Autor: Zvolenský Peter, Grenčík Juraj, Kašiar Ľubomír, Stuchlý Vladimír

Publikováno v: MATEC Web of Conferences, Vol 157, p 02058 (2018)

Currently, the quality of structural design of a railway coach is evaluated by so called acoustic comfort, which is characterized by achieved levels of internal noise. Therefore, acoustic parameters of car body are being developed purposely. The pape

Analysis of the efficiency of low noise barrier using STERED material

Autor: Zvolenský Peter, Pultznerová Alžbeta, Grenčík Juraj

Publikováno v: MATEC Web of Conferences, Vol 196, p 04076 (2018)

When reducing noise, especially around the so-called corridor railway tracks, but also at the hump yard, the most suitable structure and composition of acoustic barrier materials are searched. It is also issue of the durability and stability paramete

Research of noise emission sources in railway transport and effective ways of their reduction

Autor: Zvolenský Peter, Grenčík Juraj, Pultznerová Alžbeta, Kašiar Ľubomír

Publikováno v: MATEC Web of Conferences, Vol 107, p 00073 (2017)

In the EU conditions attention is systematically paid to noise reduction on the railways. Because TSI rules systematically tighten limits for noise emissions from railway vehicles, noise research must be addressed by all Member States, as the main te

The simulation calculation of acoustics energy transfer through the material structure

Autor: Zvolenský Peter, Pultznerová Alžbeta, Grenčík Juraj

Publikováno v: MATEC Web of Conferences, Vol 86, p 04001 (2016)

The paper deals with the modification of the rail passenger coach floor design aimed at improvement of sound reduction index. Refurbishing was performed by using a new acoustic material with a filamentary microstructure. The materials proposed in res
