Investigation of Noise Generated by Railway Freight Wagon Bogie Type Y25Ls(s)e-K and Proposals of Noise Reduction

Abstract: There have been numerous attempts and investigations carried out with the objective to reduce the noise generated by railway freight wagons because noise is one of ever-present negative environmental pollution phenomena. This resulted in strong legislation requirements on noise reduction in railway transport, in the case of freight wagons, only exterior noise is a problem. However, the extremely hard metal structures of the wagons running on hard rails naturally generate high magnitudes of acoustic energy. One… Show more

“…At the same time, the issue of noise in railway vehicles concerns, on the one hand, the optimization of passengers' sonic experience and, on the other hand, harmonization with industry-imposed quality and health standards. Research on acoustic comfort in railway vehicles [83][84][85][86][87][88][89][90][91][92] has been conducted through an ingenious approach that involves a synergistic combination of advanced technologies and cutting-edge engineering innovations. This process entails the meticulous use of high-performance sound-absorbing materials [84][85][86][87][88][89][90][91][92], adapted to minimize external sound interference, in addition to the integration of noise attenuation systems at the source [93][94][95][96][97][98].…”
