HC Deb 20 March 1969 vol 780 c128W
16. Dr. Winstanley

asked the Secretary of State for the Home Department what arrangements are being made to fit police Panda patrol cars with acoustic apparatus to enable the occupant to hear sounds such as burglar alarms, shots, calls for help, and police whistles which would normally be heard by a police constable on foot patrol.

Mr. Elystan Morgan

The police do not consider such equipment to be necessary.
