iNoise 2018 has been released!

Dec 12, 2017

The new iNoise 2018 release includes several new powerful features such as a quick and easy calibration option for bitmaps and a very convenient option to convert sound pressure (Lp) to sound power (Lw) for point, line and moving sources. Also the sound power database has been extended with CNOSSOS-EU based sound power levels for light, medium and heavy vehicles driving 50, 80 or 100 km/hr.

New: Calibrate option for using bitmaps as background maps

The new calibrate option in iNoise 2018 makes calibration of bitmaps extremely easy. With the iNoise menu option ‘View | Background Maps’ you can add multiple GIS, CAD and Image (bitmap) files as Background map layers underneath your model. iNoise automatically recognises georeferenced image files that include a separate World file. Such georeferenced image files can be purchased or can be created with GIS software. However calibrating an image file yourself is not difficult at all. With the new intuitive Calibrate option in iNoise 2018 you can do this within seconds. Learn how to, simply by watching instruction video 6 on our website:

New: Lp to Lw option to convert sound pressure (Lp) to sound power (Lw)

With the new Lp to Lw option in iNoise 2018 for Point, Line and Moving Sources the user can now quickly determine the sound power level (Lw) of the source based on a measured sound pressure  level at a certain distance.

New: SourceDB option

SourceDB is a separate software that enables storing, searching and sorting your own sound power data, as an extension of the European IMAGINE database. SourceDB supports 1/3 octaves, a script language to define parameters and formulas to calculate the Lw and adding pictures to the sources. A sound power level in SourceDB can be easily copied and pasted in a source of an iNoise model.

New: CNOSSOS-EU sound power levels for road traffic noise

The default sound power catalogues ‘’ and ‘’ now include sound power levels for light, medium and heavy vehicles driving 50, 80 or 100 km/hr. The sound powers are taken from the CNOSSOS-EU method. In combination with the moving source item this makes it more convenient to calculate road traffic noise according to the ISO 9613 propagation.
