The building acoustics planning system
CadnaB Overview
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 via the façade walls. CadnaB has implemented the calculation methods ISO 12354 and DIN 4109.
Apply CadnaB to calculate airborne and impact sound transmission between rooms for an entire building including airborne sound transmission from and to the exterior via the façade walls.
CadnaB offers several manufacturer and literature databases supplying the acoustical data of the different building elements.
Calculation according to ISO 12354-2017 or DIN 4109.
CadnaB features interoperability with CadnaA and CadnaR. The integrated CadnaA/B/R software system is currently the only system that can calculate sound from an outside source through building structures into a room (and vice versa) as well as between different rooms.

CadnaA calculates outdoor/environmental noise (road, rail, industry, aircraft and city noise mapping). CadnaB handles building acoustics (airborne and impact sound insulation for whole buildings). CadnaR predicts room and indoor acoustics such as reverberation time and speech intelligibility. Together they form one integrated platform.
Typical applications include sound insulation verifications under DIN 4109 and ISO 12354, planning airborne and impact sound insulation between and within dwellings, the acoustic design of hotels, office and school buildings and healthcare facilities, and assessing protection against outdoor noise through the façade — from individual room pairs up to the whole building.
