Brook,
For years, 40 Frames (and previously Lighthouse Cinema and Four Wall Cinema)
used a plywood box lined with 3" foam insulation and covered with egg shell
foam. The port glass
also had foam on the edges to help dampen things and prevent the noise form
traveling out the front of the booth.
The projectionist gained access through two hinged doors that when closed
did an extremely good job of silencing the projector. This box originally
came from a classroom at the NW Film Center, and has since returned to them
and is still in use in one of their classrooms.
Cinema Project also built a box that traveled with them to several
semi-permanent venues. Their box looked pretty trick... you might ask them
about how they built it. I believe it fit two projectors inside for doing
quick reel changes from projector to projector.
