CadnaA now calculates padel and pickleball courts — DataKustik has derived the missing emission values and integrated them into the model.
CadnaR 2026 introduces powerful data filtering, global language compatibility as well as improvements to import formats.
CadnaA 2026 MR1 now with calculation of padel courts and export of GeoPackage (.gpkg).
CadnaB 2025 – now with Cloud Licensing! Take advantage of the new “use actual dimensions” feature to factor in wall thicknesses and linings directly when determining the geometry!
Software for Immission Protection
We are the leading software companies in the field of acoustics. Our focus is the ongoing development of our software systems for the calculation of noise outdoors (CadnaA), for the assessment of sound distribution indoors (CadnaR) and for the calculation of sound transmission between rooms (CadnaB). Our Software is used by governmental agencies, airports, road and railway authorities, international industrial enterprises as well as by leading consulting companies around the world.
One platform, three tools, effortless integration!
By combining CadnaA,CadnaR, and CadnaB, you utilize the capabilities of a fully integrated sound calculation. This includes outdoor sound propagation up to the building façade, transmission through the wall construction into a room, and further propagation through various rooms. The CadnaA/B/R software system is currently the only system capable of performing this task within a single software platform.
CadnaA: calculation of noise outdoors.
CadnaB: sound transmission through façade elements.
CadnaR: Calculation of sound indoors.
We develop software for environmental protection
We are proud to be considered as one of the leading developers of software for immission protection. Our products for the calculation and prediction of environmental noise, interior sound and air pollutant distribution as well as for building acoustics are state-of-the-art. The main objective of our work is the implementation of the noise propagation theory into easy-to-use software. Therefore, one of the most valued advantages of our programs is their high usability and flexibility, while the existence of sophisticated tools and options allow to handle any complex project. These are key points to the successful application of our software worldwide.
Another key aspect of our work is our ongoing research and consulting at both national and international levels. We develop and refine noise calculation methods and standards by participating in international working groups, and we adapt our calculation procedures for use in different software environments.
Not least, DataKustik is committed to democratizing noise mapping and interior sound software. One of our most important activities here is the continuous training and education of professionals – from users of our software to consultancy firms and acoustics departments in public administration, across every field of acoustics. Beyond that, we collaborate with leading universities worldwide to train the acoustics experts of tomorrow.
