Noise & Vibration Modelling
Modelling is one of the only ways in which the scale of a noise and vibration issue can be understood and the cost-effectiveness of noise control and mitigation measures can be determined. Using GIS, modelling outputs can be used to help understand the health effects of noise and vibration.
Noise Consultants use sophisticated noise and vibration modelling tools that harness digital mapping, drawings and demographic datasets to develop 3D models of existing and future environments. Within these models, noise and vibration propagation calculations can take place, allowing the effect of noise and vibration to be understood along with the measures that best serve to control their propagation.
Our consultants have a background in large area noise mapping and modelling projects. Our experience includes noise modelling of:
- Aircraft and aviation sources
- Road and highway infrastructure
- Light and heavy rail
- Industrial operations
- Military infrastructure
We have developed tools, processes and workflows that have increased modelling efficiency which allows noise modelling to be deployed without significant cost to even the smallest of projects.
Our tools and processes allow for:
- Model Validation – a process of calibrating our models to reflect real-world measured levels and/or the outcome of long-term surveys;
- Calculated Emissions – gathering and processing information to enable the calculation of noise emissions, namely for roads and railways using methodologies such as the Calculation of Railway Noise (CRN) and the Calculation of Road Traffic Noise (CRTN); and
- Individual Noise Events – calculation of noise levels as a result of noise events rather than noise exposure.

Noise & Vibration Mapping
Noise mapping is an extremely helpful tool in understanding how populations and locations of interest are affected by noise. This information is now being used by government and local authorities as a scoping tool and can be used to quantify health outcomes using dose-response relationships. It has also become a key driving factor in the development of local and national noise policies. Strategic noise mapping and the preparation of Noise Action Plans are required every 5 years under European legislation. Away from legislative requirements, noise mapping is becoming an approach that is readily adopted in the description and quantification of baseline conditions as part of an Environmental Impact Assessment.
Noise Consultants have the noise modelling and GIS capabilities to prepare and analyse noise maps at a local and national level.
Building on our noise and vibration modelling expertise, and our wider service portfolio, we offer specialist GIS services that can assist in identifying the scale, location and effects of noise and vibration on sensitive receptors.
These services include:
- Noise Mapping and Publishing – presenting noise exposure using cartographic, interactive and online mapping tools. We have tools that allow noise exposure information to be made more accessible through tools such as Google Earth;
- Noise Effect and Monetisation (WebTAG) Outcomes – the calculation of noise effect outcomes using dose-response relationships to identify how conditions, developments or infrastructure may be affecting human health. This is an increasingly important area within the context of Environmental Impact Assessment (EIA) and noise policy. Our tools can be used to assist with Health Impact Assessments.
- Visualisation – presenting noise exposure information beyond simple noise contours and tables including 3D views, presentation of non-acoustic information alongside noise outcomes and noise event simulations; and
- Data Processing – development of workflows and processes that enable forms of digital data used to generate noise exposure to be used in modelling and analysis. This includes datasets such as noise complaint histories, flight tracks, diurnal operating patterns, social surveys and demographic datasets.
Noise & Vibration Measurement
We have experience in undertaking noise measurements of a variety of sources. Detailed measurement work is often required when information about a noise source is not readily available and is required for assessment purposes, or where an understanding of the noise and/or vibration being emitted by a source is necessary for demonstrating design or planning compliance or for investigating complaints.
Our measurement services are tailor made to the end-requirement. Our consultants have been involved in designing noise measurement surveys for sources such as aircraft, military activities and noise nuisance cases. We have access to the latest noise and vibration instrumentation and stipulate where such work will be needed to meet our client’s requirements.
Noise & Vibration Monitoring
Monitoring allows noise and vibration levels to be understood over a period of time, whether the main source is known or not. Monitoring is typically used for a number of purposes:
- Baseline Monitoring – which can be used to determine the suitability or otherwise of a location for noise sensitive development or the potential sensitivity of a receptor to a change in their noise and/or vibration exposure;
- Compliance Monitoring – monitoring of noise from potential constant and disruptive noise generating activities such as construction work and wind farms, including the provision for noise limit triggers and alerts;
We have experience in developing, implementing and reporting noise monitoring exercises for projects in sectors including construction, defence and transportation. We have access to noise monitoring equipment that enable noise and vibration levels to be recorded over periods of hours to months.
