Road traffic noise prediction model 'ASJ RTN-Model 2008':Report of the Research Committee on Road Traffic Noise

摘要

In 1974, the Acoustical Society of Japan first organizesa research committee to develop a road traffic noiseprediction model. This committee has been undertakingresearch activities since then. As a result of its activities, aprediction model called ASJ Model 1975 was published in1975, which provided a method of calculating the 50percentile A-weighted sound pressure level (LA50) [1,2].
