We at APT Sound Testing 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.
We provide full compliant BS4142 Industrial Noise Surveys using the latest ‘state of the art’ Norsonic acoustic equipment.
If the local authority has requested you undertake a BS4142 Noise Assessment please call us now on: 01525 303905 or email us at email@example.com.
