Abstract

The issue of aircraft noise experienced by residents in the airport’s vicinity is one of subjective annoyance. Any efforts at noise abatement have been presented to residents in terms of noise level reductions in conventional metrics such as A-weighted level (dBA) or equivalent sound level Leq. This conventional approach proves insufficient in increasing aircraft noise acceptance due to two main reasons – firstly, the residents have only a rudimentary understanding of changes in decibel (dB) and secondly, the conventional metrics do not fully capture what the residents actually find annoying i.e. characteristics of aircraft noise they find least acceptable. In order to allow least resistance to air-traffic expansion, the acceptance of aircraft noise has to be increased, for which a new approach to noise assessment is required. To this end, a novel aircraft noise simulation technique has been developed at RWTH Aachen University, which makes use of aircraft noise auralization and 3D visualization to make it both heard and seen in immersive Virtual Reality (VR) environments. This technique is intended to be used to increase the residents’ acceptance of aircraft noise by presenting noise changes in a more directly relatable form, and also aid in understanding what contributes to the resident’s subjective annoyance via psychoacoustic surveys. This paper describes this technique and some of its initial applications.
