https://www.gearslutz.com/board/showpost.php?p=13134803&postcount=30 …just a couple of notes I’ll share from my build - Soundproofing is nearly impossible #1 - even if done by a professional - As has been mentioned there is no secret, it’s all about decoupling- dense mass - and air / space. - Stay away from mineral fiber or fiberglass, it’s nasty stuff and almost all of it, including #Roxul - the standard, contains #formaldehyde a carcinogen - Also if you are going to use plywood almost all of it contains #formaldehyde - so look for soy based glue plywood & Denim/ cotton insulation - #GreenGlue sealant is the same price or cheaper than others if you shop online, (it comes in 28 ounce tubes), and is not noxious like the regular stuff - Use 5/8 type X drywall, at least for your first layer - it’s cheap, even with green glue compound, and if you are going to use GG, buy the 5 gallon, it’s cheaper - don’t use metal studs for framing modular / movable panels - it’s too hard to work with - don’t cover your denim insulation with plastic - you kill the sound absorption properties - cover with canvas you can get at Home Depot cheap - make panels small enough, if they are not permanent, that they can be moved - ideally by one person - don’t use 2x4’s, especially for modular because there is no need to, you can use 1x’s (for walls / panels) - cellulose is the best alternative for cost and health for permanent setups in a studio but not in an iso booth, the borax smell is like cat piss - a resilient channel with clips is ideal, look it up… Just some things I’ve learned the hard and expensive way sometimes over the last 6 months of on again, off again soundproofing my place and currently an iso booth. So many hours and learning, and I continue to… Everything in this process takes time so prepare yourself, everything needs to be sealed and not touching and/or padded to stop the sound/ vibrations. A real iso booth needs to have a ventilation system, what I’m working on now… I’ll post a link to some pictures soon, and / or post them on my website http://www.seanryderwilliams.com. As well as a proper blog there of my experiences… Hope this rant helps someone. Just another sometimes necessary evil, like computers for recording music… Cheers, - Sean Ryder Williams #seanryderwilliams #seanryderwilliamsmusic
