departments. Recent complaints statistics are shown in Figure 3. <strong>The</strong>re are<br />

several reasons why such service-related data cannot be regarded as a simple<br />

reflection of noise itself (see notes to Figure 3). About 70 per cent of all<br />

complaints are about domestic noise. <strong>The</strong> overall number of complaints<br />

appears to have levelled off. Complaints about construction/demolition noise<br />

appear to have become a larger proportion in <strong>London</strong> in recent years.<br />

<strong>London</strong> related data from<br />

the 2000 National <strong>Noise</strong><br />

Attitude Survey<br />

2.21 During 1999/2000, a National <strong>Noise</strong> Attitude Survey, carried out by the<br />

Building Research Establishment (BRE) for the then Department of the<br />

Environment, Transport and the Regions, included a sample of 350 home<br />

interviews in <strong>Greater</strong> <strong>London</strong>. <strong>The</strong> survey was designed as a national one,<br />

and cannot be taken as fully representative of <strong>London</strong>. <strong>The</strong> areas picked<br />

up in sampling were in parts of North and South Outer <strong>London</strong> (see map<br />

in margin). If the survey had been designed specifically to be analysed at<br />

the <strong>Greater</strong> <strong>London</strong> level, a different sampling strategy would have been<br />

used, with a better geographical spread of interviews over the whole city.<br />

Box 10: NSCA National <strong>Noise</strong> Survey 2002<br />

Aiming to overcome differences in the way complaints data are collected,<br />

the NSCA (National Society for Clean Air and Environmental Protection)<br />

surveys Chief Environmental Health Officers. <strong>The</strong>y are asked what they<br />

consider to be the major sources of complaint about noise nuisance in their<br />

authority’s areas. In 2002, 17 <strong>London</strong> boroughs (51 per cent) responded.
