I got up into the attic above my studio this weekend, because I have this leftover rock wool sound insulation, and wanted to see whether I could further dampen the occasional airplane noise that makes it through everything.
I’ve never lived in a new-construction house before. This thing was built in 1998-2000. (Why such a wide date range? Because this.) I’ve always lived in old buildings. Attics are dark spaces with 2×12 joists and random boards lying about and forgotten storage and knob and tube writing (sometimes just remnants) and hopefully bare-bulb light-fixtures and places where they took out the pull-down staircase and probably spiders and possibly livestock and almost certainly not ghosts.
This attic? Basically, this attic has no goddamn floor at all. Turns out the top floor ceiling is just wallboard held up by 2x4s, which are in turn hidden and drowning in an ocean of blow-in insulation. And while blow-in insulation is awesome – I’m all for insulation – having literally no visible places to step is not awesome. It’s like the end of the world in Skyrim. LOL NO FLOOR ANYMORE HAVE FUN WITH THE OCEAN.
I’m not walking around up there, much less putting in rock wool. And while, okay, 2x4s, they can hold up wallboard, and hopefully me at least briefly, and hopefully all that blow-in insulation but I’m not convinced, I’m mostly in the category of whose idea is this?! Can wallboard ceilings hold up rock wool? I would think so, but I don’t even know! Hell, I’m not even enamoured of it holding up that much blow-in thermal insulation because that is a lot of insulation up there.
Basically what I’m saying is that compared to what I’m used to, this attic “floor” is made up of assurances which are made up of lies. So I’m not remotely surprised I hear airplanes through it.
What do I do here? Continue to live with it? I mean, it’s only occasional, and it’s at -60db when I do hear it at my normal recording levels, so even if it happens during recording it’s not that big a deal. Do I tack up another layer of wallboard to absorb low-frequency airplane noise, maybe on floaters of some kind? Do I make rock wool pillows and hang them from the existing ceiling and try to compensate for the brightness loss by taking out other baffles? Will this all literally come tumbling down on my head if I do any of it?
I’ve no idea. And really, I suppose it’s not that important. But it tasks me. It does, it does.
