Abstract
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.
