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.
