If you’ve ever sat down to focus in an open-plan office and found yourself unable to tune out the phone call two desks away, you already know the problem this guide is about.
Noise is the number one complaint we hear from clients when working on commercial interior design projects. And it’s usually one of the first questions that comes up when a company starts planning a new space: How do we keep this from being loud?
At TNT Commercial, we spend a lot of time thinking about this, because we specify and install the acoustic furniture (the pods, panels and screens) that make offices livable and easy to work in.
What we’ve learned, project after project, is that there’s rarely one fix. A few panels on a wall won’t solve a noise problem if the layout itself is working against you. Real acoustic comfort comes from understanding a handful of different tools and using them together in the right places.
That’s what this guide walks through:
- Four layers of acoustic control.
- Specific furniture solutions that address each one.
- How the right approach changes depending on the kind of space you’re designing.
Why Office Acoustics Matter More Than Ever
Acoustic-first design is one of the top commercial furniture trends now. And for a good reason.
Open-plan layouts are still the default for most commercial tenants, across nearly every industry. And noise is, consistently, their biggest weakness.
The Leesman Index, a workplace research platform that has collected feedback from hundreds of thousands of employees worldwide, puts acoustics near the bottom of the list when people rate their own workspace. A large share of employees simply don’t feel their office supports focused, concentrated work. It’s the primary reason many people come into the office in the first place.
The shift back to in-person work has only made this harder. Offices that were designed years ago for a certain baseline hum now have to absorb more people in the same square footage. Plus a layer of noise that didn’t used to exist: video calls taken from open desks, headphones in, voices raised just slightly to compete with everything else. Put it all together and you’ll see that most offices are simply louder than they were built to handle.
For some businesses, a quiet space is more than just a comfort. Law firms and financial services companies have confidentiality obligations that make speech privacy a practical necessity. Healthcare-adjacent offices working under HIPAA face similar pressure.
And it’s telling that the WELL Building Standard, one of the most widely used frameworks for healthy building design, now includes acoustics as a core category. Acoustic planning has moved from something facilities deals with later to something that belongs in the fit-out specification from the planning stage.
The 4 Layers of Acoustic Control
Once you start looking at office acoustics closely, it helps to break the problem into layers. Here’s how we break them down:
| Layer | What it does | How it’s addressed |
|---|---|---|
| Absorb | Soaks up sound energy so it doesn’t bounce around the room | Upholstered furniture, carpet, acoustic panels, felt wall treatments, soft goods |
| Block | Interrupts sound as it travels from one person to another | Acoustic pods, high-partition screens, booth seating with enclosed backs and sides |
| Cover | Raises the background noise floor so nearby speech becomes harder to make out | Sound masking systems (ceiling speakers with low-level white or pink noise), usually an A/V specification, not furniture |
| Avoid | Prevents acoustic conflict by keeping loud and quiet zones apart | Space planning: locating noisy areas away from focus zones, positioning desks away from glass conference rooms, zoning by activity level |
A quick way to think about the difference between the first two: absorbing sound reduces how loud and echoey a room feels overall. Blocking sound doesn’t change the room’s overall volume. It just keeps specific noise from traveling as far. Both matter and they solve different problems.
Furniture speaks directly to the first two layers, Absorb and Block. If we’re brought in early enough (while the space is still being planned) we can also help with Avoid, since that’s really a layout decision more than a product one. Cover is a sound-masking system, usually specified separately by the building or an A/V contractor.
The best acoustic offices use all four layers together. If your space has beautiful panels on every wall (Absorb) but nothing separating your loudest zone from your quietest one (Block and Avoid), people are still going to be frustrated. Panels alone were never going to be enough.
Furniture Solutions: Pods, Screens, Panels & Soft Seating
Within the Absorb and Block layers, there are four main furniture tools worth knowing. Each one does a different job and each belongs in a different part of the office.
Acoustic pods
These are freestanding enclosures built for one to four people – the right spot for phone calls, video meetings, or heads-down focus work. Commercial pods are rated using NRC, the Noise Reduction Coefficient, which runs from 0 (no absorption at all) to 1.0 (full absorption). For a pod that’s going into a genuinely noisy environment, look for an NRC of 0.80 or higher.
It’s worth setting expectations here: pods don’t offer full soundproofing. What they do is reduce how far speech carries, which in most open-plan settings is the actual goal. Just enough separation that a call two pods over doesn’t derail someone’s concentration.
A rule of thumb we come back to often:
- One single-person pod per 8–10 desks.
- One meeting pod per team that regularly runs group calls.
Privacy screens and desk dividers
These are the mid-height panels (upholstered or with acoustic infill) that sit between neighboring workstations. They work at the Block layer, cutting down on direct speech transmission between the people sitting closest to each other. They won’t isolate anyone completely, but as part of a layered plan, they earn their place.
One thing worth checking before you buy commercial furniture: make sure the panel has genuine acoustic infill. A decorative panel that looks acoustic but isn’t will do almost nothing. Most commercial open-plan specs land somewhere between 16 and 24 inches above the desk surface.
Freestanding and wall-mounted acoustic panels
Fabric-wrapped panels, typically rated NRC 0.75–1.0, are usually the most cost-effective way to cut down reverb in an open space. They work best spread across two or three walls rather than clustered on one.
In rooms with high ceilings, ceiling baffles or suspended panels extend that same absorption vertically. They are useful anywhere wall panels alone aren’t reaching far enough. And panels don’t have to be purely functional: many manufacturers offer custom shapes, brand colors and printed surfaces, so they can double as a design element.
High-back lounge and booth seating
Upholstered high-back chairs and booths are not only good for ergonomics (see our ergonomic office furniture guide), they also create a kind of natural acoustic pocket for informal conversation, without the cost or footprint of a full pod.
They’re best suited to lounge and collaboration areas, where you don’t need complete enclosure but you do want some separation from the wider room. The upholstery itself also adds real absorption value in spaces where panels wouldn’t make sense.
A note from experience: the most common mistake we see with pods is tucking them into corners or against walls to keep them visually out of the way. It seems logical, but it backfires. People inside lose access to natural light and the space starts to feel more like a closet than a workspace, which quietly kills adoption. We generally recommend positioning pods perpendicular to the main open-plan area, so users can still see out and light comes in from the side.
Acoustic Design by Space Type
The right acoustic approach depends on how a space gets used. The same panel or pod that works beautifully in one area might do almost nothing in another. Here’s how we think about it, space by space:
| Space type | What makes it challenging | Where to focus |
|---|---|---|
| Open-plan workstations | Highest acoustic load in the office. Constant cross-desk conversation and calls |
|
| Conference rooms | Often over-treated inside, while the boundary with the open plan goes ignored | Treat the room itself, but don’t stop there. The wall or glass separating it from the open plan needs its own attention |
| Lounge & informal collaboration | Hard tables, glass, bare floors are materials that reflect rather than absorb |
|
| Reception / front-of-house | First impression space. Often finished in hard, reflective materials |
|
Materials That Absorb vs. Reflect Sound
Underneath all of this (pods, panels, screens) is a simpler question: what is the material itself actually doing to sound?
That’s measured by the NRC, the Noise Reduction Coefficient, a standardized rating defined under ASTM C423. It runs from 0, meaning a material reflects essentially all sound back into the room, to 1.0, meaning it absorbs nearly all of it. Most commercial acoustic products fall somewhere in the 0.5 to 0.95 range and that number should be listed right on the product spec sheet.
Here’s how the two ends of that scale break down in practice:
| High-absorption materials (NRC 0.65–1.0) | High-reflection materials (NRC 0.0–0.2) |
|---|---|
| Fabric upholstery | Glass |
| Acoustic foam | Polished concrete |
| Commercial carpet and carpet tile | Ceramic tile |
| Felt panels | Metal surfaces |
| Acoustic ceiling tile | Hard plastic |
| Fabric-wrapped acoustic panels | Stone |
A couple of things worth knowing about how these behave in the real world:
- Thicker, denser upholstery absorbs more than thin or tightly woven fabric, so not all “upholstered” furniture performs the same.
- Carpet significantly outperforms hard flooring at mid-to-high frequencies, which happens to be exactly the frequency range where human speech sits. That’s part of why carpet is often the single most cost-effective acoustic upgrade available.
- Offices with exposed concrete ceilings, polished floors and glass partitions are the hardest to treat with furniture alone. All that reflective surface area has to be offset by a much higher density of absorptive materials just to get the same result a softer-finished space would achieve with less.
What to look for when specifying
This is the part we’d encourage every business to pay attention to, because it’s where a lot of money gets spent on the wrong thing: always ask for the NRC rating before buying acoustic panels or pods.
Words like “sound-absorbing,” “acoustic,” or “noise-reducing” on packaging aren’t standardized terms. They don’t guarantee anything. A panel marketed as “acoustic” with an NRC of 0.35 will genuinely underperform in a busy open-plan office, even though the label sounds right.
As a working guideline:
- Panels in active open-plan zones → specify NRC 0.75 or higher.
- Pods in the same environment → specify NRC 0.80 or higher.
Every product we specify includes the NRC rating as its own line item in the documentation. If a vendor can’t produce that number, our view is simple: it shouldn’t be part of an acoustic specification.

Frequently Asked Questions
Do acoustic pods block sound completely?
No, acoustic pods reduce how far speech travels and how clearly it can be understood at a distance. They don’t create total silence or full soundproofing. For most open-plan offices, that’s the right level of control. The primary goal of acoustic furniture is to keep a call or conversation from being distracting to the people nearby.
How many acoustic pods does a typical office need?
A reasonable starting point is one single-person pod for every 8–10 desks, plus one larger meeting pod for each team that regularly runs group calls. That said, this is a guideline, not a fixed rule and the right number depends on how the team works, how much of the day is spent on calls and how much open floor space you’re working with.
What’s the difference between absorbing sound and blocking sound?
Absorbing reduces the overall echo and reverberation in a room, so the space feels quieter even at moderate conversation levels. Blocking doesn’t lower the room’s overall volume. It limits how far specific sounds travel, so a conversation at one desk doesn’t carry across the whole floor. Most offices need both, since they solve different problems.
Does furniture alone solve an office noise problem?
Furniture handles two of the four layers of acoustic control: Absorb and Block. For many offices, that’s most of the fix. But it works best alongside smart space planning, like keeping loud zones away from focus areas and in some cases a background sound-masking system. If the layout itself puts a noisy zone right next to a quiet one, furniture can only do so much.
Is it better to fix acoustics before or after moving into a new office?
Before, by a wide margin. Once furniture is installed and people are already working in the space, any real correction means disruption like moving things around, reordering, redoing work that’s already done. Building acoustic furniture into the initial specification costs less and produces a better result than trying to retrofit it into a space that’s already occupied.
