The dispersion properties and enhanced dissipation of hydromagnetic waves in a random ensemble of closely packed flux tubes are studied. The procedures which allow the averaged equations containing the nonlinearity of the wave, dispersion properties of the system, and dissipative effects to be obtained are presented. The obtained results are addressed as applied to the solar atmosphere, with emphasis on sunspot regions, plages, and other regions where random magnetic flux bundles form a dense conglomerate. It is shown that in such regions the enhanced dissipation of the wave energy takes place. The presence of small-scale inhomogeneities is found to lead to the finite dispersion of the wave, and in the case with weak but finite dispersion effects, this gives rise to the cubic dependence on wavenumber of the frequency shift of an acoustic wave. Different scenarios of the energy transfer of primary magnetosonic waves to a certain region of the solar atmosphere are considered.
