§ Mr. Robert Atkins
asked the Minister of Transport what is the decibel level of motor cycle exhaust noise which is considered acceptable by his Department.
§ Mr. Kenneth Clarke
Statutory limits on noise from motor cycles have existed since 1970, and we propose to introduce stricter limits for new motor cycles in accordance with an EEC directive—78/1015/EEC—adopted last year. The new limits will be:
Engine capacity in cubic capacity and maximum permitted noise level in dB(A) Up to 80 … … 78 Over 80 and up to 125 … … 80 Over 125 and up to 350 … … 83 Over 350 and up to 500 … … 85 Over 500 … … 86
When allowance is made for changes in test procedure, these limits represent a significant improvement over those currently applying.
