An environmental noise assessment ensures that no new developments built in England & Wales will have a detrimental effect on the environment. This includes the health and well being of future residents and wildlife. 
We also cover Scotland and Northern Ireland, although these countries are subject to different guidance for environmental acoustics.

Undertaking an environmental noise survey is a key element to the overall assessment and generally carried out to BS 4142. Depending on the project other guidance may also need to be taken into consideration.
Noise is now understood to be detrimental to the health and well being of those that are subject to excessive or continuous sources and therefore the Government has introduced legislation to ensure that all aspects of a building comply with a set of agreed standards.
Such standards include the Building Regulations, with Approved Document E covering the requirements for the “Resistance to the passage of sound”. 

Environmental noise assessments are not solely required for residential developments.  They may be requested for a wide variety of developments including quarries, industrial estates and infrastructure projects (rail, roads and air travel).

Environmental Acoustics

To ensure new developments comply with acoustic requirements an Environmental Noise Assessment will be requested by the local planning authority.  This will ensure that any pre-existing noise sources, such as high traffic volumes or industrial sites, will not have a negative effect on the proposed site (and dwellings).
Excess noise issues identified can then be mitigated within the design to comply with the planning authority’s requirements. Designs can include suitable facades, internal partitions and other features that are required to meet specification.
By undertaking a process to identify, measure and calculate existing noise levels, we can propose suitable acoustic design and specification requirements for your project.
A final report provides full analysis of the data gathered and recommendation’s for any design or specification to eliminate or mitigate these levels affecting those using the building or space.

Guidance for an environmental noise assessment

Environmental noise assessments are carried out to meet various standards and regulations depending on the application being considered. To meet the performance levels required, based on the final use of the building or space, one or more of these may be applicable, including:
BS 4142:2014+A1:2019 – Methods for rating and assessing industrial and commercial sound
BS 8233:2014 – Offers guidance on sound insulation and noise reduction for buildings
BS 7445:1991 – Details the descriptions and measurements of environmental noise
The National Planning Policy Framework
Local Authority Requirements
Approved Document E for residential developments in England & Wales
Building Standards Technical Handbook 2019: Section 5 Noise (for residential developments) Scotland
Technical Guidance G for residential developments in Northern Ireland

Reporting

Depending on the site and requirements, tests can undertaken over a number of days (usually 1 to 7).
Once the data has been collected we will endeavour to have a completed report to you within 5 working days
