Electrical outlet box acoustic seal
An electrical outlet box acoustic seal includes a seal body formed from a flexible sound suppressing material. The seal body has a front side, a rear side, and a peripheral edge. A seal rear projection extends from the seal rear side. The seal rear projection is configured to wrap around a front peripheral edge of an electrical outlet box having left and right sides, top and bottom sides, a rear side, and an open front defined by the outlet box front peripheral edge that provides access to an outlet box interior. When the outlet box is mounted in an opening formed in an architectural separation, and when the acoustic seal is installed on the outlet box, the seal rear projection inserts into a gap between the outlet box front peripheral edge and the opening of the architectural separation to assist in blocking noise transmission through the gap.
