With my broken toe keeping me home this last week, I decided to try getting some better sound happening in this apartment: I broke out the M-Audio CX5 monitors. In visualizing the setup of my new apartment, I figured I would be putting the studio in the corner farthest from the couch. There’s a lot of space there and the speakers would be able to fire out into the room instead of reflecting off walls to my sides. Since I’d managed to get the big desk setup before injuring myself, I placed the speakers on there, connected them to a little Behringer mixer, and hooked up my iPhone to hear the results.
Crap.
Actually, I’m not sure if “crap” is an appropriate term here. How about “Holy crap this sounds terrible!” That’s more of what I was thinking. For a musician living in an apartment, this place is sort of a blessing and a curse, and it’s all due to the pure concrete walls, floor, and ceiling surrounding me.
The good: Being that the walls are concrete, it’s very hard for sound to leak through the walls and annoy my neighbors. And I’m not just talking about treble frequencies, but bass frequencies as well. Bass is often the hardest thing to control in an apartment building. The bass can pass through the walls, run along floor joists, and end up in many apartments even at quiet volumes. This usually puts the nix on any sort of quality home entertainment center (5-channel surround with subwoofer) and definitely puts the kibosh on a music studio.
The bad: Being that the walls are concrete, it’s very hard for the sound to leak through the walls and annoy my neighbors, thus the sound is reflected back into my room where it creates massive reverberations with a surprisingly long decay time. When any sort of bass frequency is released in this room, it bounces around all over the place at a specific pitch–it sounds like my head is inside of a bass drum shell. The built-up frequencies are so strong, in fact, that I cannot hear the pitch of the bass that’s coming out of my speakers. It’s completely gone. Without a doubt, this is the absolute worst place I’ve ever tried setting up a pair of monitors.
Something must be done about these reverberations or I’ll need to buy an amazing set of headphones. Normally, a person would resort to mounting acoustic foam on the walls to minimize the reflections. Indeed, this will help a bit in my case, but it will only dampen the high-frequency reverberations (which are definitely bad in here). But the foam won’t do squat for the bass frequencies. Because the bass frequencies are so long and so strong, they’re the hardest to control. To wrestle them into submission usually requires serious physical reworking of the room including finely-tuned bass traps (aka huge hollow boxes) positioned in key, but not necessarily convenient, locations throughout the room.
I obviously want to avoid installing bass traps in my living room, so I’ve had another idea: The Auralex MAX-Wall. This is a system of broadband absorption panels that can be set up on stands to create a temporary sound booth. There is a system that would create 4 walls 5 feet high and 4 feet wide each that could then be arranged to separate my studio workspace from the rest of the living room. If I also put foam padding on the walls in that corner of the room, I may be able to create a fairly dead sound-pocket within the living room where I can work. The MAX-Wall would attenuate some bass on its way out into the living room and it would attenuate the reverb from the living room that may try passing back through the wall again. Double-attenuation of bass coupled with massive high-frequency damping may solve the problem.
Admittedly, this solution would not be particularly sexy. This living room is nice right now because it feels so open. Setting up this wall will shrink the size of the room quite a bit. And, unless I missed something on their website, Auralex doesn’t make this MAX-Wall in light colors. They only seem to have dark colors like charcoal gray, deep purple, or burgundy which would really make the room seem smaller.
So it seems I’m stuck between concrete and a MAX-Wall. What should I do here? Should I not even try this and basically give up on having a proper studio at my place? Sure, I can still work on headphones but, as any sound engineer will tell you, achieving a great mix is really hard to do on headphones due to a loss of certain psycho-acoustic characteristics inherent with speakers in a room. Relative volumes get harder to judge, the stereo field gets exaggerated, and even bass pitches can be transposed.
If I do go this wall route, it won’t be cheap, so I welcome any suggestions from anyone who may be reading this. What do you do when you’re stuck inside a concrete room?
