HC Deb 18 March 1986 vol 94 c157W
Mr. Gareth Wardell

asked the Secretary of State for Transport what information he has on the noise effects of motor cycles on the rider's hearing.

Mr. Peter Bottomley

This has been the subject of research which suggests that under certain conditions motor cyclists may risk damaging their hearing. I shall send my hon. Friend a copy of a recent paper published by the institution of Mechanical Engineers, which summarises the available information.
