Most Local Authorities request an environmental noise impact assessment report to support planning applications for new residential developments. A suitable assessment will consider guidance set out in the National Planning Policy Framework (NPPF), Noise Policy Statement for England (NPSE), Planning Practice Guidance – Noise (PPG-N), British Standards BS 8233:2014, BS 4142:2014 and BS 6472-1:2008, ProPG: Planning & Noise, and relevant local policies or supplementary guidance documents, as appropriate for the individual development.
The assessment should ensure that noise intrusion to a new residential dwelling will not be disturbing to future occupants; and contributes to achieving sustainable developments that are fit for purpose.
We undertake the necessary noise and vibration surveys, acoustic modelling and calculations, and provide advice to architects, developers, planning consultants, and contractors. Typically this includes acoustic specification for glazing, façade elements, and ventilation schemes. Mitigation schemes could also include changing the orientation of buildings or rooms within the building or external features such as acoustic barriers.
Where a development incorporates mechanical ventilation such as MVHR or fan coil units (FCUs) or there is new external mechanical plant such as air conditioning, there is potential that noise and vibration could disturb occupants of either the new development or other existing properties nearby. ACA Acoustics can assess the impact of the new plant and provide cost-effective and practical solutions to control noise and vibration to acceptable levels.
We are also able to assess noise to ensure compliance with Passivhaus Standards, including from MVHR and air source heat pumps.
As the design progresses we provide advice relating to the sound insulation performance of separating walls and floors between dwellings to ensure compliance with The Building Regulations Approved Document E. During the construction phase we can also undertake site inspections and provide ongoing advice to the contractor and design team. Finally, we can undertake the pre-completion sound insulation tests required for Building Control approval.
We have assisted with projects ranging from large-scale residential developments, high-rise apartment blocks, mixed-use buildings, and high-end residential dwellings, through to single infill houses, and the change-of-use of office or other buildings to residential flats. Please give us a call to discuss how we can help with your next development.
