You upgraded the camera and the microphone, but the problem was never technology
Somewhere in your office is a glass box that everyone slightly dreads. Voices ring in it. Video calls sound like they are happening in a stairwell. The people on the far end keep asking someone to repeat that, please.
The standard response is to blame the technology, and offices spend accordingly: better microphones, smarter speakers, echo-cancelling software. The gear improves, the room still sounds hollow, and the far end still strains.
The actual problem costs less to fix than the average conference camera, yet most offices never think of it. The room itself is untreated, and no microphone can fix a room.
Why meeting rooms echo
Meeting rooms concentrate every reflective surface an interior can have into the smallest possible space. Glass walls, often on two or more sides. A hard ceiling. A large laminate table that acts as a mirror for every voice around it. A whiteboard or screen on whatever wall the glass spared.
Sound in a room like this has nowhere to die. Each word reflects between the glass, the table, and the ceiling several times before fading, and the room adds a hollow, ringing quality that everyone recognises and nobody enjoys. Acousticians measure it as reverberation time, and small glass rooms are often the worst performers per cubic metre in the entire building.
The irony is that meeting rooms are the one space in an office that is built specifically for speech. The fitout gives the best acoustic conditions to the corridors and the worst to the room where clarity matters most.
The reason video calls suffer most from echo
Hybrid work turned a comfort problem into a performance problem.
In the room, human hearing does a remarkable job of filtering reflections. Your brain knows the room, adjusts, and follows the conversation, at the cost of some listening effort. A microphone has no such talent. It captures the direct voice plus every reflection at full value, and sends the whole muddle down the line. This is why the far end of a call suffers more than anyone in the room, and why they keep asking people to repeat things the room heard fine.
Echo-cancelling software helps with the electronic loop, but it cannot remove the room’s own reverberation from a voice before the microphone hears it. Once the reflections are in the signal, they are in the meeting. The only place to fix it is on the walls and ceiling, before the sound reaches the microphone at all.
The quick fix to meeting room echo
Meeting rooms are the most satisfying spaces to address in commercial acoustics. They’re small enough that a modest amount of treatment transforms them completely.
Treat one or two key surfaces
A small room does not need every surface covered. Absorption on the rear wall (the one facing the screen), plus either the ceiling or one side wall typically takes a glass box from hollow to composed. The Calando acoustic panel handles walls, and Calando acoustic ceiling tiles cover the lid where glass leaves no wall to work with.
Make the treatment part of the room
This is where meeting rooms get enjoyable. The Custom Calando acoustic panel can carry brand graphics, photography or artwork, turning the acoustic fix into the feature wall behind the screen – the one every external caller sees for the length of every meeting. Plenty of clients discover their acoustic upgrade doubles as their best branding surface. Where a softer, upholstered look suits the space, Calando acoustic fabric offers a stretched finish, and boardrooms often choose Calando acoustic timber for a warmer, architectural character.
Mind the speech going the other way
Echo is the noisy half of the meeting room problem. The quiet half is privacy. Conversations that ring inside a hard room also project out of it, through glass and over partitions, which matters when the meeting is a performance review or a client negotiation. Absorption inside the room reduces the energy escaping it, and door seals close the most common leak. If your meeting rooms need genuine confidentiality, please mention it, because it shapes our design.
What it takes to address meeting room echo
A typical meeting room acoustic solution is assessed in minutes, designed in days, and installed in a few hours, usually after work on a weekday or during a quiet Friday afternoon. There is no construction, and the room hosts meetings again the same day. The change is immediate and oddly personal. People stop leaning towards the microphone. The far end stops asking for repeats. And the room everyone avoided quietly becomes the room everyone books!
For offices with several rooms, treating the worst two or three first delivers most of the benefit, and the consistent panel design across rooms reads as a deliberate fitout decision rather than a patch.
Talk to the experts in treating meeting room echo
Meeting room echo is a room problem wearing a technology costume, which is why the gear upgrades never quite work. Put absorption on one or two of the right surfaces, let the panels carry your brand while they are at it, and both halves of every conversation – in the room and on the far end – finally hear what was actually said.
