Noise Prediction for Industry and Wind Turbines

iNoise is the new intuitive and quality assured software for industrial noise calculations in the environment. The calculations are based on the ISO 9613 method and the recommendations of the new quality standard ISO 17534. The GUI is based on the Windows design rules for a genuine Windows user experience.

Quality assured software

The ISO 9613 standard from 1996 is the most used noise prediction method worldwide. Many countries refer to ISO 9613 in their noise legislation. However the ISO 9613 standard does not contain guidelines for quality assured software implementation, which leads to differences between applications in calculated results. In 2015 this changed with the release of ISO/TR 17534-3. This quality standard gives clear recommendations for interpreting the ISO 9613 method. iNoise fully supports these recommendations. The models and results for the 19 test cases are included in the software.

iNoise supports the quality assurance interface (QSI format) for exchanging model data with other noise prediction software.

I found it really easy to get to know the program using the ‘Getting Started’ guide.  I found the menu’s and functions very intuitive.  I typically found that when I thought a function should exist, it did and it was where I expected it to be.

Advanced import, editing and result display

File formats: SHP/DXF/DWG/GMF/MIF/TXT/QSI, (Geo)TIFF/BMP/JPG/PNG/WMF, WMS (Web Map Services) Edit: 2D/3D/cross section, thematic display, copy/paste, paste as other item, undo/redo, snap/move/rotate/rescale, parallel items, break/connect/merge/clip/simplify polylines and polygons. Results: horizontal/vertical (façade)/cumulated/difference contours, ranking/what if/compare models.

Advanced modelling items

Sources: point/line/area source, vertical area source, moving source, wind turbine, emitting façade/roof. Objects: (floating) building, (floating) barrier (with transmission), ground/foliage/housing region, industrial site. Terrain model: height line, height point. Calculation point items: receiver (with up to 5 heights), horizontal grid, vertical grid, contour point (for irregular grids)
