Noise evaluation of developed egg shaped sound-proofing wall for high speed railway by field test

摘要

Considering speed increase in the future, noise prevention is a major issue for railway enterprises. In general, railway enterprises build higher sound proofing walls as a countermeasure to increased noise. In this paper we propose a method to derive noise absorbing material and noise absorbing device, we measure noise evaluation of viaduct for high speed railway by field test.
