Noise Effects and Management

The factors and sources of noise are constantly investigated, as well as the methods of reduction that can help prevent noise pollution. According to ISO 1996-2 taking into account the position of the noise measurement, distance, meteorological and environmental conditions. The aim of the work is to evaluate the dependence and the propagation of noise in the environment caused by train traffic, which depends on different types of sleepers. The results showed that the stretch with wooden sleepers was "quieter" at 3 dB than the section with concrete sleepers, in the sections were measurements was taken: Senieji Trakai-Rudiskes (section with concrete sleepers) and Rudiskes-Matuizos (section with wooden sleepers). The measurements carried out throughout the study showed that the fixed passage noise of the trains falls into the low frequency noise level (31.5–400 Hz).
