DIY isobooth

Copying from the Sound on Sound article (https ://www.soundonsound.com/techniques/studio-sos-building-diy-vocal-booth ), I decided to make the back of the booth a bass-trap. Basically, a 2x8 box, four feet wide and 76 inches high (inside).  Back  to front Standard fire-code 3/8 sheetrock Safe 'n Sound between the vertical supports Hung carpet Hung mass-loaded vinyl Hung carpet Acoustic fabric front This back would be anchored by 4x4 posts that would bolt to the booth walls. Namely because I'd already bought them (while possibly intoxicated), I decided to use tee nuts into the posts and have the side bolts anchor into them. Base layer of carpet anchored by a 2x2.  Mass-loaded vinyl (folded back to show the 2x2) is attached to the top of the 2x2 for extra support   Plan A was to use a 2x1 to attach the carpet, etc too.  However, once wielding the mass-loaded vinyl, I decided there was no way it would be strong enough and swapped i...

Working within the bounds of the fire code meant that the iso booth couldn't be placed anywhere that obstructs egress.  This is not just a formality but also important, given the severity of the consequences driven home by the deadly "Ghost Ship" fire in San Francisco where fire inspectors described the makeshift homes inside the warehouse as an accident waiting to happen. Luckily, I have one such nook in the back room although it's a bit smaller than I would like. But since I was aiming for a modular design, has the advantage of having sound isolation batt above the ceiling tiles. A small, 7 X 5-1/2 nook not blocking egress seems an okay location for the booth. The small size means that while free-standing, the structure would gain stability from the snug confines of the building walls. Not touching, but enough to prevent the walls bowing outward enough to allow the ceiling perched on top fall in. The plan was to build four 3-3/4 feet wide sections which...

As a renter priced out of the housing market, I live in close proximity to others which makes it difficult to practice music without disturbing others. While there are off-the-shelf solutions, they're either cost-prohibitive or of questional effectiveness (like having a big hole at the back). Since I live on the ground floor, I'm only worried about noise from the window and the ceiling. Blackout curtains help somewhat with window noise, and throwing sound isolation batt above the dropped-ceiling tiles only dampens the noise from the TV above slightly. Above the dropped ceiling are big pipes, blocking access to the floor joists above, so I can't attach an isolation system like this there. Since I can't isolate the existing room, I'd need to set up an area within that room that can be isolated. Some of the cost-prohibitive solutions are actually affordable if filing as a business and using a section 179 deduction to write off the expense.  However,...
