## Products

- [CadnaA — Noise Prediction & Mapping Software](https://www.datakustik.com/products/cadnaa/): Leading software for the calculation, presentation, assessment and prognosis of environmental noise from industrial, road, railway and aircraft sources. Handles large-scale strategic noise mapping (Lden/Lnight) under EU Directive 2002/49/EC and CNOSSOS-EU, with GIS connectivity and 3D visualisation. Available as Light (smaller projects), Professional (large projects, up to 16 million objects), Basic, and CALC (offloading calculation to physical/virtual machines); licensed per single seat, network server or cloud, by subscription or purchase.
- [CadnaA Features](https://www.datakustik.com/products/cadnaa/features): Calculation (multithreading up to 64 cores, ray tracing, angle-scan, distributed computing PCSP, batch), 3D visualisation, extensive import/export, analysis and post-processing.
