Version number nine for noise predictor

摘要

Bruel & Kjaer's Predictor-LimA Type 7810 has added more applications with the release of the ninth version. Predictor-LimA maps environmental noise using coloured contours that can be overlaid on 3D models, photographic images, or online maps, making it easy for non-experts to understand. The new software has improved functionality and workflow support to make environmental noise mapping much simpler. It is suitable for modelling shooting ranges due to 3D source directivity, which is necessary for modelling supersonic sources.
