Product Selection Guide

Which SoundPLAN do you need?

It comes down to one question: what are you being asked to produce? Noise levels at receptors outside a site, or noise exposure for the people working inside it. Those are different jobs, different standards and different software.

Noise OUTSIDE the site

Levels at homes, schools or the site boundary — for an EIA, an operating permit, a planning application or a strategic noise map.

SoundPLANnoise

or SoundPLANessential if the projects are small and occasional

Exposure INSIDE the facility

What workers are exposed to over a shift, under ISO 9612, for a hearing conservation programme or an OSH audit.

SoundPLANmanda

a different tool for a different job, not a cheaper version

Both

Common for industrial clients, who answer to an environmental regulator at the boundary and a safety regulator on the shop floor.

Choosing between SoundPLANnoise and SoundPLANessential

Both use the same calculation core, so the numbers agree. The split is scale: SoundPLANessential is a single-window application for smaller models on a single workstation; SoundPLANnoise is modular, handles large models with distributed computing across several machines, covers 50+ standards, and allows unlimited installations on one network.

If you are unsure, starting with Essential carries no penalty: the full amount you pay for it is deducted from the cost of upgrading to SoundPLANnoise later. SoundPLANessential+ sits between the two, adding railway noise, strategic noise mapping and EU END compliance.

The one thing worth confirming before you buy is the calculation standard your assessment has to be reported against — see the supported standards.

Sound Particle Diffraction (SPD)

Only available with SoundPLAN — no competitor offers this capability

What is SPD?

SPD is SoundPLAN's proprietary indoor sound propagation method. Unlike conventional geometric methods limited to 1-2 diffraction edges, SPD accurately calculates sound diffraction around any number of edges and obstacles.

  • Multi-edge diffraction — unlimited diffraction paths
  • Combined specular & diffuse reflections
  • Reverberation time calculation

Why It Matters

ISO 9613-2 shows discontinuities when switching from single to double diffraction. SPD handles unlimited diffraction paths with Nord2000-level accuracy, validated against wave-based theory and real measurements.

  • Measurement-validated in semi-anechoic chambers
  • OpenCL GPU acceleration for fast calculations
  • Complex room geometries handled accurately
