Since remodeling our old shop space into a gallery, showroom, meeting space and materials library, we have been contending with awful acoustics in our meeting room.
To allow the light from southern skylights to travel throughout the space, the top two feet of the inside walls are glass. This allows light in, creating a cozy space, and allows sound to bounce like crazy, creating a non-cozy echoing cave.
The solution? Look to our friends, the sheep. We found some fabulous "eco-felt" -- undyed, minimally processed wool that is felted and sold in large rolls. We ordered some, adheased it onto plywood panels, and with Andy's simple and miraculous hanging solution, fastened them to the ceiling.
Viola! A cozy, naturally fire retardant, acoustically pleasing result.
