Sonora® Sound Shim™

Sonora® Sound Shim™ wall panels are used for acoustical absorption combined with a strong design element.  The taper, from 1” to 3” thick, creates excellent low-frequency absorption, with the added bonus of a unique architectural flare. Sound Shims™ are suitable for auditoriums, worship spaces, critical listening environments and any room requiring great acoustics.

The core construction is a 6-7 PCF tapered glass fiberboard, wrapped in acoustically transparent fabric. Finishes are returned to the back for a fully tailored edge.
