SoundPLAN is a modular based software package that allows the user to tailor software capabilities to their current operational requirements.  Should future modelling requirements change, the software can adapt through the purchase of additional modules.

SoundPLAN is available as a stand-alone or networked version where a single license server manages one or multiple SoundPLAN licenses to be used in a networked environment.  Pre-formulated packages are available, called StartKits, which represent good value and offer the beginner a stepping-stone into noise modelling.

SoundPLAN Essential is a low-cost single document application designed with occasional users and non-engineers in mind.  It can be used to model noise emission from roads, railways and industrial facilities utilising many features of the full version of the software but at a fraction of the cost.

The flagship is the SoundPLAN Acoustics Complete compilation which comes with a huge rebate and the assurance that future new modules will be made available without extra charge. The air pollution packages can also be added to such a license.  Multiple licenses are available at 25%, 40%, 50%, 60% discounts, depending on the number purchased.  A small surcharge is added for networked licenses.  The first year's software support, termed Upgrade and Maintenance (U & M) is included in the purchase price with subsequent years charged at 15% of the license cost in US dollars, and for SoundPLAN Acoustics Complete package this fee is capped.
