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:

  • ISO 12354: Calculation of airborne and impact sound insulation between rooms as well as the airborne sound insulation against outdoor sound.
  • When using ISO 12354, following parameters can be calculated:
    • Performance parameters according to ISO 717-1 (airborne sound insulation) and ISO 717-2 (impact sound insulation)
    • ASTM-parameters (STC, OITC, IIC)
  • DIN 4109: Calculation of airborne and impact sound insulation between rooms as well as the airborne sound insulation against outdoor sound.

    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.
