The Sun's magnetic active regions, composed of sunspots and plage, are topologically complex. The magnetic field is highly structured, forming a tangle of fibrils within the plage and more compact, regimented bundles within sunspot umbrae. The fragmented nature of the field makes helioseismic observations within active regions rather difficult to interpret. We choose to study the propagation of acoustic waves through regions of plage, modeling the magnetic field therein as a collection of thin flux tubes. In this paper, we present the first results of this research; the computation of the absorption coefficient from an ensemble of many flux tubes. The incoming acoustic waves interact with the magnetic flux tube, exciting sausage and kink tube waves which propagate downward and upward carrying away energy, thereby producing absorption. We calculate the resulting theoretical absorption coefficients and compare with the most recent observations.
