Noise Impact Assessments & Environmental Impact Assessments
When any new sources of noise are introduced to the external environment, a report is usually required by the local authority to demonstrate that this will not cause an impact to the existing surroundings. This may be from plant noise such as a new air conditioning unit or entertainment noise such as a new music venue. Particularly in densely populated cities, residential accommodation is always a concern.
British Standard BS4142 Noise Assessments
The standard method for assessing the impact of plant noise is laid out in BS4142 and requires the measurement of the existing noise environment to be carried out over several days, then the proposed sources of noise assessed to demonstrate they will not cause noise levels to increase at nearby sensitive receptors. If it is found that an impact is likely, we work with others to specify acoustic attenuation to mitigate this. Often this will be in the form of louvres, in-line duct attenuation, barriers and acoustic enclosures. We’s also well versed in the requirements of other British Standards such as BS5228, BS 5228 Part 1 and BS8233.
Acoustic Modelling & Noise Impact Assessments
When assessments are more complex, such as several new sources of noise or major changes in the noise environment, a noise mapping model is created which simulates the propagation at noise and allows us to predict the incident noise levels at nearby receptors and facades.
Noise Impact Assessments for Entertainment Venues
The environmental assessment of entertainment noise is laid out in the NPPF however planning policy varies considerably across local authorities. We provide noise impact assessments for a wide range of cases and always ensure the local authority planning policy has been considered.
Breeam Noise Surveys, Building Regulations & Section 61 Consent
In the case of new residential dwellings it’s also required to demonstrate compliance with performance standards such as Building Regulations Approved Document E (ADE), and other schemes such as BREEAM, all of which we can help assist with in providing guidance, testing, assessments and surveys.
