- Version LimA - Environmental Noise Modeling and Mapping Software


Work more efficiently on a wide variety of environmental noise mapping projects with Predictor-LimA’s extraordinary calculation speed. Save time and reduce your investment in computing power with the versatile software.


The powerful software enables you to assess environmental noise for:

  • Prediction of future levels
  • Comparison of alternative noise reduction scenarios
  • Levels to be assessed even when contaminated by high background noise, such as an industrial plant in the vicinity of a busy road
  • Production of noise contour maps from one or more sources including roads, railways, industries, construction sites and airports
Environmental noise mapping, modeling, calculating and predicting
  • Improve urban noise mapping capabilities with rapid calculation speed and capacity
  • Unique macros support automation of geometrical processing to more easily and quickly make acoustic models
  • Efficiently predict and report on environmental noise pollution with powerful result analysis and what-if scenarios
Action planning and noise impact assessment
  • Quickly process massive volumes of survey data for a variety of purposes, including reporting
  • With all scenarios and action plans in one project, avoid time lost searching for correct files on the network
  • Fulfill legislative requirements including the European Environmental Noise Directive (2002/49/EC) and the IPPC Directive (2008/1/EC)
