Planning Noise Surveys (PPG24)
Industrial Planning Noise Surveys (PPG24)
We have considerable experience and skill in dealing with PPG24
Noise Assessments and PPG24
Noise surveys for the planning applications for both small and large
developments. More often than not its in relation to new build apartments,
houses, or hotels, if you are unsure how to achieve compliance for your
planning application phone APT now, or e-mail us at info@airpressuretesting.net
for a quick proactive response.
Noise assessments are often required at the Planning stage of developments
that may generate noise, and noise-sensitive developments which may be
affected by noise. Some developments, such as mixed use, fall into both
categories. Potentially noise generating developments often require a
Noise Impact Assessment to be undertaken. This normally requires existing
ambient noise levels to be established, typically by undertaking measurements,
and the impact of noise from the development to be established. For large
developments, it is often necessary to consider secondary effects, such
as the impact of increased traffic on existing roads.
We undertake detailed noise modeling in order to calculate anticipated
noise levels from the development. The noise model can also be used to
assess the efficacy of various noise control options.
Noise can also be a Planning issue when noise-sensitive development is
proposed in areas that are subject to high noise levels, or are likely
to be subject to high noise levels in the future. Current UK government
guidance encourages the re-use of brownfield sites and these are often
subject to higher noise levels than greenfield sites.
In the UK, Planning and Noise is currently guided by PPG 24, which defines
four Noise Exposure Categories (NECs), based on the level of noise at
the development. The NEC in which the site falls determines to what extent
noise should be considered in the granting of planning permission.
The NEC(s) for a development are usually determined by monitoring noise
levels. Potential mitigation options can then be assessed by calculation,
and/or the use of noise modeling. Appropriate noise mitigation can then
be incorporated into the development at the design stage.
Internal noise levels within the proposed buildings can be calculated
using our latest noise prediction software. For most buildings, the overall
sound insulation performance of the building envelope will depend on the
glazing system employed. It may be necessary to stipulate specific glazing
and ventilation systems that must be employed to ensure that internal
noise criteria are achieved. Most new residential development, once constructed,
must have Sound Insulation testing undertaken in accordance with Approved
Document E of the Building Regulations.
The area of planning and noise is awash with often contradictory guidance,
standards, codes of practice, and it is unusual that any one of these
documents precisely covers all aspects of a case. PPG24 requires a noise
survey to be conducted at the planning stage to assess the overall suitability
of the site's noise climate for residential development. With it comes
the possibility of noise control measures being necessary as part of the
planning conditions.
Very often there are strong conflicts of opinion between interested parties.
We pride ourselves on being able to deal with the issues in a direct and
simple manner. Problems relating to noise during the planning stages can
usually be avoided or resolved with a good, detailed and accurate acoustic
assessment report. As standard all our reports include highly sophisticated
noise mapping to accurately detail the spread of noise in the surrounding
area for any particular situation. Using the latest acoustic modelling
software we can create the situation and then visually model the results
of many various mitigation measures.
We undertake accurate on-site noise assessments to suit the needs of a
client’s problem and their pocket, and deliver concise and clear
reports in a timescale which is again designed to suit the client.
