CadnaA 4.3

CadnaA by DataKustik is professional software for environmental noise prediction and mapping. Designed for acoustical consultants, planners, and authorities, it models outdoor sound propagation from sources such as road and rail traffic, industrial facilities, and wind turbines in 2D and 3D. Users can build detailed digital environments—including terrain, buildings, barriers, and ground types—import GIS/CAD data, place sources and receivers, and compute standard noise indicators such as LAeq, Lden, and Lnight. CadnaA supports widely used international and national calculation methods, including ISO 9613-2 and CNOSSOS-EU, helping ensure compliance with local regulations.

The software produces clear deliverables such as contour maps, façade level evaluations, grids, and receptor-point tables, and it streamlines reporting with scenario comparisons and high-resolution graphics that can be exported to common GIS and CAD formats. Optional modules extend functionality for specific source types and large-area studies. Known for its efficiency and reliability, CadnaA (Computer Aided Noise Abatement) is used worldwide to support permitting, environmental impact assessments, and noise action plans—enabling data-driven decisions for quieter, better-planned communities.
