Simulation Study on Traffic Noise Reduction in Residential Garden with Open Ground Floor Closing to the Road—— A Case Study on Guangzhou New World Oriental Residential Area
In this paper,a simulation research on traffic noise reduction in Guangzhou New World Oriental residential area was presented , including absorption design on open floor's interior-face , optimization on solid enclosure height, and improving design for fire-gateway. The results shown that the absorption design on open floor's ceiling and wall could make the noise reduced up to 2. 2 dBA. Furthermore,two-meter-high solid enclosure could make the noise reduced about 1. 8 dBA,and could up to 4. 4 dBA when combining with the absorption design on the ceiling and wall of open floor. In addition, physical methods for fire-gateway's noise reduction were not effective,most of them couldn't make the noise reduced over 0. 7 dBA.
