Introducing Plant Noise Surveys
Introducing Plant Noise Surveys
At APT Sound Testing, we understand the growing importance of plant noise surveys, especially when planning authorities require them to ensure compliance with BS4142 standards. If you’ve been asked to conduct a plant noise survey as part of a planning condition, we’re here to help.
Industrial noise is becoming an increasingly critical factor for planning authorities, particularly as the UK government pushes for the redevelopment of brownfield sites. These areas often see industrial and residential developments in close proximity, leading to concerns about noise levels and their impact on local amenity and quality of life. As a result, noise from industrial operations — such as machinery, plant, and equipment — must be carefully assessed and managed to avoid disrupting nearby communities.
Local authorities often impose restrictions on noise emissions, particularly in areas near residential properties, and achieving compliance with sound pressure level limits is essential. These limits can apply either at the site boundary or at sensitive receptors, such as nearby homes. To meet these conditions, it’s crucial to assess current noise levels, set appropriate guidelines, and monitor compliance with noise limits to ensure that noise doesn’t cause harm to local residents.
Our Plant Noise Survey Services
If you’re planning to introduce a new noise source to your site, we will begin by measuring the existing background noise levels over a 24-hour period. This helps us understand the baseline conditions of the area before assessing the potential impact of your new noise source. If the noise source is already present, we’ll measure the noise levels both with and without the source operating to establish the difference.
BS4142 provides the recognised methodology for assessing industrial noise, particularly in areas with residential housing. This standard involves measuring the existing background noise levels, typically using the LA90 measure (the level exceeded for 90% of the time), at different times of day, if necessary. Our consultants are highly experienced in applying the methods and meeting the requirements set out in BS4142, ensuring that your survey complies with the necessary regulations.
Comprehensive Reporting & Mitigation Recommendations
Our team offers detailed survey reports that clearly outline the findings and provide recommendations for noise mitigation measures where necessary. We use noise mapping techniques to demonstrate the practical effectiveness of these measures in real-world conditions. Our assessments can cover a wide range of industrial operations, including air conditioning systems, extraction units, refrigeration equipment, and general industrial plant operations.
We use the latest Norsonic acoustic equipment to conduct our surveys, ensuring accurate and reliable results. Our commitment to using state-of-the-art technology ensures that your noise survey is fully compliant with BS4142 and meets the expectations of your local authority.
If your local authority has requested that you undertake a BS4142 noise assessment, don’t hesitate to get in touch. We can guide you through the process, providing expert advice and delivering a professional noise survey that helps you achieve compliance.
