Abstract

Theoretical models and experimental data taken primarily from the literature provide predictive capabilities of the sound speed in porous materials and hence their acoustic impedance can be determined. Applying the acoustic approximation (weak discontinuity) at the interfaces of the porous material along with an attenuation model describing conditions within the porous system good fits to shock tube data on an elastomeric foam and on layers of kevlar were obtained.
