Abstract
The task of monitoring porous materials is formulated. Principles for developing and using nondestructive acoustic methods for monitoring the structure and physicomechanical properties of porous materials are suggested and discussed. It is noted that the solution of each monitoring problem for porous materials requires an individual, often nontraditional, approach and its success is determined by the possibility of developing theoretical or experimental correlation dependences between the acoustic and material properties sought. It is shown that it is possible from the results of measuring propagation velocity and elastic wave damping factors to determine parameters such as elasticity, inelasticity, porosity, defectiveness, the size of structural elements, anisotropy, and property inhomogeneity.
