Abstract
Recently, complaints of the excessive railway noise have increased from residents living in high-rise buildings facing railway tracks, both for tracks at grade and on elevated viaducts. Therefore, it is more important than before to predict railway noise at high places and develop countermeasures to reduce the noise. However noise reduction at high places with conventional noise barrier is difficult. In this paper, the effect of noise barriers constructed adjacent to rail on the noise is investigated. Through acoustic tests by using scale models, it is found that, by the noise barriers, the noise at high place is reduced effectively.
