Acoustic panel placement the mirror trick.
Acoustic panel placement mirror trick.
In most cases you re better off with thicker panels e g 8 inches because they absorb to lower frequencies.
My room is an odd shape and curious if the mirror should be held flat against the wall or 90 degrees to the wall.
I didn t have to worry about placement because the room is only 11 x10.
The easiest and cheapest way to treat your first reflection points is to use broadband absorption.
It may not matter but i had to ask.
Place the panels on the hard surfaces to the left and right of the mixing position and the ceiling cloud above which is the minimum treatment expected.
Absorption is a very popular method of acoustic treatment because it is both readily available and relatively inexpensive.
2 inch thick panels are an absolute minimum.
In a home theater or 2 channel listening room these bounce off the nearby walls and produce very noticeable second order reflections which compete with the direct.
If i lay it flat on the wall along one wall i won t.
Realizing many people don t want to drop 250 on the hardware for that the mirror trick will get you in the ballpark for placement.
The difference the panels add to such a small room is astounding though.
Acoustic foam works by reducing the amount of sound energy within a room.
We didn t do the geometry calculation but used a mirror instead to find the best placement.
I made this visual to simplify the explanation.
Placement of equipment within the room.
First reflection point mirror trick and placement i did the mirror test with a mirror that was the same length as the panels and found that i could see a reflection of the speakers when the mirror was touching the wall i am facing in mix position the monitors are 6 inches from the wall can t move them back any farther unfortunately to.
But if your room is already built there is an easier way to find your first reflection points.
Best to have an acoustic measurement system to place them correctly and do before after measurements.
Sound above 400hz is considered to be directional.
Recording studio designers and acoustical engineers use a technique called ray tracing to find early reflection points.
Fwiw the panels in my room are mounted horizontally on the sides.
The panels on the front wall are mounted vertically mostly because they would not fit horizontally.
You will notice the improvements.
In fact the higher the frequency the more directional the sound waves tend to be.
I too noticed upper bass.
4 6 inch thick rockwool or rigid fiberglass acoustic panels will do the trick.
We suggest ceiling clouds be at least 12 inches deep.
Placement of listeners within the room.
This is great news.
