| Abstract | Airport noise planning models typically use guidance contained in the Society of Automotive Engineers (SAE), Airspace Information Report (AIR), SAE-1845, titled “Procedure for the Calculation of Airplane Noise in the Vicinity of Airports [1]. This document shares material similar to that in European Civil Aviation Conference (ECAC) Doc 29 [2] and International Civil Aviation Organization (ICAO) Circular 205 [3]. All three documents define a noise source and propagation that compute noise exposure for a reference terrain of acoustically absorptive, soft ground and a single reference atmosphere considered to be representative of average worldwide airport conditions. Detailed source data are used to propagate noise relative to this reference atmosphere through the use of noise-power-distance (NPD) databases. One-third octave-band data are not inherently required in noise models of this type. Proposed updates to the above guidance documents allow for the modeling of airport-specific atmospheric conditions and terrain. Adjusting for these local conditions requires the addition of spectral data to community airport noise models. This paper proposes to develop these spectral data as a natural extension to the guidance already specified in References 1-3. The authors describe the derivation of spectral class data for the Federal Aviation Administration’s (FAA) Integrated Noise Model (INM), several validation and verification procedures used for spectral class data, and recommend updated language to the guidance given in References 1-3 to account for one-third octave- band data. |
