Noise barriers are regarded as the most efficient way to mitigate high-speed railway (HSR)
noise. To enhance their performance, the present paper introduces a novel type of noise …

The localization of linearly moving sound sources using microphone arrays is particularly
challenging as the transient nature of the signal leads to relatively short observation periods …

With the aim of studying the noise reduction performance of the vertical noise barrier on
railway bridges, this paper introduces the statistical energy analysis (SEA) to predict their …

Localizing linearly moving sound sources using microphone arrays is particularly
challenging as the transient nature of the signal leads to relatively short observation periods …

A geometrical formula which includes the effect of first order reflections, diffraction, and a
diffuse reverberant field is presented to predict the acoustic insertion loss of rectangular …

The Burton-Miller method is a widely used approach in acoustics to enhance the stability of
the boundary element method for exterior Helmholtz problems at so-called critical …

Benchmark cases in the field of computational physics, on the one hand, have to contain a
certain complexity to test numerical edge cases and, on the other hand, require the …

The effect of railway platforms on sound propagation has thus far not been investigated in
detail. Due to the vicinity to the track, the platform's large reflecting horizontal surface, and …

In a translation-invariant environment, the three-dimensional sound field can be determined
through spatial Fourier transform by superimposing two-dimensional sound fields. This …

The boundary element method in 2.5 D allows for the usage of moving sources by a
modification in the wave number frequency domain. The 2.5 D boundary element method …
