Happy New Year!
If this isn't the correct forum for this, please feel free to move it.I just bought a house, a 1930 vintage two-story with an unfinished basement. My studio only needs to be one room, just enough to be able to mix in, and record vocals and occasional samples (everything else is either hardware synths or plugins). Finishing the basement is out due to expense, so that's going to become a wood/metalworking shop.My original plan was to use one of the bedrooms. It's a decent size, but there's an issue: it's square. 10'4" by 10'5" (by 8' tall), to be more precise. Now, bass-trapping the crap out of it is an option, and rockwool is readily available where I live.The remaining option is to use the first floor, and basically kit out the dining and living rooms (which kinda merge together). However, it also merges with the kitchen (the three rooms together are all kinda one L-shaped space), where I can't exactly hang traps.Honestly, I'd like to use the bedroom, as it's a quieter space and I can seal it up even more. So my question to all of you is: is there anything I can do to whip this room into shape? Searching around the web has been getting me a range of answers all the way from "don't bother" to "just bass-trap the hell out of it."I can provide more details and pictures/video of the options if necessary. Thank you!
My drum room is only 20m2. Rectangular 4x5. Also old building, acoustic pretty not bad in an empty room.I used regips and rockwool to reshape room. There's no parallel walls as also one corner is filled and remodeled (green on the pic).It don't have to be huge angle.For now it works pretty good, there's improvement (regips as also wool have their own great properties) it's of course unfinished. Drums sounds great. I will make measurements after finishing whole studio.Really great material is wood wool I'll be using it in whole studio, especially in control room.http://www.knaufinsulation.com/en/heraklithI have few other ideas for absorption, distraction etc. After using it i'll e able to say something more.Btw. rockwool need to be high density, am using 50kg/m3, but i have few layers of it. If there would be need to use for example only one layer of 10cm thick, then i would go for 80kg/m3.
When you think of the volume taken by rockwool (in order to be effective, you need at least 20cm (8"), for a total volume of about 3 cubic meters, you may see a strong case for using less rockwool and using some a the volume for building Helmoltz resonators. That's what I've done in my control room, where the absorbent is 70mm polyurethane foam on the walls and 50mm Basotect foam on the walls. From the measurements, I think this takes care of most of the issues above 500 Hz. I've built 3 Helmoltz resonators that take a total volume of 1 cubic meter. They are tuned to the primary measured eigenmodes. I found I had to apply very little EQ to sort out the remaining issues (using the Room Mode Correction that comes with the JBL 4326). Helmholtz resonators can be built in the form of a desk, on which one can put tape recorders, effects, keyboards... or a bench where you can put your girlfriend or a client, ;Dso they would not be too obtrusive.Since it's a small room (4x3x2.5m), the "sweet spot" is quite small, though.
