How to insulate a home recording studio
When folks start making a plan to build a home studio, they usually miss a component that’s really important for the way you record and you mix songs. I’m talking about the acoustics of the recording and mixing room. The online stores are packed with audio foam panels, but buying two or three such panels and placing them behind the condenser microphone is not enough. If you want to build a quality studio, you need to learn which type of panels to buy and where to place them. The final goal of insulating your studio is to have a recording/mixing room with a dead sound (where audio waves does not bounce around, where is no reverb), so you can manipulate it later in the mixing sessions.
The recording booth
The recording booth is a closed space (usually a small room) where the actual recording is performed. There, we have the microphone, headphones, other acoustic instruments and… that’s all. For most types of music, this room needs to be as quite as possible, and most musicians prefer to add common acoustic foam panels on 100% of the surface. Since this room is small, you will not use too many such panels. If you don’t have two rooms for your recording studio, you can always build a small recording booth in a corner of your mixing room by adding to fake walls. Just look at the image above to get the idea.
The mixing room
The mixing room is usually larger than the recording booth, and placing the acoustic treatment here is more difficult. If you mix your own songs, you will spend a lot of time in this room and the acoustics need to be perfect, so you can create the perfect mix. Basically, you need to treat the most important areas of the room: the space behind the studio monitors, the side walls, the corners and the back wall.
The computer area should be the first place to start your work. Place some panels right behind the studio monitors in order to cancel the early reflections that are causing the cancellation and filtering effect.
Next, you need to take care of the bass reflections in the room. For this, you should use bass trappers and you should place them in the upper corners of the room. This way, you sill still have enough place in the lower corners to use it for anything else.
The sidewalls are also important, and you should place the foam panels at the ear level. Let them breathe, by allowing some space between them, just like in the picture above.
For the back walls, you should use two or four diffusion panels placed in the exact middle of the wall. Don’t place them in the same pattern, but rather use a pattern that’s similar to the one in the image above. If you are on a tight budget, you can skip the diffusers and get common foam panels.
If you plan to insulate your recording room so your neighbors will not hear any noise, the typical egg crate foam panels are not enough. They are great when you need to cancel the reverb of the room, but they are not so great at stopping audio waves from getting past the walls. For that, you need a material with a larger/denser mass. Maybe I’ll talk about this topic in a future post.
Don’t forget to get some type of foam panels adhesive. You will find everything in your local music store, or you can check my recommendations from the slider above.
