Supported noise models
Road Noise | sonROAD18
D-noise with sonROAD18 for calculating road traffic noise in accordance with Annex 3, NAO, taking into account engine and rolling noise as well as sound emission characteristics depending on vehicle classes. In addition to the SWISS10+ vehicle categories, tram noise on roads can also be calculated.
Railway Noise | sonRAIL
D-noise with sonRAIL for calculating railway noise in accordance with Annex 4, NAO. In addition to annual exposure levels, the impact of noise protection measures at the source and along the propagation path can be simulated.
Aircraft Noise | sonAIR
The sonAIR solution as an add-in for ArcGIS Pro for calculating aircraft noise in accordance with Annex 5, NAO. In addition to annual exposure, forecasts, and scenarios, sonAIR can also be used to simulate individual flights and optimize low-noise approach and departure procedures.
Shooting Noise | sonARMS
sonARMS has been integrated into D-noise, providing a user-friendly GUI for shooting noise calculations in accordance with Annexes 7 and 9 of the NAO.
