Noise Modelling
Noise modelling is a technical process used to predict how sound travels and affects people and places before a development is built or operational. Within the UK planning system, noise modelling provides a robust, evidence-based method for assessing potential noise impacts and demonstrating compliance with planning policy and recognised standards.
How does Noise Modelling work?
We use industry-leading noise modelling software to provide accurate prediction and assessment of noise impacts within complex planning environments.
3D Noise Modelling
3D Noise modelling is used to create detailed three-dimensional geographical noise models that simulate real-world sound propagation across a site and surrounding area. This approach allows us to:
- Predict noise levels at existing and proposed receptors
- Assess cumulative impacts from multiple noise sources
- Model future scenarios and operational phases
- Test different design scenarios
- Test and optimise mitigation measures prior to implementation
- Produce clear noise contour maps and visual outputs for planning submissions
3D modelling is particularly valuable for major developments, complex sites and schemes subject to detailed scrutiny by local authorities. The results are typically presented as noise contour maps, façade level predictions and internal noise assessments. These outputs allow planners and Environmental Health Officers to understand potential impacts clearly and ensure developments align with the objectives of the National Planning Policy Framework (NPPF) and Planning Practice Guidance on Noise.
Façade Sound Insulation Modelling
Industry Standard software is used to assess façade sound insulation performance and internal noise levels within buildings. This enables us to:
- Determine glazing specifications
- Demonstrate compliance with internal noise criteria
- Support design decisions at planning or early design stages
- Provide clear evidence for condition discharge
In short, modelling provide robust, transparent and repeatable evidence to support planning applications and negotiations with regulators.
