An Application to Railway Noise Reduction of EPS Sound Absorptive Board

Atsushi Tabata, Nobuaki Kobayashi, Koichi Nagase, Hiroshi Kubota and Tatsuo Mioke

The sound absorptive barrier made of exhausted expanded polystyrene (EPS) was developed for the reduction of railroad noise.
The sound absorptive barrier we developed is two types. One is the "sound barrier type" with sound insulation board inside, and the other is the "hanging type" which is hung to the concrete handrail. The sound absorptive wall of "hanging type" was constructed at Odakyu Electric Railway Kitami train base entrance and exit line.
