Noise contours

Fraport regularly reports to the Hessian Ministry of Economics, Energy, Transport and Housing (HMWEVW) on changes in aircraft noise in the vicinity of the airport. As well as measuring aircraft noise, Fraport also calculates aircraft noise levels. Unlike mere measurements, which provide information only on the aircraft noise footprint in the direct vicinity of the measurement station, these calculations depict aircraft noise levels over the entire area in the period assessed.  

Take a look at day and night aircraft noise contours on our interactive FRA.Map.

Calculation basis  

Aircraft noise calculations are based on the Instructions on the Calculation of Noise-Protection Areas (Anleitung zur Berechnung von Lärmschutzbereichen, AzB) and the Instructions on the Acquisition of Data on Flight Operations (Anleitung zur Datenerfassung über den Flugbetrieb, AzD), which were introduced in Germany and last updated in 2008. They relate to the busiest six-month period of the year in question – at Frankfurt Airport this is generally between May and October.

The aircraft-specific noise data in the Instructions on the Calculation of Noise-Protection Areas (Anleitung zur Berechnung von Lärmschutzbereichen) from 2008 (AzB-08) were collected several years before the AzB-08 was published. In this aircraft noise calculation, newer aircraft types that have been commissioned since this time are treated the same acoustically as the older types with comparable capacity. 

However, as some of the new types have far lower noise emission levels than their predecessors (Airbus A380, Boeing B787, A320neo, A350 and others), Fraport has carried out additional aircraft noise calculations since 2017 in which the movements of modern aircraft types are allocated to modified aircraft groups in line with noise emission data. 

The method used for the calculation with noise reduction measures is the same as the method used in monitoring calculations for the noise emission ceiling. For details on this, see the monitoring report on the noise emission ceiling in 2017.
