World Health Organisation Guidelines<br />
<strong>The</strong> guideline values for community noise published by the World Health<br />
Organisation (WHO) cover a wide range of issues, extending beyond<br />
‘ambient noise’. <strong>The</strong> guidelines follow a precautionary approach, and may<br />
be taken in general terms as levels below which adverse effects would not<br />
be expected.<br />

Planning Policy Guidance<br />
Government planning guidance relevant to noise, issued by departments<br />
now within the Office of the Deputy Prime Minister (www.odpm.gov.uk),<br />
available from <strong>The</strong> Stationery Office, is referred to below. <strong>The</strong><br />
Government is reviewing national policy guidance. This includes replacing<br />
planning policy guidance notes (PPGs) with national planning policy<br />
statements (PPSs).<br />
Planning Policy Guidance Note 24 (PPG24) ‘Planning and <strong>Noise</strong>’<br />
September 1994<br />
PPG24 provides advice to local authorities on ‘how the planning system<br />
can be used to minimise the adverse impact of noise without placing<br />
unreasonable restrictions on development or adding unduly to the costs<br />
and administrative burdens of business’ (paragraph 1). Guidance refers to<br />
‘proportionate and reasonable’ measures to control the source of noise or<br />
to limit exposure to it, such measures including:<br />
■<br />
■<br />
■<br />
engineering - e.g. using quieter machinery, containing or screening<br />
sources, or receptors;<br />
layout - e.g. distance, screening by other buildings, or non-critical<br />
rooms in a building;<br />
administrative - e.g. limiting source operating time, restricting<br />
activities on the site, specifying an acceptable noise limit.<br />
PPG24 introduced the concept of <strong>Noise</strong> Exposure Categories (NEC), A to<br />
D, which local planning authorities should use when assessing proposals<br />
for residential development affected by road, rail, air traffic or mixed<br />
sources. Table 14 lists the noise levels used to classify different sites.<br />

granting planning permission, although the noise level at the high end
