An environmental noise assessment is a detailed noise survey and is often required for planning applications and are requested by local authorities in order to establish the environmental noise impacts of a development. An environmental noise assessment will typically involve an assessment of the existing noise environment and comparison of the predicted of the noise level generated by the proposed development. Noise impact assessments/ noise surveys/ noise tests are normally requested by a Planning Officer or by the Local Authority due to concerns relating to construction of new residential dwellings (or change of use) in a high noise exposure area. New dwellings can be exposed to road traffic, rail, air or mechanical/commercial noise which is unacceptable.
Environmental Noise Survey
In the case of proposed housing development the impact of existing noise sources will need to be assessed to ensure that an acceptable internal and external dwelling environment can be created without unreasonable burdens being placed on other nearby noise generators. A noise impact assessment might also be taken in order to measure the status quo. Sometimes industry is required to keep a check on the level of noise they emit to ensure compliance with any imposed noise conditions and / or to demonstrate good neighbourliness.
Many residential or mixed use developments require a noise assessment to support the planning application. This ensures that adequate protection is provided for future residents by minimising noise impacts. Advice is provided in Planning Policy Guidance, however, this has recently been replaced by the National Planning Policy Framework (NPPF), although some Local Authorities still use the guidance within or based on BS8233 noise assessment and BS4142 assessment and local authority noise policies.
If you require an environmental noise assessment to support your planning application, we can offer bespoke solutions to best meet your needs.
AF Acoustics and the local authority will liaise together in order to provide specific guidance on the assessment of noise on sites proposed for residential development.
AF Acoustics can guide you through the activities required to discharge any planning conditions which for residential development normally require demonstrating compliance with noise limits or mitigation measures including acoustical performance specifications for building elements including glazing.
Once planning permission has been gained for a scheme or project, it is common for noise related planning conditions to be attached which require discharge prior to works commencing on-site.
Most noise impact assessments include outline recommendations for glazing and ventilation to meet internal noise, guided by BS8233 and/or World Health Organisation guidelines and to meet the planning conditions.
