Validated expressions align with prior research results
Abstract
The correct three-dimensional poroelastic field expressions, under monochromatic harmonic incidence, were revealed in this paper. They were confirmed satisfactory using the results got by other researchers. Former incomplete expressions were found to overestimate the random sound transmission loss and lead to division-by-zero, though their results were amply acceptable.
