TL;DR: In this article, the quantification of aero-acoustic and rolling noise sources emitted by high-speed trains externally is discussed, based on the comparison of experimental data obtained in the DEUFRAKO Annex K and K2 projects and those produced more recently.

TL;DR: In this article, a study on the perception of soundscapes in train stations is presented, which shows that people's knowledge about the space typology that makes up a train station is also based on sound information, and this information is involved in the recognition of the type of space.

TL;DR: In this paper, the authors defined a Gaussian half-width, where the Gaussian halfwidth is defined as the ratio of specific heats to the free field, and the free-field pressure level relative to the noise level is defined.
Abstract: B = Gaussian half-width, m c0 = speed of sound, m=s dL = porous layer thickness, m f = frequency, Hz Im = imaginary part j = imaginary unit k = complex wave number, m 1 p = pressure, Pa q = tortuosity Re = real part S = number of first-order systems in the impedance approximation sf = coefficient of the selective filter T = number of second-order systems in the impedance approximation t = time, s v = velocity component normal to impedance surface, m=s Z = complex impedance, kg=m=s = ratio of specific heats L = sound pressure level relative to the free field, dB t = time step, s x = spatial mesh size, m 0 = air density, kg=m 0, e = flow resistivity, Pa s=m = porosity ! = angular frequency, rad=s

TL;DR: For the past 15 years, a number of tests at high speed were carried out for different trains in different countries (France, Germany, Italy, Japan, Spain, Spain ...).
Abstract: For the past 15 years, a number of tests at high speed were carried out for different trains in different countries (France, Germany, Italy, Japan, Spain ) In the TGV case, apart from test at operating commercial speeds, various acoustical measurements were carried out, either within dedicated programs (Deufrako Cooperations K and K2, 350 kph measurement campaign a few years ago on TGV Duplex, and more recently 360 kph test on TGV Reseau), or at the occasions of very high speed campaigns

TL;DR: In this article, the vibroacoustic study of a reference steel bridge has been carried out over the whole frequency range from 5 to 5000 Hz using the finite element method (FEM) in the low-frequency range and statistical energy analysis (SEA) at higher frequencies.

TL;DR: An account of the state of the art in acoustic scene classification (ASC), the task of classifying environments from the sounds they produce, and a range of different algorithms submitted for a data challenge to provide a general and fair benchmark for ASC techniques.
Abstract: In this article, we present an account of the state of the art in acoustic scene classification (ASC), the task of classifying environments from the sounds they produce. Starting from a historical review of previous research in this area, we define a general framework for ASC and present different implementations of its components. We then describe a range of different algorithms submitted for a data challenge that was held to provide a general and fair benchmark for ASC techniques. The data set recorded for this purpose is presented along with the performance metrics that are used to evaluate the algorithms and statistical significance tests to compare the submitted methods.

TL;DR: In this article, a Principal Component Analysis (PCA) was conducted to decompose descriptors of the urban soundscape into two independent emotional dimensions, i.e., calmness and vibrancy.
181 citations
TL;DR: The results show the limitations of traditional noise mapping for railway epidemiological studies based exclusively on ordinary transits and confirm the role of vibrations as enhancing factor for disturbance.
