The C. Zwikker and C. W. Kosten model (Zwikker, C., Kosten, C.W. Sound absorbing materials, Oxford: Elsevier Pub Co., 1949) for sound propagation through porous flexible media is used for numerical calculations of some intrinsic characteristics of nonwoven fiberwebs yielding the highest sound absorption coefficients in the audible frequency range. These results can serve as guidelines for the optimal design of acoustic elements made of textile assemblies.
