I'm (hopefully) moving into a new studio space thats being built. it seems like the builder is doing a solid job of soundproofing, but I'm noticing that the treatment is being done mostly with 2" panels laid in via fabric walls across pretty much the whole 360º of the rooms.
This might be one of those things where I'm overthinking, but I was curious how most of you guys with more experience feel about these type of treatment styles? I've been told by some renown acousticians that you don't really wanna cover up more than 50% of the surfaces. These acousticians also recommend some SERIOUS thickness for bass trapping (a foot of r15 if I recall correctly). There are some nice fat clouds going in, but the sidewalls are 2" 703 and not much happening in the way of backwall treatment besides the 2" 703 fabric wall.
Since the rooms are still being built, I dont have the ability to set up a pair of speakers to check deep bass but my "clap tests" were actually pretty satisfactory in regards to general deadness/brightness.
Thoughts? Thanks!

If they’re putting 2” insulation in all the walls, and covering with fabric, I suspect it’s going to sound way too dead in the high end. And that thickness/density is not going to help your low end. If you cover the 703 with craft paper or use wood slats across it it’ll help retain a more balanced high end.
For bass I’d do super chunks or soffits in the corners. Another thing you can do is take a wall or two, like behind your monitors, and build another fake wall in front of it and stuff with thick, pink fluffy insulation. Minimum 1ft deep. Cover that with fabric and it’ll really help the bass. The ceiling cloud is a great idea also.
Keep in mind I’m not an acoustician, but I have some real world experience moving from space to space and doing a garage build out myself. I’ve learned the hard way what Not to do.

Check out the build thread I posted awhile back for some ideas. There's a link to a ton of pictures in there as well.

I’m wondering if this is the problem I have in my studio room now. It’s a foley recording booth built in the 70s. Super dead. If you’re not used to it, it almost gives you a headache. It seems everything I record is lacking high end. Not sure if it’s the gear or the room or what. |

Consider the difference between “too much mid / bottom” and “not enough high end”, as well as the time domain’s effect in our perception of frequency balance. REW goes a long way towards trouble shooting this sorta thing.

It seems everything I record is lacking high end. Not sure if it’s the gear or the room or what. That kind of space really is excellent for foley, where you need extreme, dead quiet around the recordings. It's pretty common for SFX to be stacked in many layers, so any "room signature" would build up horribly when doing a mix for picture.
But for recording music? That kind of room can really choke out the high end and eliminate spatial cues that our ears use to tell distance. I would not want to record music in a foley room. It's not terribly difficult to remedy (you need more reflective surfaces), but it can be expensive to treat a room with good diffusion. Still, it'll pay off in spades. I agree with bgrotto all the way: measure that room. Then start trying stuff: add some hard surfaces into the room to get more reflection. |

Bass collects in the corners. Trap it there. It might be a little dead, but audio volume matters in small rooms and bass needs more power/volume to drive. Bass won't develop significantly if you're listening at normal levels. You could always lay diffusion over the walls if it's too dead too.

You probably got your answer already but my experience with this is that I needed to either stack some of the 2" panels (creating 4") and/or get the panels off the wall by a couple inches (there are simple rigs for this) because having it slightly off the wall is more effective for trapping low end. FWIW, I lay diffusors on top of a lot of my panels so that the room doesn't go dead.

Use fabric over 'batting' - also available at your local fabric seller. And use upholstery or drape fabric. And wood 'latting' every 12-16" which will break up the deadening effect a fair bit. (1x3 pine works great)
