Open-plan rooms over 40 square metres swallow soft furnishings fast, and bare walls plus hard flooring turn every conversation into an echo chamber. This guide ranks the acoustic wood panel options for large open-plan spaces and tells you which format solves which layout problem.
- Natural Oak Wooden Wall Panels win overall for acoustic panels open plan large rooms needing full-wall coverage.
- Hexagon Acoustic Panels in Grey Walnut with Grey Felt suit large office feature walls where pattern reads from a distance.
- Smoked Oak Wooden Wall Panels work best for dark accent zones in tall commercial rooms.
- Rustic Oak Premium 3-Sided Veneer suits textured, high-ceiling conversions with exposed structure.
- Hexagon panels carry an NRC rating of 0.75, the same absorption figure across every finish in the range.
Why this matters
A large open-plan room has more hard surface per person than a small enclosed office, so reverberation time stretches and speech clarity drops even when the room isn't loud. Slat panels and hexagon acoustic panels both use a felt backing to cut that reverberation, but the geometry changes how much wall you need to treat and how the room reads visually once it's done.
Akuwood Panel supplies both the slat-format wooden wall panels (240 cm and 300 cm lengths) and the hexagon acoustic panel range, all built on a 3-sided real wood veneer face with acoustic felt behind it. In a large open-plan room the choice usually comes down to whether you're breaking up a long run of wall or building a feature panel that reads as a single visual anchor.
What makes the best acoustic panel for a large open-plan room
- Absorption rating — the NRC figure behind the veneer, not just the wood finish on top.
- Panel format — long slat runs cover distance fast; hexagons build density on a single feature wall.
- Length options — 240 cm and 300 cm formats matter more in large rooms where floor-to-ceiling runs are common.
- Grain consistency — real wood veneer needs to match across a long wall, not just look good in one photo.
- Zoning function — whether the panel can double as a soft room divider in an open-plan layout.
- Fixing method — large rooms mean more linear metres of wall, so installation speed matters.

1. Natural Oak Wooden Wall Panels: best acoustic panel for open-plan living and dining zones
Natural Oak Wooden Wall Panels are the standard slat-format panel in the Akuwood Panel range, built with a 3-sided real wood veneer face and an acoustic felt backing. In a large open-plan living-dining room, running these floor-to-ceiling along one long wall treats the biggest reflective surface without touching the rest of the room.
Natural Oak Wooden Wall Panels pros:
- Available in both 240 cm and 300 cm lengths, useful for standard and higher ceilings
- Light finish keeps a big room from feeling closed in
- Slat format covers linear wall distance efficiently
Natural Oak Wooden Wall Panels cons:
- A lighter finish shows scuffs faster than darker tones
- Slat lines emphasise any wall that isn't perfectly flat
Best for: open-plan living and dining rooms where the goal is warmth plus echo control. Verdict: Buy.
2. Hexagon Acoustic Panel, Grey Walnut with Grey Felt: best acoustic panel for large office feature walls
The Hexagon Acoustic Panel in Grey Walnut with Grey Felt carries the same 0.75 NRC rating as the rest of the hexagon range, built on a real wood veneer finish designed to hold up over years of use. In a large open-plan office, a hexagon wall reads as a deliberate design feature rather than a patch of acoustic treatment, which matters when the wall faces a reception area or a boardroom glass line.
Hexagon Acoustic Panel pros:
- 0.75 NRC rating suited to speech-heavy open-plan offices
- Geometric pattern reads clearly from across a large floor plate
- Grey felt backing pairs with neutral commercial colour schemes
Hexagon Acoustic Panel cons:
- Individual hexagon units take longer to fit than full-length slats over a large wall
- Pattern-heavy finish isn't right for rooms that need a plainer backdrop
Best for: open-plan offices and reception walls where the panel doubles as a design statement. Verdict: Buy.
3. Grey Oak Wooden Wall Panels: best acoustic panel for minimalist open-plan workspaces
Grey Oak Wooden Wall Panels sit in the same slat format as Natural Oak, but the cooler tone suits open-plan workspaces that lean neutral rather than warm. In a co-working floor or a shared studio, grey reads calmer against grey carpet tile and exposed steel than a golden oak tone does.
Grey Oak Wooden Wall Panels pros:
- Cool tone matches neutral commercial interiors
- Same slat format and felt backing as the rest of the wooden wall panel range
- Works alongside black or dark grey fixtures without clashing
Grey Oak Wooden Wall Panels cons:
- Can read as cold in a room without other warm materials
- Less contrast against white walls than darker finishes
Best for: minimalist open-plan offices and studios. Verdict: Buy for neutral fit-outs.
4. Smoked Oak Wooden Wall Panels: best acoustic panel for dark accent zones in tall commercial rooms
Smoked Oak Wooden Wall Panels bring a deep, near-black tone that anchors a large room instead of blending into it. In a tall open-plan space — a converted warehouse floor or a double-height lounge — a dark wall gives the eye a fixed point, which matters when every other surface is pale concrete or plaster.
Smoked Oak Wooden Wall Panels pros:
- Deep tone works as a visual anchor in tall, open rooms
- Same 3-sided veneer and felt backing as the lighter finishes
- Hides less light staining than pale finishes over years of use
Smoked Oak Wooden Wall Panels cons:
- Shows dust and surface marks more visibly than mid-tone finishes
- Can make an already dark room feel heavier if overused
Best for: dark accent zones in tall or double-height commercial rooms. Verdict: Buy for accent walls, not full-room coverage.
5. Rustic Oak Premium 3-Sided Veneer: best acoustic panel for high-ceiling, textured large spaces
Rustic Oak Premium 3-Sided Veneer panels carry a heavier grain texture than the standard oak finishes, which reads better across a large distance than a smooth finish does. Barn conversions, high-ceiling extensions, and industrial-style open-plan rooms with exposed beams suit this texture because the room already has visual weight to match.
Rustic Oak Premium pros:
- Heavier grain texture holds up visually at distance in large rooms
- 3-sided veneer construction matches the rest of the wooden wall panel line
- Suits rooms with existing exposed timber or brick
Rustic Oak Premium cons:
- Busier grain can overwhelm a smaller side room
- Texture needs a room with enough scale to carry it
Best for: high-ceiling conversions and industrial-style open-plan spaces. Verdict: Buy for textured, large-scale rooms; skip for tight spaces.
How this ranking was built
Each panel was scored against the six criteria above: absorption rating, format, length options, grain consistency, zoning function, and fixing method. Natural Oak Wooden Wall Panels rank first because the 240/300 cm format covers a large open-plan wall efficiently while keeping the room bright; the hexagon range ranks second for rooms where the wall itself needs to be a design feature rather than a background surface.
Which acoustic panel should you choose for a large open-plan room?
If you're treating one long wall in a living-dining open-plan space, Natural Oak Wooden Wall Panels are the default pick for 2026 — the 300 cm length covers floor-to-ceiling runs without extra joints. If the wall in question is an office feature wall facing a reception desk or glass partition, the Hexagon Acoustic Panel in Grey Walnut with Grey Felt carries the same 0.75 NRC rating with a pattern that reads better from across a large floor plate. For anyone undecided, start with the slat format — it's the faster install across the most square metres.
FAQ
What's the best acoustic panel for a large open-plan room?
Natural Oak Wooden Wall Panels are the best overall pick for acoustic panels open plan large rooms in 2026, thanks to the 240 cm and 300 cm length options that cover long wall runs without extra joints. Hexagon Acoustic Panels suit large office feature walls where pattern matters more than speed of coverage.
How many acoustic panels do I need for a big open-plan space?
Coverage depends on the room's total wall area and how much reverberation you're trying to cut, so measure the specific wall run before ordering. Treating the longest single reflective wall first usually delivers the biggest audible change in a large room.
Do wood slat panels work as well as foam panels in large rooms?
Wood slat panels with a felt backing, like the Natural Oak and Grey Oak Wooden Wall Panels, provide absorption through the felt layer while keeping a finished wood face — foam panels absorb well but don't double as a visible interior finish. In a large open-plan room where the wall is on display, the wood veneer format does both jobs at once.
Is hexagon or slat panelling better for open-plan offices?
Hexagon Acoustic Panels suit a single feature wall where the geometric pattern needs to read from across the floor, while slat-format Wooden Wall Panels suit long runs where speed of coverage matters more than pattern. Most large open-plan offices use slats for the bulk of the wall and hexagons for one accent wall.
How much wall coverage reduces echo in a large room?
There's no single percentage that fits every room, since ceiling height, flooring, and furniture density all change how sound behaves. Treating the longest bare wall first, rather than spreading panels thinly across several walls, tends to give the most noticeable drop in echo.
Can acoustic wood panels be used to zone an open-plan area without full walls?
Yes — a run of Wooden Wall Panels along a single section of wall or a half-height divider can mark a zone boundary in an open-plan layout while still absorbing sound. This works particularly well between a living zone and a dining zone in one large room.
What NRC rating should I look for in acoustic panels for big rooms?
The Hexagon Acoustic Panel range carries a 0.75 NRC rating, which is a solid mid-to-high absorption figure for a decorative wood-faced panel. In a large open-plan room, pairing that rating with enough covered wall area matters more than chasing a marginally higher number on paper.
Do I need 240 cm or 300 cm panels for a large open-plan room?
300 cm panels suit rooms with standard-to-tall ceilings where a single panel can run floor to ceiling without a joint, while 240 cm suits more standard ceiling heights. Measuring the actual wall height before ordering avoids an unnecessary cut line partway up the wall.
One last thing
The felt backing behind the veneer, not the visible wood grain, is what drives the 0.75 NRC rating on the hexagon range — two panels can look completely different on the wall and perform identically for absorption. When you're speccing a large open-plan room, pick the finish for the room's look first and trust that the felt layer is doing the acoustic work underneath.
