HC Deb 31 July 1957 vol 574 c192W
69. Mr. E. Fletcher

asked the Minister of Transport and Civil Aviation what steps he is taking to regulate the growing nuisance caused, particularly at night, by noisy motor-cycles and other vehicles.

Mr. Nugent

We have arranged, in conjunction with the manufacturers, for the noise level of several types of machine to be measured and compared to see whether improvements can be made in the design of exhaust systems.
