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 walls. Learn more

  • CadnaR: Calculation of sound indoors. Learn more

Starting from any exterior scenario with sources such as roads, railways or industry, CadnaA calculates the noise levels at the front of the facades of the CadnaB building object. CadnaB building is the link between both programs and can be also a source when the calculation goes from indoors to outdoors.
The noise levels calculated at the facades in CadnaA are automatically synced in CadnaB. Then, CadnaB determines the transmission through the wall based on building acoustic properties including selected constructions, doors or windows.
CadnaR is used to calculate the level at the receiving room considering the real position of sources, receivers and obstacles. The transmission through the wall is calculated based on the building acoustic properties defined in CadnaB.
