Air traffic
Noise pollution In the air / on the groundEngines
Jet engines – 140 dB Turboprop engines – 130 dB Piston engines – 120 dB
Auxiliary systems Air-conditioning system, heating system,
pressurization, other energy sourcesSupersonic explosion

Air traffic
Noise pollutionFactors influencing noise propagation:
Air relative humidity Air temperature Direction and wind speed Atmospheric turbulence Ground surface (nature and artificial obstacles) Distance from the source

Air traffic
How can we reduce noise?Passive reduction
Influence of terrain Influence of vegetation (trees)
Active reduction Design of sources Engine position Higher angle of climb RWY in use (night restriction) Noise reduction during approach Air route design
