Predictor-LIMA
Maps how noise from a road, railway or factory actually spreads across a neighbourhood.
What it is
About Predictor-LIMA
Predictor-LIMA is environmental noise prediction software used to model and map noise propagation from sources such as roads, railways, industrial sites and airports across large geographic areas, incorporating terrain, barriers, buildings and meteorological effects. It's used to produce noise contour maps for planning applications, environmental impact assessments and statutory noise mapping (e.g. under the Environmental Noise Directive), calculating exposure using standard methods like CRTN, CRN and CNOSSOS-EU. It competes directly with CadnaA and SoundPLAN in the environmental acoustics consultancy market.
What you can do with it
Capabilities
Model noise propagation from road, rail, industrial and aviation sources
Produce noise contour maps for planning and environmental impact assessments
Calculate noise exposure using standard methods (CRTN, CNOSSOS-EU, ISO 9613)
Assess the effect of noise barriers, terrain and buildings on propagation
Support statutory noise mapping and action planning requirements
How to learn it
Learning Resources
Institute of Acoustics courses on environmental noise assessment and mapping
Software vendor training (distributor-run courses, depending on current regional supplier)
Practise on sample datasets provided with the software licence
Environmental acoustics consultancy on-the-job training, since most learning happens on live planning projects
Pro Tip
Get your source and terrain data quality right before trusting the output contours — noise mapping software is only as accurate as the traffic flow, terrain and building height data fed into it.
