Described is an acoustic face comprising a solid polymer resin and coarse aggregates embedded within the solid polymer resin, and an acoustic panel assembly comprising at least one frame with a central opening in which a pair of the acoustic faces are mountable in opposed and spaced-apart relation to each other. The coarse aggregates of the acoustic face and panel assembly enable the acoustics to benefit highly from the mass law, efficient manufacturing and cost savings on materials.

I claim: 1. An acoustic face comprising a cured solid foam-type polymer resin and coarse aggregates embedded within the solid foam-type polymer resin, wherein the coarse aggregates have a density greater than the density of the polymer resin, wherein the coarse aggregates are embedded within the polymer resin when the latter is in a flowable form prior to curing such that the acoustic face is an integral one-piece structure and wherein the foam-type polymer resin fills the interstitial space between the coarse aggregates providing flexibility.
