BS8233 Noise Assessment

BS8233 Noise Assessment

A BS8233 noise assessment report should be submitted during pre-application discussions or more commonly during a planning application. In some circumstances, a planning condition will be included on the planning permission requiring the submission of a noise report.

In many cases a planning permission officer or the local environmental health team will be the first person involved in informing a client that they are in need of a noise impact assessment, this will typically be due to the fact that a complaint or concern has arisen around the increased noise and/or the perceived increase in noise due to a change of use or an increase in licencing hours.

Our BS8233 noise impact assessment will measure and predict the effects that the new/proposed noise source will be likely have on the current noise climate. This is achieved by firstly establishing a baseline measure of the existing noise climate and then comparing this with the introduced noise. If this comparison cannot be achieved due to practical purposes, then a reasonable prediction can be made through various modelling methods.

There can be a large variety of scenarios and requirements that may be present during noise impact assessments, with this in mind it is important to liaise with the case officer and environmental health team, in order to ensure that the appropriate legislation and British Standards are being adhered to at all times.

If part of your planning conditions requires you undertake a noise survey and would like to speak with one of our noise consultants, then please give us a call us today. The noise assessment process isn’t intrusive, lengthy or costly. Normally we would leave a meter over a 24 hour period which would gather the necessary data automatically, taking into account other factors such as construction, setting and external variables. We could then provide a detailed report and advise how best to proceed.

BS8233 Noise Surveys

BS8233 Noise Surveys  

In large cities, there is far more noise pollution than ever before; this comes from a huge range of noise sources such as traffic, alarms and music/sport venues. As cities populations get larger, people start to inhabit an increasingly compacted space the work of acoustic consultants is becoming ever more important to help reduce excess noise levels. This can be done through a variety of means and methods, one of the most important methods in the context of busy urban environments in the noise impact assessment.

The main purpose of a BS8233 noise assessment is to measure and predict the impact that a development will have on the surrounding environment, residents and whatever noise sensitive receptors happen to be within the vicinity of the development.

The local authority may require a noise impact assessment for a number of reasons, this can include the opening of an entertainment premises in a sensitive area, the installation of new mechanical plant such as a new air-conditioning unit or a change in opening hours of a premises that already has permission to operate from the local council, such as a bar/nightclub wanting to extend its licence from 23.00 to 02.00.

A noise impact assessment may be required at the application stage or once planning permission has been granted. A noise survey and report are required if:

  • The proposed development with commercial areas that may create noise which may affect nearby noise sensitive properties. For example, a new commercial activity near existing residential properties.
  • The proposed development location will be sensitive to noise and is likely to be affected by existing noise sources i.e. busy roads, railway, airports or commercial activity.

=The noise impact assessment is to demonstrate that:

  • The source of noise is evaluated and quantified
  • Nearby noise sensitive receptors identified
  • Noise receptors have been determined with reference to noise standards

The BS8233 noise assessment may also set out control measures where it is necessary to reduce noise to acceptable levels. For example, the installation of different glazing e.g. from double to triple glazed panels or acoustic trickle vents are installed so that internal noise standards are met.

If noise levels are shown as NEC category B and above, the local authority will look for noise reduction measures that will achieve the “good” internal noise level criteria in bedrooms and living rooms set out in BS8233:2014.  Where the noise levels are shown as NEC category D, the local authority usually recommends that planning consent be refused.
