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 via the façade walls.
  • 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 via the façade walls.

    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.
