Comparison of the Theory with the Results of Measurements of Fluid Filtration Noise in a Porous Medium

A method for remote studies of structurally inhomogeneous media is considered: study of filtration noise. A brief description of the previously proposed model for the occurrence of filtration noise is given. The results of calculations are presented, and the features of the internal structure of natural porous materials that govern the generation of acoustic emission, are noted. The calculation results are compared with experimental data recently published in the journal “Acoustical Physics”. Satisfactory agreement is demonstrated between prediction with the proposed theoretical model and measurement results. This opens up possibilities for determining the parameters of porous media and fluid velocity by measuring the filtration noise.
