Acoustic Foam Placement

Step One: Corner Bass Trapping

Low frequencies build up in the corners of your room – so that is the best place to attack them with  Bass Traps! Placing a Bass Trap in each vertical corner is recommended – starting at the ceiling. The Bass Traps should be placed between wall/ceiling horizontal junction, on the front wall (i.e. the wall you face while mixing) and on the rear wall. If you have doors or windows near your vertical corners that prohibit you from placing the Bass Traps as described, simply place them horizontally along the junctions between the walls and the ceiling as best as possible.

Step Two: Early Reflection Treatment

Reflections that arrive at your ears within 80 milliseconds of the direct sound are summed by your brain and cannot be distinguished as a separate source. This can be problematic during recording or critical listening applications. While sitting at your listening position, have someone move a mirror along the front wall, side walls and ceiling. Anywhere you see the speaker’s reflection is a good location for the placement of acoustic foam tiles. The halfway point between the speakers and your listening position on the side walls and ceiling will be crucial along with the front wall located behind the speakers.

Step Three: Ambiance Control

The rear portion of the room should be treated as well to control ambiance and late reflections. Place acoustic foam tiles on the rear wall to absorb the direct sound from the speakers.
The rear portion of the side walls should also have treatment . Additional panels should be placed on the ceiling in the rear portion of the room.
