The noise3D online program calculatesÂ outdoor sound propagation in accordance with Directive ISO 9613 (Part 1 and 2).Â Modeling is performed using theÂ Trimble Navigation SketchUpÂ®Â program. Below the functionality of the acoustic modeling program is described.Â Software manuals and instructional videos for SketchUpÂ®Â are available on the manufacturer website. Furthermore, the relevant guidelines for the calculation andÂ assessment of environmental noise are referenced.
The present version of noise3D online has been developed to calculate industrial and commercial noise.Â A module targetting traffic noise (road / rail) is planned for future development.
The various acoustic elements are stored in different layers, each of which areÂ created automatically during the digitization process. All acousticÂ layer names end with _KS. The following is aÂ list of primaryÂ layers.Â Any number ofÂ layers may be developed and used in the modeling. Names are listed as layer names, then model element.
|AreaSource_KS||horizontal surface source|
|vAreaSource_KS||vertical surface source|
