Frequency & Acoustic Treatment
A no-nonsense guide to how sound behaves — and how Balanced Acoustics helps you control it.
How Sound Behaves in a Room
Sound is energy moving through air in waves. When those waves hit surfaces — walls, floors, ceilings, desks, windows — they react in predictable (but often frustrating) ways.
Understanding these reactions is the key to controlling your space.
Why Your Room Matters Most
People love to blame their gear for bad sound.
In reality, your room is the biggest factor in what you hear.
Even the best monitors, mics or headphones are at the mercy of the physics happening around you. Acoustic treatment isn’t a luxury add-on — it’s the foundation of accurate sound.
This page breaks it down clearly:
how sound reacts, why treatment works, and how you can build a room that finally tells the truth.
Reflection
where most problems start
Hard, flat surfaces bounce sound straight back toward you. These reflections interfere with the original signal and cause:
-
Flutter echo (that metallic “ping” when you clap)
-
Comb filtering (weird phasey hollow sound)
-
Harsh mids and highs
-
Mud in vocal recordings
-
Poor stereo imaging
Reflections create multiple “copies” of every sound, and your brain has to guess which one is the real one. Treatment makes that guesswork disappear.
Good absorption reduces echo, tightens mids and highs, and creates clarity.
Cheap thin foam barely touches the problem.
Absorption
Converting sound into heat
(tiny, controlled heat)
Proper acoustic panels absorb sound by forcing it through dense, porous material that slows the wave down and dissipates its energy.
The important factors are:
-
Panel thickness
-
Material density
-
Airflow resistivity
-
Mounting distance from the wall
Bass Frequencies
pressure waves that don’t care about your feelings
Low frequencies act differently from mids and highs. Instead of simple reflections, bass creates pressure patterns in the room.
This causes:
-
Standing waves
-
Room modes
-
Boomy corners
-
Bass dropouts (nulls)
-
Peaks that make your mixes lie to you
A 50Hz wave is about 7 metres long.
Small rooms simply can’t contain that without help.
That’s why proper bass traps — deep, high-density, corner-mounted traps — are the most important treatment you can add.
And yes, we design ours for real-world rooms, not theoretical sound labs.
Balanced Acoustics offers real QRD and skyline diffusers, the kind that are mathematically calculated — not just random timber blocks glued together.
Diffusion
organised chaos that keeps a room lively
Diffusers scatter sound waves in controlled patterns rather than absorbing them.
This preserves liveliness without creating harsh reflections.
Technically they:
-
Break up coherent reflections into micro reflections
-
Spread energy evenly around the room
-
Improve spaciousness
-
Prevent the “dead booth” effect
What Acoustic Treatment Actually Fixes
A treated room performs better in both the frequency domain and the time domain.
✔ Flatter frequency response
What you hear = what’s actually happening.
✔ Controlled decay times
No more low-end ringing or top-end smear.
✔ Better stereo imaging
Reflections aren’t blurring the left/right balance.
✔ Improved clarity
Vocals sound clean. Instruments sound real. Drums hit properly.
✔ Less ear fatigue
Great for long sessions, whether you mix, game, record, teach or produce.
The 3 Core Tools of Pro Treatment
Broadband Absorber Panels
For mids, highs, and early reflections.
Used for:
-
First reflection points
-
Behind monitors
-
Behind the listening position
-
Vocal recording
Depth + density = performance.
We build panels that actually perform, not decorative fabric boards.
Bass Traps
Corner-mounted, deep, high-density traps that stabilise the low end.
They:
-
Flatten bass response
-
Reduce boomy corners
-
Eliminate nulls
-
Make mixes translate
The low end is where most rooms lie — and where Balanced Acoustics shines.
Diffusers
Used once absorption is under control to bring a natural, open feel back to the room.
Ideal for:
-
Back walls
-
Rehearsal rooms
-
Large vocal spaces
-
Rooms that risk sounding “dead”
Diffusion makes a space feel bigger and more musical.
