A new age for building acoustics.
With SONarchitect it has been possible for the first time to analyse the sound insulation performance of an entire building project, and with direct comparison to the relevant sound insulation requirements.
The user interface is very good, and the calculation time is close to nil, even for very big projects. Details on a single transmission path or the statistical overview for all calculation results - both are easily accessible. SONarchitect has set a mile-stone in computer modelling and brought building acoustics to a new age.
With a glance to the ongoing fast development in 3D design and modelling tools for architects, this software means a very big step forward in the direction of integrated Building Information Modelling (BIM) also for building acoustics.

SONarchitect ISO calculates:
- Airborne noise insulation values according to EN 12354-1.
- Impact noise levels according to EN 12354-2.
- Façade acoustic insulation values according to EN 12354-3.
- Noise emission levels from noisy enclosures according to EN 12354-4.
- Reverberation times in rooms according to EN 12354-6.
Also performs the Metzen approximation.
For analythic calculation of sound reduction index (and impact noise level) SONarchitect ISO includes SONmultilayer, with the matrix transfer function method, and SONequation with the methods referenced in:
