Railway Noise Impact on Residents Living in Small Towns — In case of Gomen-Nahari Line, Kochi Prefecture —

摘要

In present study, noise from Gomen-Nahari railway of Kochi Prefecture was investigated. Field measurements data and social survey data indicated that, although the railway noise levels are less than the standard value of 10 dB(A), about half of respondents reported annoyed. Furthermore, the frequency spectrum of this noise source possesses a prominent peak in the range of 400-3000 Hz, which is the frequency range that easily makes people feel annoyance. This study suggested that in small towns, whenland use planning is made, from viewpoint of noise, it should not simply refer to the noise level standard; background sound level and noise source characteristic also should be considered.
