Our partnerships bring value and expertise to your project

We have developed a number of partnerships with key industry stakeholders. These partnerships assist us in providing advice and solutions that are tailored to your requirements.




 We are the distributing agents for the SoundPLAN noise mapping software package in Australia and New Zealand. This partnership with SoundPLAN GmbH of Germany includes provision of technical support and modelling expertise to clients.

SoundPLAN is a complete software package offering a full spectrum of noise evaluation modules, with quick and accurate calculation and impressive graphics. Comprehensive studies involving any size areas and multiple sources can be completed efficiently and cost-effectively using this modelling software.

SoundPLAN is a three-dimensional graphics-oriented program. It hosts a digitizer interface and can import bitmaps to digitize the plan. It produces colour plots and tabulations of the input data and results. SoundPLAN also includes a wall/barrier design optimization utility, an industrial noise control module and a Room Acoustics module enabling the calculation of acoustical parameters such as STI, EDT, RT, Clarity etc.

SONarchitect ISO

SONarchitect ISO was developed by Sound Of Numbers (SON) and is the most powerful software tool for calculation of sound insulation in accordance with EN ISO 12354 parts 1,2,3,4 and 6.  The software makes it possible to analyse an entire building project and automates the assessment with regards to the relevant sound insulation requirements.

SONarchitect allows the calculation of external sound insulation, internal sound insulation (impact & airborne) and Reverberation Time.  The software's DXF drawing import module allows architectural designs to be quickly built up within the software.  It has an extensive database of more than 300 constructions and this is continually expanding.  All calculations are contained within a single model resulting in efficient documentation and accreditation of acoustic designs.
