Assessment of railway soundscape in rural areas

Abstract

In the present study, railway soundscape in rural areas was assessed by field measurements. Landscape merics of rural areas were analysed, then a total of 10 sites were chosen covering different composition of landscape metrics. Audio-visual recordings were carried out at selected sites; acoustical characteristics of train noises were analyzed in terms of sound quality metrics, ACF (auto correlation function) and IACF (interaural cross correlation function) parameters. It was found that noise levels of high speed trains ranged from around 70 and 90 dBA in terms of Aweighed equivalent noise levels. And it can be seen that IACC values of train noises were dependent on the layout of recorded sites, and perception of train noises were affected by background noise levels.
