D-noise

D-noise is a GIS based solution for the calculation, analysis and visualization of noise and the planning of noise remediation measures.

D-noise is based on Esri ArcGIS for Desktop and is available as Add-In for ArcMap and ArcGIS Pro.

In addition to calculations with the new Swiss noise calculation models sonAIR, sonRAIL, sonROAD18 and sonARMS for flight, street, railway and shooting noise calculations, D-noise implements the older Swiss models StL86+, sonROAD and Semibel. It also offers interfaces for noise calculations with CadnaA and over a QSI-interface with a large number of third party solutions.

The noise simulation models of the son-series are based on the latest research results of Empa on the generation and propagation of noise and therefore allow an exceptionally realistic image of high quality of a wide variety of noise situations.
