✦ Synopsis

A BSTRA CT The environmental noise level due to motor vehicle traffic to a first approximation is a function of traffic volume. The values of sound pressure level ( L A l ov ) resulting from traffic noise measurements over one-hour periods have been correlated with the equivalent measured numbers of heavy~light vehicles per hour (traffic density). A statistical analysis of the data has been made to enable

LAIOr tO be expressed in terms of the traffic densi O' in the city of Visakhapamam, India in 1986 and1987. Plots of LAlov against logarithm N h (equivalent heavy vehicle density) and logarithm N 1 (equivalent light vehicle densio') fbr the different zones, as well as for the entire city. have been made. The validity of these equations is tested by computing the values of the noise indices from these equations, using the traffic density data and comparing them with the measured values. The difference between the measured and calculated values is very small.
