The paper presents various ways of protection from traffic noise used in railway infrastructure in Poland. The sources of noise in rail and tram transport were discussed. Also commonly found solutions on the railway network were analyzed such as noise barriers and rail dampers. Modern tram surfaces have been presented as one of the noise protection methods in the tram infrastructure. In the tram infrastructure a noise protection method was presented in the form of tram track lubricators on sharp curves. In addition, the effectiveness of noise protection methods was assessed on the basis of tests and research.

“…1,2 In recent years, rail dynamic vibration absorber (DVA), as a promising means of suppressing the noise radiated by the rail component, has been researched extensively. In Dumitriu and Cruceanu, 3 the measures to mitigate the rolling noise by using the rail DVAs in many European countries are reviewed. From the point of view of practical implementation, the most available studies have focused on the reduction of the rolling noise.…”

In this study, a rail dynamic vibration absorber with negative stiffness is developed to reduce the vibration transmission and radiated noise from the rail components of a ballasted track. The compound models of the ballasted track system with and without the proposed dynamic vibration absorber and a traditional dynamic vibration absorber are constructed. A parametric study is performed to evaluate the effects of the design parameters of the proposed dynamic vibration absorber on the vibration and noise reduction of the track system in terms of the point receptance, the decay rate of rail vibration along the track, and the vibration energy level of the rail. Compared with the traditional dynamic vibration absorber, the proposed counterpart can work effectively over a broad frequency range around resonance. The efficiency of the dynamic vibration absorber can be improved by adjusting the design values of the active mass and damping coefficient. A comparison with the traditional dynamic vibration absorber shows that the vibration and noise suppression capability of the proposed one can be enhanced by increasing the value of the stiffness ratio. However, different from the traditional dynamic vibration absorber, the design parameters of the proposed one can also affect the decay rate and vibration energy at low-frequency regions. A discrete track with the proposed dynamic vibration absorber, which is arranged in continuous or discrete distribution along the rail, is illustrated to study the influences of the rail components on the decay rate and vibration energy level of rails. These calculated results could provide a theoretical basis for the design of the proposed dynamic vibration absorber in controlling the vibration and radiated noise from rails.

Abstract. Rail dampers are mechanical devices mounted at both sides of the rail web aiming to reduce the vibration along the rail. In this way, a shorter length of the rail vibrates effectively and the rolling noise is less intense. In this paper, a continuous model consisting in an infinite Timoshenko beam on multi-elastic layers is adopted for the railway track with rail dampers. The equations of motion are solved using the Green's function method and the frequency-response of UIC 49 rail is derived and analysed in terms of the receptance and decay rate of vibration depending on the possible dimensions of the rail dampers.
