Microstructure representations for sound absorbing fibrous media: 3D and 2D multiscale modelling and experiments

The paper proposes and investigates computationally-efficient microstructure representations for sound absorbing fibrous media. Three-dimensional volume elements involving non-trivial periodic arrangements of straight fibres are examined as well as simple two-dimensional cells. It has been found tha...
