Traffic noise survey of Turin,Italy

This paper describes an objective traffic noise survey of Turin, an industrial town in north Italy. The main objects of the investigation were to determine the nature and level of outdoor traffic noise in an actual urban situation and to verify the relationships between level of traffic noise, traffic volume and traffic composition.Noise measurements were performed at 70 locations uniformly distributed over the town, in the autumn of 1974. A ten-minute record was made at each site every hour for 23 hours.The results are presented and compared with published data from previous surveys carried out in other European and North American towns.
