ROAD TRAFFIC NOISE PREDICTION MODEL 'ASJ MODEL 1998' PROPOSED BY THE ACOUSTICAL SOCIETY OF JAPAN - PART 2: CALCULATION MODEL OF SOUND POWER LEVELS OF ROAD VEHICLES
The calculation formulae for the sound power levels of road vehicles adopted in the ASJ Model 1998 have been introduced. The relationship between running speed and sound power level on urban roads is much different from that on freeways. On freeways and urban roads under steady running conditions in the speed range higher than 40 km/h, the expression of 30log10V is adopted as the speed dependence. On the other hand, for the case of urban roads where vehicles accelerate and decelerate in the speed range lower than 60 km/h, the expression of 10log10V is adopted. For the covering abstract see ITRD E107776.
