Experimental and Numerical Analysis of Acoustic Performance of Thermal Insulating Materials for Trains

In achieving transport sustainability, the importance of the impacts of noise, as well as the control and reduction thereof, cannot be overstated. According to WHO, transportation noise is one of the biggest environmental problems affecting human health, second only to air pollution. The impact of noise is often regarded as an obstacle to the development of the railway industry. In contrast with other pollutants, the control and reduction of noise has been hampered by insufficient knowledge of quantitative methods to evaluate noise impacts. In this context, it is essential to understand the effects of noise on humans and the associated exposure-response relationships. This paper provides an overview of the research on the impacts and perception of railway noise in Asian countries. The relevant findings, publications, developments, and policies related to railway noise are herein summarized, including recently updated exposure-response relationships for railway noise annoyance based on analysis of Korean surveys.
