Noise Pollution an overview ScienceDirect Topics
The level of truck noise pollution is influenced by several factors such as vehicle speeds, traffic flow (free flow vs. stop and go), road surfaces, weather, and vehicle type and conditions. The index used for noise is the energy mean sound level, [dB(A) 6]. It gives the average sound level over a given period.
