What are the benefits of a Noise and Flight
Track Monitoring system for an airport?
 Overview of noise impact on residents near
the airport
 Visualization of flight tracks and the
quality of track keeping
 Able to watch long term trends in airport
noise
 Better answers to complaints
Check of noise contours

How do the Airports in Europe Noise
Monitoring ?
With several noise monitoring terminals
Central database
Interfaces to flight plan and radar data

What are the results of the acoustical
measurement?
Number of noise events
 Lmax= maximum noise of each aircraft
and average Lmax values for each aircraft
Average value of noise (Energetic sum) at the
station : Leq, Lday, Lnight, LDEN per day, per
week, per weekend, per month, per year
Aircraft Noise and Flight Track
Monitoring System
What is the LDEN according EU Directive
2002/49?
Energetic Sum of all aircraft noise events
Noise events during evening + 5 dB
 Noise events during night
