I've been working away on the studio - lots of progress, with more coming every day.

The plywood walls have been covered with normal wallboard, so the room looks "normal", but the extra density in the walls has really cut down the sound in and out of the room.

I hung 19 bass hangers up in the sloping ceiling area. The biggest 2 were 4 feet by 8 feet, and the smallest was 4 inches by 8 feet.

Here's the one of the big hangers. We screwed strips of wood onto the ceiling with plastic zip ties already attached. We then used a pulley to pull the panels up, and secured them with more zip ties. We used 6 zip ties for each panel. The heaviest panel was about 45 pounds. Each zip tie is rated at 50 pounds, so it should be fine.

Here's all the hangers installed.

Below the hangers, I have 4 inch thick rigid fiberglass sheets (Owens-Corning 703) wrapped in muslin. I didn't want to use a conventional drop ceiling, because I didn't want wires going up from the drop ceiling through the hangers, so I used 2x6 lumber across the room with a 1x4 on the bottom to hold the drop ceiling tiles.

After putting the tiles up, I used a steamer on some of them. The cotton cloth shrunk nicely, and looks pretty good. Eventually, I'll steam all of them.

I ran into one problem - the AC vent was up above the drop ceiling. As it turned out, that was a good thing after all. I built a box lined with muslin wrapped 703 which takes the horizontal outlet and redirects it vertically, while keeping the sound isolation.

Here's the finished box. The air flow works really well through it.

Here's the ceiling after a bit of painting and hanging of the lights. I still need to steam some tiles. In the back you can just see the edge of the studio door - it's a double door with an extra nice seal on the inner door.

The floor has been installed.

I've been working on the interior covers for the windows. Just about done - but these things are HEAVY.

Next up - slot resonators!
