Abstract
Sound absorption of porous asphalt pavements is an important property when reducing tyre-road noise. A hybrid model has been developed to predict the sound absorption of porous roads. This model is a combination of an analytical analysis of the sound eld and a numerical approach, including both the viscothermal e ects and the scattering e ects. The model provides a description of the three- dimensional sound eld in and above the porous asphalt pavement and can be used to predict the absorption coe cient for oblique incident sound waves.
