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. CadnaB has implemented the calculation methods ISO 12354 and DIN 4109.

CadnaB – The building acoustics planning system

  • 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 ISO 12354-2017 or DIN 4109. 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).
