“…Using linear curve fitting, the difference between pass-by and OBSI data was observed to be 24.5 dBA. A similar difference was also observed in a later study [64] where both types of testing were conducted at a test track in the state of California, and again the pass-by measurement position was 7.5 m from the driving lane. They registered that the difference between sound pressure and sound intensity was 23.9 dBA.…”

“…Furthermore, European authorities recommend in excess of 20% air voids to be considered as a noise beneficial porous pavement [10]. A number of researchers [3,11,64,87,88] specified that an OGFC surface reduces noise significantly (3 dBA to 5 dBA) compared to a DGA surface. The air trapped between the tire and the pavement surface moves to void space available within the porous surface, thus reducing the 'horn effect' of noise amplification.…”

“…Ongel et al [51] observed that a typical porous asphalt surface (air void content 10% to 20%) generates up to 4.5 dBA less noise compared to a dense HMA surface. The same conclusion is drawn by a number of other research studies [4,5,29,38,39,52,53].…”

“…Figure 1 adopted from the Little Book of Quieter Pavements [2] shows the effect of speed on vehicle noise sources and the crossover speed. Further study by Donavan and Rymer [5] quantified the contribution of noise generation from specific sources, as shown in Figure 2. They presented that about 78% of the noise generated is due to tire-pavement interaction, whereas 12% and 10% of the noise is contributed from the power train and aerodynamic system, respectively, at speeds of 100 to 110 km/h (62 to 68 m/h).…”
