A very flexible package with no restrictions on model size and with a full range of international standards.  The standards most commonly used in the UK, Calculation of Road Traffic Noise (CoRTN), Calculation of Rail Noise (CRN),  BS5228 (Noise and Vibration Control on Construction and Open Sites), ISO 9613 (Acoustics - Attenuation of sound during propagation outdoors - Part 2) and Concawe are all included as standard.

SoundPLAN is modular so you can buy  modules for your specific needs and you can add modules at any time to allow you to increase your range of projects.

Superb 2D, 3D and animated graphic output. 

Tabular output giving options ranging from simple noise level results for any defined time periods to a full breakdown of source contributions with details of applied corrections etc. allowing you to understand in detail how results have been obtained.

Spreadsheet allowing detailed analysis of results and automation of analysis such as DMRB (Design Manual for Roads and Bridges).

Run details are recorded in results files allowing full traceability of the results to ISO 9000.

Powerful Tools for Assessment and Selection of Alternative Mitigation Measures.

Projects can contain many 'situations' which simplify "what if " analysis which may or may not share data as required.  Changes to objects can apply to all or only one situation.
