Cambridge Environmental Research Consultants are one of the UK’s leading consultants on urban environmental issues. Over the past 5 years we have assisted over 70 UK local authorities with their review and assessment of air quality. We are now pleased to offer a noise mapping service consistent with DEFRA and EU requirements. Although relatively new in the UK, noise mapping is a well-established practice in many European countries. It is an integral part of the process of developing an ambient noise strategy, and for ensuring that current and future noise levels are in compliance with existing UK and EU legislative standards. 
Example noise map: A busy road junction in the London Borough of Southwark, illustrating the screening impact of buildings, and the increased levels around major intersections. The receptor points where modelling results may be compared to monitored noise levels are shown. Map produced using CadnaA noise mapping software (DataKustik GmbH http://www.datakustik.de). Based on advanced noise mapping software and our experience in developing noise propagation models, we offer an integrated service, combining the impact of all ambient noise sources: road, rail, industry and aircraft movements. The results will allow an analysis of the individual and combined effects of all these sources, for daytime, evening and night-time periods. Our package of results includes not only the completed and validated noise maps, but also the noise emission data. Much of this can be supplied in a format for easy manipulation, so that local changes and new planning scenarios can be generated. The results can then be exported ready for modelling both their noise and air quality impacts. For example this could be used for an assessment of the noise impacts of any proposed Air Quality Action Plan. The most demanding and costly task in noise mapping is obtaining and processing the required input data. CERC’s experience in working with emissions data for dispersion modelling allows us to undertake this more easily. We will seek to use data that has already been purchased or developed for air pollution work, which will ensure consistency with these studies and reduce costs. We are also working with third party suppliers of geographical and primary activity data sets to ensure the availability of high-quality information in the appropriate format.
