What Is Acoustic Treatment and Does Your Meeting Room Need It?
Acoustic treatment stops echo and background noise ruining video calls. Here is what it involves and whether your meeting room actually needs it.
Chris Gore | Updated 2026
Acoustic treatment is one of the most overlooked parts of a meeting room fit-out, usually because it is invisible right up until a video call sounds terrible. A room can have the best camera and display available and still leave remote participants straining to hear, because nobody addressed how sound behaves inside the space itself. We have covered the wider picture in our piece on what an hour of broken boardroom AV actually costs, and acoustic treatment is often the missing piece behind audio complaints that never get properly diagnosed.
What Acoustic Treatment Actually Is
Acoustic treatment refers to materials and design choices that control how sound reflects and travels inside a room. Hard, flat surfaces, glass walls, bare plaster and polished floors, all bounce sound around a space, creating echo and making it harder for microphones to pick up a clear voice. Acoustic treatment softens or breaks up those reflections, so sound behaves more predictably, both for people in the room and for anyone joining remotely.
How to Tell If Your Meeting Room Needs Acoustic Treatment
The Clap Test
Stand in the middle of an empty meeting room and clap once, sharply. If the sound rings out or echoes noticeably rather than stopping almost immediately, the room is reflecting far more sound than it should. This simple test catches most rooms that would benefit from acoustic treatment without needing any equipment at all.
What Remote Participants Are Actually Hearing
A room can sound perfectly fine to the people sitting inside it while sounding hollow, echoey or muffled to anyone joining by video call, because a meeting room microphone picks up reflected sound in a way the human ear tends to filter out automatically. Asking remote participants directly how a room sounds, rather than assuming it is fine because nobody in the room has complained, is usually the fastest way to spot a problem.
Types of Acoustic Treatment for Meeting Rooms
Acoustic Panels
Fabric wrapped acoustic panels mounted to walls are the most common form of acoustic treatment, absorbing sound rather than reflecting it. They come in a range of finishes that can match existing interior design, so acoustic treatment does not have to look like an afterthought bolted onto a finished room.
Ceiling Baffles and Clouds
In rooms with high or exposed ceilings, suspended acoustic baffles or clouds address reflections that wall panels alone cannot reach. These are particularly useful in converted industrial spaces or rooms with exposed structural ceilings, where hard surfaces overhead contribute heavily to echo.
Soft Furnishings and Carpet
Not every acoustic improvement requires specialist panels. Carpet instead of hard flooring, upholstered chairs instead of moulded plastic, and curtains or fabric screens all absorb sound and reduce reflections, and are often enough on their own in smaller meeting rooms.
Acoustic Treatment Versus a Better Microphone
It is tempting to solve a bad sounding room by buying a more expensive microphone rather than addressing the room itself, but a better microphone still has to work with the sound the room is producing. A high quality microphone in a room full of hard reflective surfaces will pick up the echo just as clearly as it picks up someone speaking, simply at a higher resolution. Acoustic treatment addresses the actual cause, while upgrading the microphone alone only masks the symptom, often at a higher cost than the treatment would have been in the first place.
What Acoustic Treatment Costs
Basic acoustic panelling for a standard meeting room typically costs a few hundred pounds per wall, rising for larger rooms, ceiling baffles or bespoke finishes matched to existing interior design. It is a relatively small addition against the cost of a full AV installation, and one that is far cheaper to plan in from the outset than to retrofit once a room is already in daily use. Our AV snagging list covers wider installation checks if acoustic treatment is being planned alongside a larger fit-out.

Frequently Asked Questions
What is acoustic treatment in a meeting room?
Acoustic treatment is any material or design choice that controls how sound reflects inside a room, reducing echo and improving how clearly a microphone picks up voices for anyone joining a call remotely.
Does every meeting room need acoustic treatment?
Not every room, but any room with hard, flat surfaces such as glass, bare plaster or polished floors is a strong candidate. A simple clap test in an empty room is usually enough to tell whether acoustic treatment is needed.
How much does acoustic treatment for a meeting room cost?
Basic panelling typically costs a few hundred pounds per wall, with cost rising for larger rooms, ceiling baffles or bespoke finishes. It is a small addition compared to the overall cost of a meeting room AV installation.
Can soft furnishings replace proper acoustic treatment?
In smaller rooms, carpet, upholstered furniture and curtains can meaningfully reduce echo on their own. Larger or harder surfaced rooms usually still benefit from dedicated acoustic panels or ceiling baffles alongside them.
Will a better microphone fix a room without acoustic treatment?
Not on its own. A higher quality microphone still picks up whatever the room is reflecting, so it can make an echo problem more noticeable rather than less. Acoustic treatment addresses the actual cause instead of masking it.
