HC Deb 02 March 1994 vol 238 cc734-5W
Mr. Higgins

To ask the Secretary of State for the Home Department over what distance he estimates police sirens can be heard; and if he will introduce a lower volume option so that noise pollution particularly in built up areas and at night is reduced.

Mr. Charles Wardle

The distance over which a police siren can be heard is subject to a number of factors, including the time of day, air temperature and location. Most vehicles are fitted with a control for the siren to enable its volume to be reduced if circumstances permit.
