Brüel & Kjaer launch updated noise-mapping software

Predictor-LimA software package offers several new features and improved user support

SOUND and vibration specialists Brüel & Kjaer have made environmental noise mapping much simpler with a more user-friendly version of their Predictor-LimA 7810 software.

This latest 8.1 version has an improved data-handling system, an intuitive Windows-based graphical user interface and integrated project organization options for scenario management and archiving duties.

Predictor-LimA also has improved user support, including a closed website with a frequently asked questions (FAQ) section, downloads, license files and instruction videos. It has several new functions, including the recently updated NMPB-2008 method (French road traffic noise method) for calculation of road traffic noise.

In addition, the US TNM road noise method is implemented, which is said to provide significantly faster calculations than the TNM software, with the same quality of results. A wind turbine catalogue option, which meets ISO 9613 methods, allows measured data and information from manufacturers to be stored and retrieved, allowing consultants and utility firms to perform calculations of noise from wind farms.

This combined version integrates both the Predictor and LimA tools into a single powerful software suite. It can accurately model real life, even in complex situations, such as testing road flyovers with noise barriers, allowing regular and infrequent users to work more efficiently.
