Evaluation Indicator and Models of Time-varying Traffic Noise Based on Human Feeling
Effects on human vary between uniform and timevarying traffic noise with the same equivalent sound level. Firstly, the subjective evaluation experiment of timevarying traffic noise is designed and implemented in this paper to get truthful data. Secondly, taking the gender, employment and mood factors into account, some conclusions about the effects of traffic noise with different timevarying characteristics on human are obtained based on the test results. Then the paper defines the disturbance degree of traffic noise on human as the subjective indicator of noise evaluation, represented by Lm. Finally, taking multiple existing noise indicators as inputs and Lm as output, three mathematical models are established using multiple regression, stepwise regression and artificial neural network analysis respectively.
