Design approaches to noise abatement for the high-rise residential along the shenzhen main roads

Shenzhen is a fast urbanization city that has been decorated by density high-rise buildings along fast-speed roads. To the peoples inhabited along the Shenzhen main roads, noise problem is rather big which is ranked the first environment problem by local peoples. In this paper, traffic noise problems from three Shenzhen main roads have been investigated. The result shows that three main roads from east to west have serious noise problem with above 75dB noise level. In terms of typical noise impact on the high-rise residential along the roads, various design approaches are proposed to reduce noise impact via studying noise maps around roads' area and surrounding buildings. It is found that three design approaches from site-plan, room layout and balcony design can be used to achieve noise abatement.
