International Noise Standards — 50+ Calculation Methods Supported by SoundPLAN
SoundPLAN supports the most comprehensive collection of international and national noise calculation standards of any noise modeling software. With over 50 recognised methods covering road traffic, railway, aircraft, industrial, and occupational noise, SoundPLAN is the preferred choice for multi-national consultancies, international project developers, and any organisation whose work requires compliance with multiple regulatory frameworks across Asia, the Middle East, Europe, and beyond.
The modular architecture of SoundPLANnoise means you can start with the calculation standards relevant to your current market and add new methods as your project portfolio expands — without having to switch software or retrain staff.
Road Traffic Noise Standards
Road traffic noise assessment is the most common acoustic study type in Asia and the Middle East, required for EIA, urban planning, and infrastructure project approval. SoundPLAN covers every major international road noise method:
- RLS-90 and RLS-19 — German road traffic noise standards, widely referenced in Asian EIA practice and frequently specified by international development banks
- NMPB / XP S 31-133 — French national method, also the basis for CNOSSOS-EU road calculations
- CRTN and CoRTN — UK Calculation of Road Traffic Noise, used in former British territories including Singapore, Malaysia, and Hong Kong
- Nordic — Scandinavian national calculation method for road traffic noise
- TNOISE — Swiss national road noise method
- TNM — US Federal Highway Administration Traffic Noise Model
- CNOSSOS-EU — The European Common Noise Assessment Method, required for all EU strategic noise mapping
Railway Noise Standards
Rail infrastructure projects — metro systems, high-speed rail, light rail, and conventional rail — all require noise assessment. SoundPLAN supports:
- Schall 03 — German railway noise calculation standard, frequently specified in Asia for major rail projects
- RMR — Dutch railway noise method (Reken- en Meetvoorschrift Railverkeerslawaai)
- Nordic Rail / RailNoise — Scandinavian methods for rail noise assessment
- CNOSSOS-EU railway — European standard method for strategic railway noise mapping
Aircraft Noise Standards
- ECAC Doc.29 — European standard for aircraft noise modeling around airports (3rd edition), used for airport land use planning and noise action plans
- FAA INM (Integrated Noise Model) — US Federal Aviation Administration standard for airport noise contours
- FLULA — Swiss aircraft noise prediction methodology
- AEDT — Aviation Environmental Design Tool
Industrial & Environmental Noise Standards
- ISO 9613-2 — International standard for the attenuation of sound during propagation outdoors. The most widely used method for industrial and general environmental noise assessments worldwide.
- ISO 8297 — Determination of sound power levels of large machines for environmental noise prediction
- VDI 2714 / VDI 2720 — German methods for outdoor sound propagation and noise barriers
Occupational Noise Standards
SoundPLANmanda supports ISO 9612:2009 (occupational noise measurement and exposure calculation) and ISO 1999:2013 (noise-induced hearing loss estimation), alongside regional occupational noise regulations across Asia and the Middle East.
