Acoustical Porous Material Recipes (APMR)

section: Home | Parameters of models | Characterization of parameters

This page currently hosts two web applications to estimation the open-porosity and the static air-flow resistivity (shorten to resistivity) of acoustical porous materials from impedance tube measurements. These applications follow the technique described in Estimation of all 6 parameters of Johnson-Champoux-Allard-Lafarge model for acoustical porous materials from impedance tube measurements by L. Jaouen, E. Gourdon, Ph. Glé published in J. Acoust. Soc. Am. 148(4), pp. 1998-2005, 2020 :

Estimation of open-porosity from bulk modulus

Estimation of resistivity from mass density
