Frequently asked questions

How many absorbers do I need in my studio or at home?

Every good music studio or rehearsal room is equipped with absorbing or diffusing panels on more than 50 % of the wall area, with absorbers playing the major part. For home listening room or home theater, you’ll want at least 20 %. In more spacy commercial spaces like office or in restaurant, you will need more tailor made solution.

Where do I place the absorbing panels?

You always start with covering the first reflection points between the source of sound and the listening position to eliminate the early reflections. If you don't do this, the sound waves reflected by the walls will be interfering with the direct waves from the speakers and the resulting sound won't be clear and balanced. Check out our acoustic helper to get more details on this.

Why should I even use the acoustic treatment?

Once you hear the sound from the acoustically treated room, you will never want to listen to music anywhere else again. Such a clear sound without any coloration! The same applies not only for music, but for a whole range of applications.

For example, in spaces like living room, office or restaurannt, you will love the calmness and noise reduction by absorbing the excess sound reflections from the various sources (people talking, loud steps, music in the background, etc).

Acoustic treatment simply brings you comfort in your life.

What is the difference between absorber and diffuser?

Absorbers take in the sound energy when the sound waves hit them and transform it into heat. This is useful when controlling the reverberation time of the room (how much echo can we hear) or reflections of the wall that are causing sound coloration at the listening position.

Diffusers do the exact opposite of absorption, but in more clever way. They evenly distribute the sound waves into the room by scattering them from the ragged or else irregular surface. By creating this even diffuse field, diffusers maintain the sound energy in the room and make the music feel spacious and lively.

How many diffusers do I need in my room?

Diffusers need to be at least few meters wide or they need to be placed in array to make a difference. Since our goal is to create even diffuse field that will make the sound more lively, we need to line a whole array of diffusers next to each other to scatter as much energy as possible.

The highest diffusion effect is accomplished when we place 5 and more diffusers next to each other. There is the math behind it, but to simplify it, the more periods (diffusers next to each other) there is, the more even the energy gets distributed. And that's what we want. If your diffusion panel array is less than one meter wide, you wil probably not hear much of a difference.

Where do I place diffusers?

On the rear wall. That is the most popular option in music studios, listening rooms, home theaters or other musical spaces. The idea is that if you place your listening position far enough from the rear wall (at least 3 meters), the diffusers on the wall will have enough space to evenly distribute the energy and you will get the best experience.

On the side walls. If you don't want to use only absorbers on the first reflection points and want to preserve more liveliness in your room (usually high-end listening rooms), you can place the diffusers on the side walls between speakers and the listening position as well. The important thing is that the first reflection points are covered and the energy is not reflected by the flat walls directly at the listening position.

On the front wall. This option is suitable for audiophiles, who alread treated their rear wall with diffusion and want to add even more spaciness to their music. You can create effect of 'endless space' by having two opposite walls covered by arrays of diffusers so the energy is almost never reflected by the flat surface.

Should I always use the diffusion?

We don't recommend placing diffusers on a wall if you don't have enough room to let the energy evenly spread out before it reaches your ears at the listening position. This means at least 2 meters from the rear wall or more. If your room is smaller, invest more of your time to tame the low frequencies and flutter echoes.
