Abstract
A series of reproducibility experiments on the characterisation of most important acoustical and related non-acoustical parameters of selected samples of porous media is carried out on a range of porous samples in several independent laboratories in Europe and North America. The studied acoustical characteristics are the characteristic acoustic impedance and complex propagation constant. The related non-acoustical parameters are the steady-state flow resistivity, porosity, tortuosity, viscous and thermal characteristic lengths. Detailed procedures related to sample preparation, installation and testing are carefully recorded and the tolerances of some common techniques for the characterisation of porous acoustic materials are discussed in detail.
