천안시청 주변의 소음 평가 및 소음지도 작성

Abstract

Noise pollution problem has been occurred by the increase of traffic flow and population in many cities. Noise in cities is a common issue which has been studied extensively around the world. Urban noise is especially considered as a public health problem. The purpose of this study is to evaluate environmental noise on stretches of road in Cheonan city hall and its vicinity, based on in-situ measurements and the calculation of noise maps. To characterize noise in the evaluated road stretches, 6 measurements were taken at different points. The CadnaA software was used for the noise mapping calculations. As a result, a large part of an apartment community around the main road indicated noise levels exceeding the legal limits during nighttime. Various methods to reduce the noise level were provided through the simulation using the noise mapping.
