Abstract:

The starting point in any empirical model such as the Federal Aviation Administration’s (FAA) ; Integrated Noise Model (INM) is a reference data base. In Version 5.2 and in previous versions ; the reference data base consisted solely of a set of noise level data expressed as a function of aircraft power and aircraft-to-receiver distance, i.e., noise-power-distance (NPD) data. To ; accurately account for the inclusion of planned future physical propagation effects in INM, e.g., ground effects and terrain shielding, this noise level data in Version 6.0 was supplemented with frequency-based spectral data.
