Green ceramsite concrete is an environmentally friendly sound-absorbing material for high-
speed railway sound barriers. However, given its low sound absorption, this material is not …

Abstract Models for predicting railway rolling noise such as TWINS are well-established and
have been validated against field measurements. However, there are still some areas where …

Noise is one of the key issues in the operation of high-speed railways, with sound source
localisation and its transfer path as the two major aspects. This study investigates both the …

Foam glass-ceramics have the characteristics of broadband sound absorption, lightweight
and high-strength, which can be utilized in sound barriers on traffic networks. Due to the …

Compared with traditional finite element analysis and statistical energy analysis, the energy
finite element analysis (EFEA) has the advantages of small computations and solving local …

Conventional railway track is supported by a layer of crushed stones known as ballast. In
recent years concrete slab tracks have been introduced which have been used widely in the …

The research progress on wheel-rail noise prediction models was summarized, the main
modeling methods and their features were elucidated, and some representative results, and …

With the large-scale construction of suburban railway viaducts, the noise problem along the
viaducts is becoming more and more prominent. Conventional vertical noise barriers have …

Rail shields have been developed recently which are fitted around the lower part of the rail
and are intended to reduce the noise radiated by the rail. Their effect on the sound radiation …
