In materials science, a porous medium or a porous material is a material containing pores (voids). [1] The skeletal portion of the material is often called the "matrix" or "frame". The pores are typically filled with a fluid ( liquid or gas ). Porous materials are widely used as a sound ab-sorber for many practical applications. Models of the acoustics of porous materials include an empirical model (Delany, Bazley, 1970), analytical models (Allard, Atalla, 2009; Zwikker, Kosten, 1949), semi-phenomenological models (Johnson et al., 1987; Champoux, Allard, 1991; Lafarge et al., 1997)
