Analysis of the influence of different means of transport on the level of traffic noise

One of the factors influencing the level of traffic noise is the type of vehicles moving on the roads. The paper presents comprehensive research, as conducted by the authors, which sought to assess the traffic noise level generated by different means of transport. A comparison is made between the noise generated by personal cars, a truck and different types of motorcycle. The maximum sound level and the equivalent sound level emitted by the investigated means of transport were analysed in the entire frequency band and in the individual 1/3 octave bands. Based on the research, conclusions have been formulated regarding the influence of the different types of means of transport and their speeds on traffic noise near a road, along with possible ways to reduce its level.
