Transportation Noise | BS 8233

Transportation noise assessments

Road, rail and air traffic are the most common transportation noise sources in society.  For noise sensitive developments, including new houses or flats, an assessment can be required. These identify the risks and impacts, and secure measures to protect people from adverse effects of noise.

Policies and guidance

When assessing the impact of transportation sources on noise-sensitive buildings, we can refer to the following:

  • ProPG: Planning & Noise – New Residential Development
  • National Planning Policy Framework (NPPF)  (as replacing Planning Policy Guidance 24: Planning and Noise [PPG24]).
  • BS 8233:2014 Guidance on sound insulation and noise reduction for buildings.
  • The World Health Organisation Guidelines for Community Noise (1999).
  • Calculation of Road Traffic Noise (CRTN, 1998).
  • Calculation of Railway Noise (CRN, 1995).

Our assessment approach

If you are going through the planning process you may require an assessment. At SSC, we always determine local policy requirements before starting out. This is because, noise policies often differ between Local Authorities. By understanding all the requirements from the outset, our report can be tailored to suit local requirements.

To reduce uncertainty in our proposals, we normally consider full day and night-time readings. As a basis for any predictions, we use leading manufacturers’ test data for windows and ventilators.

Mitigation measures

We aim to provide mitigation advice that is simple to employ and cost effective for the end user. Following the principles of noise control, we reduce noise in the following hierarchy:

  • At source.
  • Along the transmission path.
  • At the receptor.

Our reports are always clearly detailed. Providing policy requirements, raw data, calculations and mitigation (where appropriate). As well as the proving the consultants’ relevant industry experience.

Pre-occupation internal ambient noise level testing

Councils sometimes request internal ambient noise level tests (IANL) prior to occupation. Often, to demonstrate transportation noise levels comply with suitable health criteria.  However, such testing is not normally carried out on all residential developments.

At SSC we will assist in agreeing a testing schedule and method with the relevant authority prior to starting. Unless otherwise provided in writing.

Road traffic impacts caused by development

Road traffic noise impacts are normally considered for developments of a larger scale. Amongst other guidance, we use the Calculation of Road Traffic Noise (CRTN, 1998).  There are various aspects to consider in reviewing road traffic noise impacts. One of these, is the difference in traffic flow caused by the new development.

Noise modelling

We can provide noise modelling services for proposed developments. These models are formed in accordance with industry standard methods.
