So what material should you use in your acoustic treatment in your studio? Most folks use FOAM. However, many pros avoid using foam for several reasons. For one thing, tests using foam and fiberclass show that foram doesn’t do a great job absorbing lower / bass frequencies. This isn’t to day foam is no good. It’s a good way to cut down on first order reflections and cut down on too much treble bouncing around.

In a professional studio, the walls of have panels that can be flipped to be either absorbative, or reflective. In a home setup, we usually don’t have that kind of flexibility due to cost. So home studios are usually set up to limit room resonance and standing waves, early reflections etc. This is important, especially in a small room and a room that is mostly square which is prone to creating standing waves or resonance at certain frequencies.

First of all, you need BASS TRAPS. These are typically larger pieces of treatment that typically cost more money. You can buy foam bass traps, bu they typically don’t do as good a job as traps made from thicker material like fiberglass. Custom made bass traps can be very very expensive. They cover from 10hz to about 700hz. These are the troublesome frequencies that tend to make a room sound like it has too much bass. Then when you check the mix in the car, it sounds thin. So getting rid of this is crucial. Putting bass traps in the corners of your room can cut down on this. Some people put bass traps in the bottom and top corners of the room, in each and every corner. Some folks build their own traps, but most folks will just buy traps. Some of them go from floor to ceiling and fix the problem in once piece.

In addition to adding bass traps, just adding some furniture, like a couch can help absorb extra low frequencies. If there is a gap under the couch, so much the better. Even adding big soft chairs can help. Anything soft that is not reflective to audio can help reduce audio bouncing around in your room.

Another thing to avoid is “FIRST ORDER REFLECTIONS” basically, sound bouncing off the walls near your monitors. You end up hearing a bit of reverb in the room your mixing in. Sound bounces off of everything. The floor, the desk, the ceiling, etc. So it’s important to try to treat these areas so your listening location is as reflection free as possible. A panel on each side, on the floor and even something to dampen the desk. On the desk itself you can add a slanted shelf to get the audio reflections to bounce away from your ears.

If you want to get more in to it, you can use software like SONAR WORKS to test how your treatment is working. Here is a link.
