Industrial Noise Modelling
Predict, assess, and control noise from factories, oil & gas plants, and industrial facilities to meet environmental permit requirements across Asia and the Middle East.
Industrial Noise Assessment
Industrial facilities generate noise from a wide range of sources β rotating machinery, fans, cooling towers, compressors, and high-pressure vents. Accurately predicting how this noise propagates to surrounding communities is essential for environmental impact assessment and regulatory compliance.
SoundPLAN models each noise source individually, accounting for directivity, operating schedules, and atmospheric conditions. The software calculates cumulative noise levels at nearby receptors and generates documentation ready for submission to environmental authorities.
Key Capabilities
- Point, line, and area source modelling for complex plant layouts
- Directivity and sound power level input per ISO 3744 / ISO 3746
- Stack and vent noise propagation
- Octave-band and A-weighted calculations
- Cumulative impact assessment for multiple facilities
- Noise action plan support for permit compliance
- Before-and-after mitigation comparison
- Automated reporting for regulatory submissions
