ZORBA is software for sound absorption predictions of porous absorbers with different types of facings, developed by Marshall Day Acoustics, Nya Zealand.
ZORBA is software for prediction of the sound absorption of building elements written by Marshall Day Acoustics in New Zealand. The software can calculate sound absorption of:
- One- and two-layered porous absorbents. The only input that is needed is thickness and flow resistivity.
- Slat absorbers on one- or two- layered porous absorbers. Variable dimensions of slats and ribs.
- Slot absorbers on one- or two- layered porous absorbers. Variable dimensions of slots and ribs
- Perforated facings on one- or two- layered porous absorbers. Variable dimensions of perforation
- Panel absorbers on one- or two- layered porous absorbers. Variable dimensions of panel.
- Acoustic blanket
The predictions are based on analytical calculations that only need simple data for the design.
The software calculates the statistical absorption coefficient in third octave bands with random or normal angle of incidence and the complex acoustic impedance. It also can predict the transmission loss of porous material.
For deeper analysis the software includes nine different propagation models.
Data can be exported to Word, Excel or as pdf.
ZORBA is a powerful tool for fast and accurate design of absorption characteristics that meets the demands of most applications.

ZORBA is locked with a hardware USB-dongle. The software can be installed on an unlimited number of computers, but the dongle has to be moved. There is also a network version available, where ZORBA and the dongle are installed on one of the computers on the network. ZORBA can be operated from all computers connected to the network up to a limited number of users.
