Acoustic Panels – What & Where


Hi I’m John Calder of Acoustic Geometry
We talk with thousands of people about acoustic panels
and they all ask us “What?” and “Where?” So what are acoustic panels?
There are two types: Absorbers and Diffusors and they’re both important to improving the
sound of your room We’ll start by finding the first reflection
points which are simply the places sound bounces
after leaving your speakers on the way to your ears.
First reflection points have the first and worst effect
on sound in rooms. I’ll use my Nerf gun to find the first reflection
point on this wall. Of course, you may not want to find your first
reflection points like this.
So here’s an easier way. Get a handheld mirror
and an assistant. Slide the mirror along the wall until
your assistant sees the speaker’s tweeter. Mark that spot with painter’s tape.
Then repeat on the other side. Now you’ve marked your first reflection points
on the walls. Which panels go there?
Lots of people put absorber panels in their first reflection points, and that’s
ok. But a better option is to use our Medium Curve
Diffusors in those pesky first reflection points.
It’ll make your stereo sound stage wider and more
focused because our diffusors are phase-coherent. Flat surface reflections happen on all four
walls. So, let’s place one Small Curve Diffusor on
the back wall and one on the front wall.
We’ve mounted the front wall diffusor horizontally because sound moves in three dimensions
and it fits with the TV. Because corners make sound bounces worse,
we’ll use a Fabric Wrapped Absorber panel in each corner.
Two in front reduce side-to-side reflections and two in back reduce front-to-back reflections.
That’s it for the basics. These eight acoustic panels will definitely
improve the sound of your room and might be all you
need. All rooms are different.
And your room may need more sound control. So, let’s look at the next group of treatments.
The ceiling is a big, flat surface area and should be treated.
Ceiling absorber panels are called Clouds. Two are placed at the ceiling first reflection
points and two over your seating area.
Or you could use our Silk Metal absorber tiles if you
have a drop-in ceiling grid. These are cutting edge microperf technology.
We’re also adding a Fabric Wrapped Absorber panel in each corner.
Further reducing corner sound problems. And we’ll add one more Medium Curve Diffusor
on each side at right-angles to your seating position,
which is where the most annoying flutter echoes occur.
And that completes our first two groups of acoustic treatments.
There’s one more group of improvements, if needed.
Place a horizontally-mounted Small Curve Diffusor between each of the two sets of side wall
Medium Curves and place our Curve Corner Traps in
any two of your corners.
You can also add two to four more Clouds. As you can see, you don’t need to treat
every square foot to have great acoustics. Remember, your panels and layout will depend
on the size and shape of your room. As well as windows and doors.
