The structure-borne noise while the vehicle passing across bridge expansion joint is main source of urban noise. In order to control this pollution, 20 bridges including three types typical joints in Ningbo City were selected, and noises measured passed joints. results are expressed by Z-weighted sound pressure level, which kept effect low-frequency Then influence factors discussed. show that: ...
OBJECTIVES The epidemiological evidence for adverse health effects of long-term exposure to air and noise pollution from traffic is not coherent. Further, the relative roles of background versus near traffic pollution concentrations in this process are unclear. We investigated relationships between modelled concentrations of air and noise pollution from traffic and incident cardiorespiratory di...
