I'll try to keep this short and sweet. I'm going to build a booth by myself. I've built one before that was super budget. But I had to tear it down recently for reasons (I did save the acoustic dampening foam). The old booth worked great and I could sing, and scream., in the middle of the night. That's what I'd like to achieve again so I won't be disturbing the neighbours. I think the booth was really dead inside and I never worried about the acoustics. I just worry about the noise. Pics from the process of building old one: https://i.imgur.com/01I7C5V.jpg https://i.imgur.com/vY7eSC0.jpg The old booth was (outside to in) Wood, isolation foam, two layers of fabric, acoustic dampening foam. Was planning on showing the whole process at some point. Though it's pretty pointless now that it's gone. I've gone through different ideas now on how to make it a cheap build (that would be easy to do at home). I really don't want to use wood board again. Hate the sawing and I want something lighter that I can tear down again if need be. There's one company that cuts board to specification but the price is too much (for me; in my situation). I plan to make the walls around 200x100cm (78.7x39.3"). The inside would then be 100x100cm. I might make it 210x95cm. Or even 90cm to save space, but still enough to fit a guitar or cab in there. The floor would have extra studs and a wooden square to stand on. My current idea is to make walls out of 45x45mm (1,77") wood stud as a frame and filling it with 45mm glass wool. Then adding some thin (thicker than regular paper) paper to seal in the wool on both sides. Then a couple of layers of paint, and lastly the acoustic dampening foam. I'll use latex sealer (for windows) in the corners, then some spray on foam to cover any airpockets in the wool and also in the corners to keep it in place. I still have to saw, but hey, it's the cheapest option I can think of. But would the glass wool be enough? Or instead of paper I could add a couple of layers of 2mm (0.078") Polyethylene foam/plastic, that's used under floors, to keep the wool in place. And then on the inside I can use a layer of polare fleece before the dampening foam. Though fabric ups the cost. The frame, glass wool, and two layers of polar fleece. = $68 = 61€ On top of that is foam and insulation for the corners, hinges for a door, and paint. Then I'll add a mat/covering to the flooring and I might need another bag of dampening foam. It's going to be twice the cost, when everything is purchased, of the estimate above. I know it's not a lot of money for some, but I'm on a tight budget.
