Industrial Permitting
Compliance demonstrations for industrial facility permits and operating licenses. Predict noise impacts from manufacturing, power generation, and logistics operations.
Industrial Noise Compliance
Industrial facilities require noise permits demonstrating that operations will not exceed regulatory limits at property boundaries and nearby receptors. Noise modeling predicts operational levels before construction or equipment installation.
SoundPLAN models industrial sources using sound power levels, directivity, and operating schedules. The software calculates propagation to receivers accounting for terrain, buildings, and atmospheric conditions.
Key Capabilities
- Industrial source modeling (fans, compressors, cooling towers, stacks)
- Sound power level input from measurements or manufacturer data
- Directivity patterns for directional sources
- Operating schedule and time-of-day analysis
- Cumulative impact from multiple industrial facilities
- Compliance demonstration at property boundaries
- Before/after comparison for permit modifications
- Mitigation measure effectiveness evaluation
Industry Types
Manufacturing
Production lines, material handling, HVAC systems
Power Generation
Gas turbines, cooling towers, transformers, wind farms
Oil & Gas
Compressor stations, flare stacks, processing plants
Logistics
Warehouses, loading docks, truck movements
Permit Documentation
Industrial noise permits typically require comprehensive documentation demonstrating compliance with applicable standards.
- Baseline noise survey documentation
- Predicted operational noise levels at receptors
- Compliance demonstration against permit limits
- Noise contour maps showing impact extent
- Mitigation measures and their effectiveness
- Monitoring and verification procedures
Industrial Calculation Standards
- ISO 9613-2 - Outdoor sound propagation
- VDI 2714 - Industrial noise (Germany)
- CONCAWE - Oil & gas industry
- ISO 8297 - Sound power determination
- BS 4142 - Rating industrial noise (UK)
Source Characterization
Industrial sources are characterized by sound power level (Lw), frequency spectrum, directivity, and operating schedule. SoundPLAN supports point, line, and area source types.
- Point sources (fans, compressors, vents)
- Line sources (conveyors, pipelines)
- Area sources (cooling towers, parking lots)
- Building facades and openings
Mitigation Options
When predicted levels exceed limits, SoundPLAN evaluates mitigation options to achieve compliance.
- Equipment enclosures and silencers
- Noise barriers and berms
- Equipment relocation
- Operational restrictions (time of day)
- Low-noise equipment substitution
