain). Obtained results can be used as inputs for general purpose outdoor sound prediction software, which will be able to evaluate noise at airports vicinity as industrial noise. Directivity and sound power levels have been estimated in octave and third octave band terms, for several aircraft families. (A) “Reprinted with permission from Elsevier”.
