  • Recently various low-noise-pavement methods have been developed. Since tire/pavement noise is the major source of traffic noise at high speed condition, the core-technology of low-noise pavement is to produce the road surface texture that can reduce tire/pavement noise. The difficulties in the development of the low-noise pavements are high costs and time to construct test roads, since vehicles have to travel on the test roads to evaluate the noise from a particular condition of pavement surface. Tire/Pavement Noise Simulator were developed to overcome those difficulties and the reliability of developed Tire/Pavement Noise Simulator are investigated based on the simulating and measuring the noise of tire-tined concrete pavement and tire-non tined concrete pavement.

  • A survey and auditory experiment on multiple residential noises such as floor impact, airborne, bathroom, drainage and traffic noises were conducted to develop a combined rating system and to establish criteria for multiple residential noises. Subjective reactions such as annoyance, activity disturbance, sleep disturbance, and satisfaction to overall noise environment and each residential noise were recorded. The effect of individual noise perception on the evaluation of the overall noise environment was also investigated. The survey results showed that satisfaction for floor impact noise most greatly affects the overall satisfaction for overall noise environment and annoyance most greatly affects the satisfaction for individual noise sources. Auditory experiments were undertaken to determine the percent satisfaction for individual noise levels. Result of auditory experiment showed that the noise level corresponding to 40 % satisfaction is 49 dB $(L_{i,Fmax,AW})$ for floor impact and is about 40 dB(A) for airborne, drainage and traffic noise. From the results of the survey and the auditory experiments, an equation for predicting the overall satisfaction for multiple noises was developed and a classification of multiple residential noises was proposed.
