A model for the rapid assessment of the impact of aviation noise near airports

Abstract

This paper introduces a simplified model [Rapid Aviation Noise Evaluator (RANE)] for the calculation
of aviation noise within the context of multi-disciplinary strategic environmental assessment
where input data are both limited and constrained by compatibility requirements against other disciplines.
RANE relies upon the concept of noise cylinders around defined flight-tracks with the Noise
Radius determined from publicly available Noise-Power-Distance curves rather than the computationally
intensive multiple point-to-point grid calculation with subsequent ISO-contour interpolation
methods adopted in the FAA’s Integrated Noise Model (INM) and similar models. Preliminary
results indicate that for simple single runway scenarios, changes in airport noise contour areas can
be estimated with minimal uncertainty compared against grid-point calculation methods such as
INM. In situations where such outputs are all that is required for preliminary strategic environmental
assessment, there are considerable benefits in reduced input data and computation requirements.
Further development of the noise-cylinder-based model (such as the incorporation of lateral attenuation,
engine-installation-effects or horizontal track dispersion via the assumption of more complex
noise surfaces formed around the flight-track) will allow for more complex assessment to be carried
out. RANE is intended to be incorporated into technology evaluators for the noise impact assessment
of novel aircraft concepts.
