“…Traffic and other types of road traffic noise have long attracted significant research interest (e.g. Ambrosio et al 2014;Banerjee et al 2014;Bocquier et al 2014;Bueno et al 2014;Dai et al 2014;Kouroussis et al 2014;Li et al 2014;Sygna et al 2014). In Hong Kong, many elevated bridges are built on top of the existing roads to mitigate the traffic congestion.…”

This study addresses the research on the noise and vibration correlation of a bridge movement joint. The aim of this research is to assess the noise induced by the vibration of a bridge movement joint without lane closure during the operation period. There are two methods of developing the correlation between the tyre/joint noise and vibration: (i) Direct Sound and Vibration Measurement Method, (ii) Acoustic-Box-in-Vehicle Method. The first one is the measurements of the vibration change at a bridge movement joint and roadside noise change induced when a control vehicle is passing it (this one requires lane closure). The correlation between the vibration change and roadside noise change is plotted according the measurement data. The second one is the measurements of the structure-borne noise change in an acoustic box installed into the control vehicle and roadside noise change induced. Similarly, the correlation between the structure-borne noise change and roadside noise induced is plotted. It is found that the two correlations are linear and similar to each other, even though the roadside noise is nonlinearly increasing against the control vehicle speed.
