SoundPLAN 9.1 is the world's leading software for the prediction, calculation, mapping, and assessment of environmental noise. Trusted by acoustical consultants, government agencies, and researchers, it is the definitive tool for conducting noise impact studies, creating legally required strategic noise maps (under the EU Environmental Noise Directive), and designing effective noise control measures. SoundPLAN integrates advanced acoustical calculation methods with powerful GIS functionality to model noise from all major sources—including road and rail traffic, industrial plants, airports, and wind farms—providing a complete solution for noise management and urban planning.

 Core Functional Capabilities of SoundPLAN 9.1

• Multi-Source Noise Modeling & Prediction
  Model complex noise environments with precision. The software includes certified calculation methods for road traffic (RLS-90, CNOSSOS-EU, FHWA), railway noise (Schall 03, CNOSSOS), industrial noise (ISO 9613-2, VDI 2714), and aircraft noise, allowing them to be combined in a single project.

• Advanced 3D GIS-Based Calculation & Mapping
  Work with real-world terrain and building data. SoundPLAN uses detailed 3D topographic models and building footprints to accurately calculate sound propagation, including effects of diffraction, reflection, and atmospheric absorption. It generates high-resolution noise contour maps and facade level grids.

• Compliance with International Standards
  Ensure your studies meet regulatory requirements. SoundPLAN 9.1 is fully compliant with the EU CNOSSOS-EU framework for strategic noise mapping and supports a vast array of national and international calculation standards, making it the go-to software for official submissions and Environmental Impact Assessments (EIA).

• Detailed Assessment & Mitigation Design
  Go beyond simple prediction. The software includes tools for evaluating population exposure, comparing scenarios against noise limit values, and designing noise barriers or building insulation schemes. It can calculate the acoustical performance and cost-effectiveness of various mitigation options.

 The SoundPLAN Advantage in Noise Control

In a world increasingly focused on environmental quality and public health, accurate noise assessment is paramount. SoundPLAN 9.1 sets the industry standard through its unparalleled combination of scientific rigor, computational power, and practical workflow tools. Its ability to handle large-scale urban areas and complex industrial sites with consistent accuracy makes it indispensable for consultants who need to deliver reliable, defensible results to clients and regulators. For any project where sound is a factor—from a new highway to a residential development near an airport—SoundPLAN provides the authoritative analysis.
