PRE-RELEASE INFORMATION

CadnaB is the software to calculate airborne and impact sound transmission between rooms for an entire building including airborne sound transmission from and to the exterior. The calculations in CadnaB are based on parts 1 to 3 of the European Standard series EN 12354, being adopted by most of the European countries as part of their national standards.

CadnaB – Calculation of sound transmission between rooms for an entire building

  • Apply CadnaB to calculate airborne and impact sound transmission between rooms for an entire building including airborne sound transmission from and to the exterior.

  • Calculation according to the European Standard EN 12354-2017, Parts 1, 2 and 3. Further calculation procedures and national standards will be implemented in the future.

CadnaB
  • CadnaB offers several manufacturer and literature databases supplying the acoustical data of the different building elements.

  • CadnaB features interoperability with CadnaA and CadnaR. The integrated software system CadnaA/B/R is currently the only system which can calculate sound from an outside source, through the construction, inside a building and through various rooms (and vice versa).
