Sound absorption coefficient calculation software
The ZORBA software is a tool for calculating the sound absorption coefficient of porous materials and perforated surfaces. ZORBA is currently available in version v3.0 with a German user interface and is developed by Marshall Day Acoustics.
ZORBA - Demo version / 30-day license
The demo version of ZORBA is available for free download. In demo mode, however, the material selection is random.
For practical calculations, we provide a valid, time-limited software key on request which allows the full range of functions to be tested. A new download is not necessary.
