Does it matter where you put acoustic foam?

Acoustic foam is a soundproofing material which is used to improve the quality of sound and reduce sound reverberations inside a room. Placement of acoustic foam is very important and random placement could lead to inefficient results.

Proper acoustic treatment is necessary for every setting where critical listening is sought. You can start to worry about where and how to arrange them when it comes to placing them. The correct response can vary significantly depending on the objective you’re trying to achieve.

Acoustic panels should be positioned in the middle of speaker reflection spots to manage surround systems. Acoustic panels should be placed where sound is being created to control speech noise.

There are many specifics to consider, such as what to do when trying to control sound for music or podcast recordings or how to determine whether your ceiling needs acoustic panels.

How do I know where to put my acoustic foam panels?

Acoustic foam panels are usually placed:

  • Along the walls
  • Along the Ceilings
  • In the Corners
  • Along the surfaces that are parallel to each other

The main principle behind the placement of acoustic panels is to absorb sound and reduce reflections. So, the positioning of the source of sound becomes really important while installing acoustic foam.

I recommend hiring a professional if you’re building a studio or you need it for a professional purpose where quality of sound is crucial.

Placement of Acoustic Foam also depends on characteristics of the room and the type of sound to be absorbed.

Where to position the acoustics?

  • Early Reflection points: Treat the first horizontal axis reflection points first. Sit in your listening position and visualize where the sound from your speakers strikes your side walls and reflects back to you if you’re unsure of where this is. Acoustic treatment should be placed here to increase stereo width and clear your imaging.
  • Weaker areas: Consider installing some acoustic treatment between your front wall and the speakers. Using acoustic treatment here, you can lessen reflections coming from your speaker’s rear.
  • Corners: Install some of your acoustic foam in the room’s corners. The ceiling and side wall, or even two horizontal walls, might be used for this. You may start by doing this to absorb those low-frequency resonances.
  • Making Acoustic Cloud: Aim to erect an acoustic “cloud” above your listening area or musical instruments that hangs a few inches from the ceiling. If your ceiling can drop down and hang, doing this will be simpler.
  • Using Furnishings: On the rear wall of your room, acoustic treatment can also be positioned immediately behind you. Placing a couch here can also be very helpful; remember that any soft, porous material can absorb sound.

When used excessively, acoustic foam can make a room sound lifeless, imbalanced, and artificial. However, it can be excellent when utilized as a first step toward acoustic improvement.

This is regrettably all too prevalent and does not produce the finest sounding room for music production or recording.
