Environmental Noise Assessments ensure that no new developments built in England & Wales (Scotland and Northern Ireland have different standards) will have a detrimental effect on the environment (including wildlife) and on the health and well being of future residents. 
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 Approved Documents with Approved Document E referring directly 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).

What do we test and why?
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).
Architects and planners can mitigate any excess noise issues identified and comply with the planning authority’s requirements. Designs can include suitable facades, internal partitions and other features that are required to meet specification.
Any proposals and concerns that stake holders may have are included in the final report and designs.

What are we testing to?
Environmental noise assessments are carried out to meet various standards and regulations. Depending on the site or area 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 (Environmental Impact Assessment) 
Local Authority Requirements
Approved Document E (for residential developments) England & Wales
Building Standards Technical Handbook 2019: Section 5 Noise (for residential developments) Scotland
Technical Guidance G (for residential developments) Northern Ireland
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
