Calculation

CadnaB calculates the airborne and impact sound transmission in third-octave band width and for single number values. The software is designed to implement any national standard in the future.


Calculation Standards

The following standards are implemented in CadnaB:

  • Calculation of airborne sound insulation between rooms
    according to ISO 12354-1, 2017
  • Calculation of impact sound insulation between rooms
    according to ISO 12354-2, 2017
  • Calculation of airborne sound insulation against outdoor sound
    according to ISO 12354-3, 2017
  • Calculation of all performance parameters according to ISO 717-1 (airborne sound insulation) and ISO 717-2 (impact sound insulation) available
  • Calculation of ASTM-parameters (STC, OITC, IIC)

Implementation of new standards

Thanks to the CadnaB´s design phylosophy, further calculation procedures and national standards will be implemented in the future, allowing the extensive use of the software no matter where it should be applied.
