Identification of noisy vehicles; Meluisten ajoneuvojen yksiloeinti

Technical Report:

Abstract

The target of the research is to study the noise caused by vehicles, the possibility of finding especially noisy vehicle groups and the factors making a vehicle especially noisy. The noise emitted by vehicles is investigated as required by the reference value for the equivalent continuous sound pressure level in the Nordic road traffic noise model. A reference noise level has been defined and measured for each vehicle. Different vehicles can be directly compared with each other on the basis of this noise level. The reference noise level is directly comparable with the emitted reference value (68 dB) for the equivalent continuous sound pressure level in the traffic noise model. The mutual relationship between the noise and speed of a vehicle in the model has also been examined, and the algorithm in this research differs from the algorithm of the model concerning the parameters. The dependence of the noise on the speed of a vehicle in the road traffic noise model turns out to be too sharp. In the model the equivalent continuous sound pressure level grows 9 dB as the speed is doubled, but according to the results of this research the growth is only about 5 dB. The  More>>

The dependence of the noise on the speed of a vehicle in the road traffic noise model turns out to be too sharp. In the model the equivalent continuous sound pressure level grows 9 dB as the speed is doubled, but according to the results of this research the growth is only about 5 dB. The gross weight of a vehicle is found to be an effecting factor in the vehicular noise. Of the other factors examined, e.g. the age of a vehicle is not found to effect on the vehicle noise, at least not at high speeds. The light vehicles are divided into three classes according to their reference noise level, the width of the middle class being 2 dB, and the other classes consisting of the lower and the higher group levels outside the middle class.}
