We have a huge amount of experience in dealing with BS8233 Noise Assessments for noise reduction in new buildings and BS4142 Industrial Noise Survey Assessments for industrial noise to satisfy our clients planning application/s on all types of developments.
Here is a quick description for each type of noise survey:
BS8233 Noise Survey
More often than not, noise assessments are requested in relation to the planning conditions on new build apartments, houses, or hotels. The assessment is required at the planning stage because the local authority want to ascertain what extra noise may be generated by the proposed development.
Residential developments can be affected by various noise sources, such as transport noise, entertainment noise and industrial noise sources. We have undertaken hundreds of successful noise surveys on residential developments supporting planning consultants, architects, construction companies and private individuals to ensure the most practical and cost effective acoustic solutions are implemented at the design stage. We have worked on all types of projects from small dwellings right up to the largest apartment blocks.
When applying for full planning permission, you may require an acoustic assessment and noise survey of your development to ensure it is suitable for residential development. This is a requirement under the National Planning Policy Framework in England and Wales. The purpose for the acoustic assessment and noise survey is to protect the future residents from noise and provide good acoustic conditions both internally through an appropriately designed building envelope and externally in gardens etc. via acoustic fencing etc.

BS4142 Noise Survey
If you have received a planning condition requiring a plant noise survey in accordance with BS4142 we can help. We recognise that noise from industrial sites is playing an ever-growing role with planning authorities. The Central Government’s push to promote re-development of brown field sites is increasingly pushing together industrial and residential developments, where industrial noise levels and operating hours may pose a serious harm to amenity and quality of life.
Local authority control on noise emissions via planning can mean that the insulation of plant & machinery can be an important part of achieving sound pressure level limits, either at the site boundary or at nearby local sensitive receivers. Establishing guideline noise levels and limits and monitoring the compliance with those limits is often a crucial part of that process.
If you are introducing a new noise source to your project, we would measure the existing levels in the area over 24 hours, and predict the impact of the potential new noise source. If the noise source is already be present, we can measure the noise levels over 24 hours without the noise source and then again with the noise source to establish the difference.
BS4142 provides the method of assessing industrial noise in areas where there is existing housing. The existing background noise is measured (at different times of the day if necessary) using the measure LA90. This is the level exceeded for 90% of the time. Our consultants are extremely familiar with the methods and requirements of BS4142.
We can offer a detailed survey report and outline possible mitigation measures with noise mapping to show the ‘real life’ effectiveness of the measures. Such assessments can cover extraction systems, air conditioners, industrial plant, refrigeration units, and general use of industrial buildings.
