Studio Acoustics

Building a home studio is an exciting opportunity for you to construct a professional-level recording space within your own walls. Assuming your studio is equipped with basic equipment such as:

  • Computer
  • DAW Software/Interface
  • Microphone
  • Cables
  • Monitors



But did you forget something? What about your ROOM?

There are many factors that are important to the overall sound of your room. The main ones that you should consider are the size and shape of the room along with its surface materials. These will determine how the sound is shaped, regardless of the equipment you are using. Even if your room is less than perfect, using Absorption, Bass Traps, and Diffusion in a space can help control sound in the room.

It’s The Room…

How does Auralex determine where panels should be placed? The generally agreed upon thinking behind room acoustics is a fairly straight forward process. Let’s walk through the thinking behind it.

Finding the “Sweet Spot” AKA Set-up Your Mixing or Listening Position

Before you even treat the room there are few things you can do to help ensure you are getting the most out of the sound in your space. Best of all, these are things you can do easily and for free! Follow the animation to see all the steps.

***Note that these are very basic instructions, you can get much more in depth with each of these aspects if you choose do so – but we wanted to try and keep this simple for our example.  Remember these are not “hard and fast” rules, but simple, yet effective ways to try and minimize axial and modal issues in a smaller, rectangular-shaped room. The correct method for you and your space may be different, so you should try different placements yourself and listen to the results.


A. Move your mix/listening position to the 38% point of the room. This is a method developed by world-renowned Studio Designer, Wes Lechot and works very well in the majority of simple, rectangular rooms. Take the longest dimension of your room, 12 feet in our example and multiply it by 0.38 to get 38% of the overall length. 4.56 feet in our case, this is where your chair/listening position should be located (not your speakers).

B. In order to achieve sonic accuracy it is important to have as much symmetry as possible. To this end make sure to Center your desk, speakers, and listening position in the room the best you can.

C. This step is where some sources start to offer conflicting information and some answers (or the math behind them) can be very complex. We will try to stay somewhat basic and follow the details that are generally agreed upon by most major players in the Acoustics/Music industry. Your monitors should placed pointing at a 45° angle inward towards the listening position. The monitor’s tweeters should be placed at ear level – typically 48″-50″ high. Lastly, there should be a60° Angle at all three intersection points of the large Equilateral Triangle, this means all sides should be the same distance – ideally 67.5″ if possible.


Treat Yourself! 5 Steps for Acoustic Treatment

1. Add Bass Traps: The first step for acoustic treatment in any small room should be to place Bass Traps in all of the corners. If you have a more limited budget concentrate on placing traps (and all treatment) at ear level – about 30-36″ off the ground. If you have an uneven corner or some other anomaly that doesn’t allow for all corners to be treated vertically – Bass Traps can also be placed horizontally. As mentioned in the steps above symmetry is important sound accuracy, so try to maintain as much as possible.

2. Treat Front Wall: The next step is to place treatment behind your monitors and mix position. This helps to tame secondary reflections or slap back echo from the rear wall.

3. Taming Early Reflections or First Reflection Points: Think of the way the sound waves emanate from a speaker – they radiate in all directions on a 3D plane similar to the animation shows after Step #3. This initial contact isn’t the big problem, but rather the reflections that happen after a sound wave reflects off a hard surface like drywall or a concrete floor. These can cause common problems like slap-back echo and reverberation. To correct this you need to first locate the First Reflection Points. The easiest way is use a method called the “Mirror Trick.”

For this you will need a mirror and a friend. Sit in the mix position and have a friend move the mirror along the wall at the same height as your monitors. When you can see the monitors in the mirror, make a mark or the wall or use tape to note that area.

4. Place Treatment at First Reflection Points: The locations you identified with the mirror trick are reflection points and this is exactly where you should place acoustic treatment.

5. Add Ceiling Treatment: Directly above the Mix Position is a place where treatment is sometimes overlooked. This is definitely a place where reflections from the ceiling can cause a problem for critical listening.
