Chris Ruane – 2014 Parliamentary Question to the Department for Transport

The below Parliamentary question was asked by Chris Ruane on 2015-01-15.

To ask the Secretary of State for Transport, what limits are in place in relation to noise from (a) aircraft and (b) motor vehicles.

Mr Robert Goodwill

Civil aircraft using UK airports are subject to international noise certification standards. These are set by the International Civil Aviation Organisation (ICAO) and applied at the time of manufacture. In addition some airports may have restrictions in place to limit noise, which will be set out in their Noise Action Plans.

The limit in place in relation to noise for modern passenger cars is 74 decibels. For motorcycles it is between 75 and 80 decibels depending on the size of the machine. For large buses and coaches the limit is between 78 and 80 decibels. For small buses and light goods vehicles it is between 76 and 77 decibels and for heavy goods vehicles the limit is between 77 and 80 decibels. These figures are all measured using a microphone fixed 7.5 metres from the line along which the vehicle is travelling.
