NOISE CHECK OF HEAVY VEHICLES IN USE. RESULTS OF MEASUREMENTS AND ASSESSMENTS

STOYKONTROL AV TUNGE KJORETOY I BROK. MALERESULTATER OG VURDERINGER

Noise measurements of 133 heavy vehicles in use was carried out, according to different stationary measuring methods. 6% of the vehicles had obvious defects in the exhaust system, and 4% had levels over 100 db(a), measured 0.5m from the exhaust pipe, without apparent defects in the exhaust system. Against a background of increased noise level due to deficient maintenance, a possible reduction in the equivalent level for road traffic noise is estimated if a noise check of heavy vehicles in use is introduced. Noise and smoke emission were measured for 24 lorries. The report recommends measuring methods for stationary noise checks of vehicles in use.
