Environmental Noise Modelling

Environmental Noise Modelling

Environmental noise modelling as a tool in impact assessments

At Sound Solution Consultants (SSC) we use environmental noise modelling (or noise mapping as its sometimes known) as a tool in impact assessments. These are normally attempted where there is benefit in assessing complex scenarios, numerous sources and/or receivers, or simply to illustrate the emission from a sound source or on a receptor.

We maintain the latest version of IMMI at SSC and commonly provide environmental noise models in accordance with the following methods:

  • ISO 9613 for general use and commercial and/or industrial development
  • Calculation of Road Traffic Noise (CRTN) for highways development
  • BS 5228 for construction
  • Noise exposure in workrooms

We have the facility to upgrade our capability on noise modelling if other sources or models may be required in any application.

Environmental Noise Modelling Computer Generated Image

The pro’s and con’s of noise modelling

Noise modelling, like any technical model in science and mathematics, is dependent on the user to generate valid estimates using quality input data. The garbage-in-garbage-out (GIGO) scenario applies to modelling, because the software will only generate what the user tells it to do (and if the input data is nonsense, then the output will be nonsense!).

Certain models can also be quite time-consuming to produce, say, if considering a very large area of land or numerous sources with complex interactions with model object and the environment. At SSC we generally limit the scale of modelling to moderate objects quantities required to generate the necessary detail from any environmental noise model.

We normally use Ordnance Survey (OS) mapping suppliers for baseline imagery to include building locations and land heights which is normally suitable for an engineering estimate. However, this information can sometimes be inaccurate when considering the exacting land point or height of a building therefore we often update models to reflect Topographical Survey information, where available.

I spoke to you last Friday, Thank you very much for your advice and spending your valuable time. I am pleased with your quality because you are not a person who crushes the client with making things up for business, you are a person who looks after clients well ethical manner by giving correct and best possible advice even it does not earn financial value for you. I wish you wealthy and health better successful future ahead.


I just wanted to say a huge thank you to you and your team for all the extra help you have given me in dealing with my rather sensitive issue of noise transmission to my downstairs neighbour. It has been invaluable. In recognition, I have made a £50 donation to the charity: Action on Hearing Loss.

Jodi Riches - Client

Have worked with Sound Solution for the last 7 years and have found them to be very professional and excellent at their work. Always happy to provide me with advice pre and post purchasing new buildings and during development projects. We have worked on various scale of projects and so far have found nothing that phases them. The reports are well written, clear and easy to follow. A great asset to our extended team.

Sanjeev Bhamm, Pelham Associates

We are delighted to work with SCC Ltd in resolving the ever more complex requirements for careful acoustic design. Their knowledge coupled with a helpful approach assists us in delivering tailored solutions which fit within our design constraints.

Chris Parsons, Parsons Whittley

We have been working with Sound Solutions for a few years now, as they offer a professional and consistent service. They are always happy to respond to site-based questions and are quick to reply to emails and phone calls. It is reassuring to our clients that they provide both the specification prior to construction and test on completion.

Ben Harvey - Architect, Liam Russell Architects

We have worked with Mark and the team at Sound Solutions for many years and have always been very happy with their professional service and first-rate advice. I have personally recommended them to many other clients.
