§ Mr. Summerson
asked the Secretary of State for the Environment what is the typical decibel level of hooters on fire engines and ambulances; and what assessment his Department has made as to whether they can be made less noisy while remaining effective in clearing the road.
§ Mr. Peter Bottomley
I have been asked to reply.
About 115 decibels at 2m. Chief fire officers and chief ambulance officers decide what type of signal best suits their operational needs. The Department has made no assessment of the kind described.
