The difference the panels add to such a small room is astounding though.
Acoustic panel placement mirror trick.
But if your room is already built there is an easier way to find your first reflection points.
I too noticed upper bass.
This is great news.
This lets them plan a reflection free zone around the listening position before building the room.
Acoustic panel placement the mirror trick.
Absorption is a very popular method of acoustic treatment because it is both readily available and relatively inexpensive.
The easiest and cheapest way to treat your first reflection points is to use broadband absorption.
Hi all i am setting up my acoustic panels tomorrow and was wondering about the mirror test.
Recording studio designers and acoustical engineers use a technique called ray tracing to find early reflection points.
2 inch thick panels are an absolute minimum.
Sound above 400hz is considered to be directional.
You will notice the improvements.
My room is an odd shape and curious if the mirror should be held flat against the wall or 90 degrees to the wall.
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.
We suggest ceiling clouds be at least 12 inches deep.
4 6 inch thick rockwool or rigid fiberglass acoustic panels will do the trick.
Fwiw the panels in my room are mounted horizontally on the sides.
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.
In most cases you re better off with thicker panels e g 8 inches because they absorb to lower frequencies.
In fact the higher the frequency the more directional the sound waves tend to be.
It may not matter but i had to ask.
Call a friend.
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.
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.
Acoustic foam works by reducing the amount of sound energy within a room.
Best to have an acoustic measurement system to place them correctly and do before after measurements.
Placement of listeners within the room.
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.
