Industrial noise modeling predicts how noise from factories, refineries, power plants, chemical plants, and other industrial facilities propagates to the surrounding community. Accurate prediction is essential both for permit compliance — demonstrating that noise levels at the site boundary and at sensitive receptors will not exceed applicable limits — and for designing effective noise control measures before construction or during operations.
SoundPLAN uses ISO 9613-2 as its primary calculation engine for outdoor industrial noise propagation, supplemented by ISO 8297 for large complex industrial sites and VDI 2714/2720 for German regulatory requirements. The software handles the full complexity of industrial noise prediction: multiple simultaneous sources, directional emission, terrain and building shielding, reflections, and barrier effects.
A typical industrial noise assessment with SoundPLAN follows this workflow: first, define all significant noise sources with their sound power levels (from measurement data or manufacturer specifications); second, build the 3D facility geometry including buildings, terrain, and barriers; third, run the ISO 9613-2 calculation to generate community noise contour maps and receptor noise levels; fourth, compare predicted noise levels against applicable limits; and finally, design mitigation measures as needed. SoundPLAN Asia can assist at any stage of this process — from initial model setup to finalising the regulatory submission.
