Connectivity

CadnaB offers several import options, such as BASTIAN format. In addition, CadnaB can be connected to CadnaA and CadnaR covering a wide range of applications.


Import of BASTIAN worksheets

CadnaB provides an easy to use import of BASTIAN worksheets. The single room pair can be directly used for calculation according to EN 12354 – Series 2017. If the user activates the compatibility mode to the former series 2000, comparable results to BASTIAN can be generated.

All information required for the calculation is transferred during the import:

  • Constructions
  • Configuration of calculations
  • Interior sources

Interoperability with CadnaA

CadnaB-buildings can be placed in a CadnaA model with a few clicks to calculate the level in front of the façade. In consideration of the building acoustic properties defined in CadnaB, the interior level can be calculated according to EN ISO 12354.

Interoperability with CadnaR

  • Manage and organize CadnaR files for an entire building in CadnaB.
  • Use CadnaR in the sending and receiving room to consider the position of sources, receivers and obstacles inside the room. The transmission through the wall is calculated based on the building acoustic properties defined in CadnaB including selected constructions, doors or windows.
  • Automatic calculation of the spatially averaged reverberation time for all rooms which are linked to a CadnaR project.

Interoperability with CadnaA and CadnaR

Connect both CadnaA and CadnaR with CadnaB for an extended transmission calculation from outside to inside and vice versa:

Outside to inside: (see video)

  • Starting from an exterior source (e.g. a road), CadnaA calculates the level in front of the façade.
  • CadnaB then determines the transmission through the wall based on building acoustic properties including selected constructions, doors or windows.
  • CadnaR is used to calculate the level inside the room at a specific workplace considering existing sources and obstacles. 

Inside to outside:

  • Starting from interior sources (e.g. machinery), CadnaR calculates the levels in front of the walls inside the room considering existing obstacles.
  • CadnaB then determines the transmission through the wall based on building acoustic properties including selected constructions, doors or windows.
  • CadnaA is used to calculate the propagation to the outside of the radiating building.
