Peculiarities and results of transport noise monitoring with the example of the Samara region of Russia

Problems of transport noise monitoring are considered. Existing approaches to transport noise monitoring have a number of disadvantages. The influence of the noise from transport and other sources on the public health was estimated. The results show a reliable, statistically significant dependence of the population illness growth on acoustical pollution. A new system of transport noise monitoring is suggested and approved in conditions of the Samara region of Russia. This system has a number of advantages for acoustic research. The acoustic characteristics of separate vehicles and their spectral values were investigated as well. Analysis of our measurement results of the transport noise from cars of different kinds shows that the most significant noise values are observed within a low frequency range. Thus, when reducing transport noise down to appropriate hygienic values, special attention should be paid to reduction of the low-frequency component of noise.
