Study on the correlation between noise perception and annoyance level of residents living near the railway

In recent years, the rapid development of railway transportation in China has resulted a complex acoustic environment in residential areas near railway, where noise and vibration from train operation have an impact on human health. Therefore, in this study, a questionnaire survey was conducted on the acoustic environment of residential areas near railway using subjective evaluation, and the correlation between residents' noise notice and annoyance levels was investigated. The results show that there is a significant correlation between railway noise notice and annoyance levels (p<0.01). Railway vibration did not cause annoyance, but the combined effect of railway vibration and railway noise increased annoyance levels (p<0.01). In terms of noise notice, there is a railway bonus for residents during the day. In addition, there are differences between men and women in terms of noise notice and annoyance levels during the day and night. The living floor factor had a significant effect on railway noise notice, but not on railway noise-induced annoyance. The results of the study may provide guidance for setting noise limits for railway operations at different times of day.
