For the measurement of sound power level of vehicle noise in constant speed run, a new method using a reverberant tunnel is investigated. This measuring method is a kind of sound source substitution method in a reverberant sound field, which makes the measurement easier and more accurate, compared with the ordinary method. By making a field measurement on road vehicles in actual use using this new method, 179 data of passenger cars and 490 data of heavy vehicles were obtained. Concerning these results, the correlation between A-weighted sound power level and such vehicle properties as running speed, total weight, and type of tires are investigated.
