Method for determinating the ISO-noise levels by simulated aircraft flight operations
Abstract
Models are presented for the evaluation of perceived aircraft noise level as a function of aircraft position and time. The O-point in the engine noise emission coordinates was assumed to be permanently fixed at the aircraft's center of gravity. Changes in the noise characteristics were calculated as a function of the engine energy level, the Doppler effect, and the momentary distance between the aircraft and observer. Results of the adaptation of these models to noise in the vicinity of the Budapest-Ferihegy International Airport are indicated schematically.
