THE INCREASE AND DECREASE OF TRAFFIC NOISE LEVELS AT INTERSECTIONS MEASURED WITH A MOVING MICROPHONE

A method is given to measure the sound level, the number of motor revolutions and the speed of a vehicle while it is driving on the road. This method leads to very detailed time plots. Measurements were taken for three vehicles: a passenger car, a van and a lorry. From the time plots spatial plots are made giving the sound level increase per road segment at intersections compared with the free flow situation. Increases are found of 6 to 8 db(a) for road segments close to the border line. From an inhomogeneous line source equivalent sound levels were calculated at microphone positions around the intersection. Maximum increases are found of 6 db(a), while 3 to 4 db(a) is a typical value close to the border line. (Author/TRRL)
