Identify Primary Reflection Points
Primary reflection points are areas where sound waves first hit a surface and reflect back into the room. These are typically the walls and ceilings adjacent to sound sources like speakers or vocalists. Placing foam panels at these points helps to absorb the initial reflections, reducing echo and improving sound clarity. Using a mirror can help identify these points; wherever you can see the sound source in the mirror from your listening position is a primary reflection point¹.

Cover Large Surface Areas
To achieve optimal sound absorption, it’s important to cover large surface areas, particularly on walls and ceilings. This doesn’t necessarily mean covering entire surfaces but rather strategically placing panels across large areas to diffuse sound effectively. This approach helps in absorbing a wider range of frequencies, resulting in a more balanced acoustic environment².

Position Panels at Ear Level
For environments like home studios, recording booths, or listening rooms, placing foam panels at ear level is crucial. This ensures that the sound waves traveling directly from the source to the listener are intercepted and absorbed by the panels, enhancing the overall listening experience. Typically, this means placing panels between three and six feet from the floor on the walls surrounding the listener³.
