5.0m³/s £2,200 £210 £250 £1,050 £550<br />
Note: All <strong>the</strong> above costs are based <strong>on</strong> a fan running at a noise rating <strong>of</strong> NR60 with an<br />
anticipated maintained space noise rating <strong>of</strong> NR40.<br />
4.10.4 Relative cost effectiveness <strong>of</strong> odour abatement systems<br />
Table 4.16 compares <strong>the</strong> anticipated level <strong>of</strong> noise c<strong>on</strong>trol against <strong>the</strong> estimated cost<br />
for installing <strong>and</strong> maintaining a system.<br />
