Influencing mechanisms of multi-dimensional perceptions due to noise inside buildings along metro lines
With the rapid development of urban railway systems,indoor people's complaints about the noise generated by metro operation also increased.In order to control the negative impacts of indoor metro noise on people,it is necessary to evaluate the multi-dimensional negative emotions due to metro noise.In this study,79 participants were exposed to a series of metro noise samples before being asked to cast their multi-dimensional negative perception(depression,discomfort and dissatisfaction)votes.Based on this,this study analyzed the mechanisms of subjective and objective influencing factors on the multi-dimensional negative perceptions due to metro noise using partial least squares(PLS)models,and compared the differences of multi-dimensional negative perceptions in reflecting the impacts of metro noise.The results showed that the multi-dimensional negative perceptions were mainly determined by subjective loudness and acoustic parameters,the influences of activity disturbance,metro noise sensitivity,stance and adaptability were significantly weaker;In addition,among the three multi-dimensional negative perceptions,compared to depression,discomfort and dissatisfaction were slightly more significantly affected by subjective loudness,and under the same subjective loudness perceptions,the levels of dissatisfaction were the highest.The results could provide references for evaluating and improving the negative perceptions due to noise in buildings along metro lines.
