Guide · Noise visualisation software - Noise visualisation software for workplace compliance
“Noise visualisation software” usually means a modelling licence you run yourself. A delivered 3D noise map is a different thing — and for compliance, the difference matters.

Search for “noise visualisation software” and most results are generic acoustic modelling packages — licences you install and run yourself, building a model from a floor plan and your own assumptions about sources and materials. AcoustaPLOT Noise Mapper is a different kind of thing: a delivered 3D noise map, built from a real on-site survey by the same team that carries out your Noise at Work Assessment, not a tool you operate alone.
Why the distinction matters for compliance
A generic modelling licence is only ever as accurate as the data you put into it — source levels, room materials, machine positions — all assumed or estimated by whoever is driving the software. For a compliance document that may be relied on by a board, an insurer, or an HSE inspector, that is a real gap. A delivered map starts from genuine Class 1 measurements taken on your floor, run through the same propagation and transmission physics as a standard written assessment, so the visual and the legal record can never disagree.
| Generic modelling software | AcoustaPLOT Noise Mapper | |
|---|---|---|
| Who operates it | You, from a licence | The assessment team, on site |
| Source data | Assumed or estimated | Measured, Class 1 survey |
| HPZ boundaries | Manually drawn | Derived from the measured contour |
| Output | A model file | A finished map, report and (optional) flythrough |
What you actually get
Every map is built on the same tool used to run the survey itself — Measured mode interpolates a continuous noise surface from real LAeq pin readings; Predicted mode models sources, enclosures and barrier screens for planning a change before it’s built. Boundaries and scale are traced and calibrated against your own uploaded floor plan, not a generic shape. The result is delivered as a 2D plan with dB contour lines, a 3D landscape, and — on the higher tiers — an interactive 3D model or a rendered flythrough video, with Hearing Protection Zones marked throughout.
Who this is for
Architects & acoustic consultants
Assessing a space
A measured model of an existing floor, or verification that a design change actually worked once it’s built.
Insurers
Documenting control
A clear, defensible visual record of noise control, sitting alongside the written assessment rather than instead of it.
Facilities managers
Briefing a multi-site estate
A consistent, comparable visual format across sites, without needing to operate modelling software in-house.
It’s worth being direct about what this isn’t: not an AI-generated illustration, and not a substitute for the written Noise at Work Assessment and the duties that come with it. It’s the readable layer built on top of real, defensible numbers — see 3D noise mapping explained for the full picture.
Pricing
Priced by tier and floor size, from £750 + VAT (Standard, up to 3 rooms) to £1,350 + VAT for Photoreal with a rendered flythrough, with a fixed per-room rate above 3 rooms. See the full 3D noise mapping overview for the complete tier breakdown.
