文摘

Upscaling of wave equation in hierarchical sorptive porous materials. Effective bulk modulus is significantly altered by diffusion and sorption. Sound waves are slowed down and more attenuated at low frequencies. Analytical models for sorptive porous, fibrous, and granular materials are presented.
