HC Deb 09 November 1960 vol 629 c43W
44. Mr. Iremonger

asked the Minister of Transport what progress has been made in studying vehicle noise, with a view to standardising tests and producing a suitable noise measuring instrument; and when he expects to be able to introduce regulations prescribing permissible noise levels for vehicles of various classes.

Mr. Marples

It is hoped that the British Standards Institution will complete, within the next few months, specifications for methods of vehicle noise measurement and for noise measuring instruments. When both these specifications are available it should be possible for suitable meters to be produced. I shall then be in a position to propose new regulations.
