The National Planning Policy Framework (NPPF)
Residential Noise Planning Assessments are controlled by The National Planning Policy Framework (NPPF) published by the Department for Communities and Local Government.
Typical sources of noise assessed under this framework include:
- Road and Rail Noise
- Entertainment Noise such as from bars or nightclubs.
- Mechanical Noise such as air conditioning units
- Industrial Noise
In order to regulate the measurement and assessment of the impact of these sources of noise and vibration, a number of documents exist, known as British Standards. These include, but are not limited to the following:
BS4142 : 2014 – Method for rating industrial noise affecting mixed residential and industrial areas.
BS8233 : 2014 – Sound Insulation and Noise Reduction for Buildings – Code of Practice.
The World Health Organisation – Guidelines for Community Noise
The process of undertaking a planning applications noise assessment generally includes the following steps:
- Measure the existing Noise Environment at and around the proposed new development
- Calculation of internal noise levels within the new development based on planning proposal
- Compare the calculated internal noise level with Local Planning Policy and assess compliance
- If necessary, provide Mitigation Advice to demonstrate that Local Planning Policy can be met
