Environmental Noise Modellingv1.1
DisSoniq calculates how sound from an industrial site spreads into its surroundings. Draw the sources, barriers, buildings and receivers on a georeferenced base map; the ISO 9613-2 engine returns octave-band and A-weighted levels at every receiver, a noise map over the whole area, and a report you can submit.

Key features
A complete ISO 9613-2 study, on one canvas
DisSoniq keeps the model, the map and the results together: every change on the canvas is recalculated in the background, so the noise map always matches what you see.
ISO 9613-2 engine
Octave-band propagation from 31 Hz to 8 kHz, with each attenuation term calculated separately.
Geometrical divergence
Atmospheric absorption to ISO 9613-1 (temperature, humidity)
Ground effect with ground factor G
Single-edge barrier diffraction
Sources & obstacles
Build the scene with the toolbar or keyboard shortcuts, and edit every object in the Properties panel.
Point sourceLine sourceBarrierBuildingReceiver
Spectra per object
Enter the sound power level of each source band by band; line sources carry a level per metre. Each receiver shows its total and its full spectrum as soon as the calculation finishes.
Noise maps
A calculation grid over the whole study area, at the resolution and receiver height you choose.
Contour lines, heat map, or both
DIN 18005-2 or ISO colour scale
Adjustable opacity over the base map
Georeferenced base map
Fetch OpenStreetMap or Google tiles (satellite, road, hybrid or terrain) around a centre point, with coordinates in Stereo 70 (EPSG:31700) or Web Mercator.
Reports & exchange
Hand the study over in the format each reader needs.

How a study runs
From site plan to report in six steps
Each step lives in the same window. Move a source or change a barrier height and the receivers and the map update within moments.
Step 1 · LocationBase mapCentre, extent, zoom and tile source; the map is fetched and georeferenced.
Step 2 · SourcesNoise emittersPoint and line sources with height and octave-band sound power.
Step 3 · ObstaclesBarriers & buildingsWalls and building footprints with height; building walls screen like barriers.
Step 4 · ReceiversAssessment pointsPlaced on the map or imported from CSV / KML, each at its own height.
Step 5 · CalculationISO 9613-2Temperature, humidity, ground factor, grid resolution and A-weighting.
Step 6 · ReportDocumentsWord and PDF report, KML for Google Earth, CSV tables.
Calculations run across all but one of your processor cores, so the interface stays responsive while large grids are computed. The report lists ISO 9613-1, ISO 9613-2:2024 and ISO/TR 17534-3 as its references, together with every calculation setting used.
Applications
Where DisSoniq fits
For acoustic consultants, plant engineers and authorities who need to predict and document noise at the site boundary and beyond.
01
Permits & impact assessments
Prepare the noise chapter of environmental permits and impact assessments, with levels at the nearest receivers and a map of the whole area.
02
Design & mitigation
Compare equipment layouts, enclosures and barrier heights before building, and see the effect on each receiver immediately.
03
Review & teaching
Check submitted studies against an independent ISO 9613-2 calculation, or show students how each attenuation term shapes the result.
Inside the tool
A look at DisSoniq
One industrial site followed through the application, from the scene to the finished report. Click any screenshot to see it full size.
Noise map — contour lines on the DIN 18005-2 scale, with the selected receiver's total and octave-band levels.
Results — total A-weighted level and octave-band spectrum at every receiver.
Heat map — the same field as a heat map, with a source's band-by-band sound power in the Properties panel.
Scene — sources, barriers, buildings and receivers, listed in the Objects tab.
Plant detail — the installation up close: building footprints, barriers and the sources between them.
Location — base-map centre, extent, zoom, tile source and coordinate system.
Report — the scene overview and the noise map, generated as Word and PDF.
Receiver charts — the receiver summary and a spectrum chart for every receiver.
Decision-support software. DisSoniq implements the ISO 9613-2 method; its results depend on the sound power data, geometry and settings you enter. For permit submissions, confirm the assessment method and limit values with the competent authority and have the study reviewed by a qualified acoustician.
