Noise barrier protects birds from loud trains

Sound level reduced to 50 decibels, similar to that of normal conversation

Engineers and technicians working on the Shenzhen-Maoming Railway, an important transport link between the two coastal cities in Guangdong province, have finished construction of a fully enclosed noise barrier on a section running through an ecological scenic site.

The 2,036-meter arched steel structure, with sound insulation and concrete acoustic boards, is just 800 meters from Birds' Paradise, a scenic and ecological attraction in Jiangmen, Guangdong.
