HC Deb 01 February 1961 vol 633 c122W
44. Mr. Iremonger

asked the Minister of Transport whether he is yet in a position to propose regulations prescribing permissible noise levels for vehicles of various classes.

Mr. Hay:

No. The British Standard on methods of measuring vehicle noise is however now in draft, and the results of tests undertaken to establish both the noise made by existing vehicles and the effect of certain sound levels on bystanders are being analysed.
