Analysis of the impact of the urban traffic noise on the vertical distribution of high-rise residential buildings

Abstract

With the rapid growth of China’s urban population, the construction of its urban transportation network will be more vigorous than ever. The influence of road traffic noise on urban residential areas has become increasingly prominent. However, most of the current research is limited to the analysis of the flat sound field, leaving the research on high-rise residential vertical sound not so detailed. This study aims to find out the vertical sound field distribution law of traffic noise to high-rise buildings on the sides of the road. We monitored the environmental traffic noise effects in a high-rise residential area in Zhejiang Province and established a high-rise residential model in the SoundPLAN Software to simulate the vertical sound field distribution of traffic noise. The law is that the value rises sharply to the peak in the range of 0-7F (23.0m) then decreases slowly as the height increases. We also made a linear analysis of the noise data to arrive at a linear regression equation. This study provides a new way of taking noise prevention and control into consideration in high-rise housing. Special attention must be given to the isolation of traffic noise on floors by selecting soundproof doors and well-functioning windows. This strategy of creating a high-quality sound environment in a residential area can be put forward to improve people’s lifestyle and environment.
