NOISE REDUCTION OF A 125 CM3 CROSS MOTORCYCLE

REDUKTION AF STOEJ FRA 125 CM3 MOTO-CROSS MOTORCYKEL

This paper describes how the noise from a 125 cm3 motorcycle can be reduced by using dampers, preventing vibration, insulating the engine etc. Measurements were made according to the so-called selective wrapping method. Results show that the noise was reduced by 5-8 db. (TRRL) abstract of the conference see IRRD 272555.
