Noise Modelling
Calculation-based acoustic modelling that predicts how noise will propagate through the environment, helping assess the impact of planned or existing activities and identify effective noise-reduction measures before costly decisions are made.
Acoustic Modelling
What Is Noise Modelling?
Noise modelling uses mathematical calculations to predict how sound propagates from one or more sources through the surrounding environment.
Unlike a noise measurement, which records actual sound levels at specific locations, modelling can predict noise conditions before a project is built or changed. This makes it useful for planning, environmental assessments, industrial development and infrastructure projects.
The model can account for:
- Noise source power and location
- Source height and operating conditions
- Terrain and ground characteristics
- Buildings and other screening structures
- Road and railway traffic
- Relevant meteorological conditions
- Day, evening and night operating periods
- Operating regimes and day/evening/night periods
Use Cases
When Is Noise Modelling Needed?
Noise modelling can help when you need to:
- Assess the impact of a planned industrial facility
- Plan logistics centres, warehouses or commercial developments
- Assess road and railway infrastructure
- Prepare environmental impact assessment documentation
- Support territorial planning and development decisions
- Assess noise from wind turbines
- Determine the likely impact of new equipment or engineering systems
- Investigate potential noise impacts on nearby residential areas
- Design and assess noise-reduction measures
- Compare different development or mitigation scenarios
Pricing
How Much Noise Modelling Costs?
From €480 + VAT per project
The final price depends on the size and complexity of the model, number of noise sources, modelling area, available input data and required analysis.
We review your project requirements first and confirm the scope, deliverables and price before work begins.
Capabilities
What We Model
Industrial Noise Modelling
Noise propagation from factories, production facilities, logistics centres, quarries, wastewater treatment plants and energy facilities. Models can assess different equipment loads and operating scenarios and show predicted noise levels across the surrounding area.
Road Noise Modelling
Assessment of noise from road traffic based on traffic volume, vehicle speed, road characteristics, terrain and other relevant factors. Models can also assess the potential effectiveness of noise barriers and other mitigation measures.
Railway Noise Modelling
Assessment of noise from railway infrastructure based on factors such as train frequency, speed, track characteristics and operating conditions. Results can show predicted noise levels around existing or planned railway infrastructure.
Wind Turbine Noise Modelling
Assessment of noise propagation from wind turbines and wind farms, including the contribution of multiple turbines and their potential impact on nearby residential areas.
Engineering-System Noise Modelling
Prediction of noise from ventilation, air-conditioning systems, heat pumps, generators, lifts, pumps and other technical equipment before installation or modification.
Residential Noise Modelling
Assessment of noise levels affecting homes and residential developments, including noise propagation around buildings and gardens. Models help identify potential impacts and required mitigation measures.
Deliverables
What Does a Noise Modelling Study Include?
Depending on the project scope, deliverables can include:
- Noise propagation maps
- Predicted noise levels at relevant locations
- Assessment against applicable noise limits
- Different operating or development scenarios
- Identification of areas potentially affected by excessive noise
- Assessment of proposed noise barriers or other mitigation measures
- Technical calculations and supporting documentation
- Conclusions and practical recommendations
Combine Noise Modelling with Acoustic Camera Investigation
For complex industrial sites with multiple potential noise sources, modelling can be combined with acoustic camera investigation.
The acoustic camera can help identify and locate dominant sources on site, providing additional information that can be used alongside measurements and modelling where appropriate.

The Process
How Noise Modelling Works
Provide Project Information
We collect site plans, topographic information, noise-source data and other available project documentation.
Define the Model
We establish the relevant noise sources, operating scenarios, assessment area and applicable requirements.
Build & Run the Model
Our specialists create the acoustic model and calculate predicted noise propagation under the relevant scenarios.
Assess the Results
We compare predicted noise levels with applicable limits and identify potentially affected areas.
Receive the Results
You receive the modelling results, maps, technical documentation and recommendations included within the agreed project scope.
