The accuracy of acoustic scale modelling strongly depends on the choice of porous absorbing materials with properties at the scale frequencies which resemble those of full size absorbers. In this paper the Attenborough impedance models are used to identify a combination of microscopic parameters, wh

Critical to the development of an acoustical scale model to be used to measure the e!ectiveness of roadside noise barriers is the selection of both a model scale and materials with which to construct the scale model. Previous work on acoustical scale modelling has typically proceeded by "rst selecti
