Every office has one: the boardroom where every meeting starts with five minutes of "Can you hear me now?", "You're on mute", and someone leaning into the speakerphone. Bad boardroom audio is more than an annoyance — it wastes meeting time, makes your company look unprofessional to clients and remote colleagues, and quietly pushes people back to their desks. Most of the problems we are called out to fix in Dubai offices come down to a handful of faults, and most are fixable without replacing the whole system.
1. Remote participants can't hear the room
This is the single most common complaint, and the usual cause is the microphone, not the internet connection. A single speakerphone or the microphone built into a webcam can only pick up voices clearly within about two to three metres. In a boardroom seating ten or twelve people, anyone at the far end of the table sounds distant, muffled, or drops out entirely. The fix is coverage, not volume: ceiling microphones or a set of table microphones spaced along the table so that nobody is more than about two metres from a mic. For daily hybrid meetings, a proper microphone array is the best-value upgrade you can make.
2. The room hears itself: echo and feedback
Echo happens when the room's speakers feed back into the microphones — remote participants hear their own voice a fraction of a second late, and in bad cases the room produces a loud squeal. The usual culprits are speakers and microphones placed too close together, or a conferencing setup with no acoustic echo cancellation. Purpose-built meeting-room audio equipment handles echo cancellation in hardware, and a digital signal processor (DSP) can tune it for your specific room.
3. One person is loud, the next is inaudible
Uneven levels are a coverage problem. A microphone on the table picks up the person next to it at full volume and the person four seats away at a whisper. Ceiling microphone arrays and beamforming microphones are designed for exactly this: they listen in several directions at once and balance the levels automatically. If a full array is beyond budget, even moving to two or three table microphones, spaced evenly, makes a noticeable difference. And a microphone two metres away cannot do the job of one on the table in front of the speaker.
4. Humming, buzzing and crackling
A constant hum or buzz usually points to the cabling, not the equipment. Long unbalanced analogue cable runs next to power cables pick up interference; loose connectors crackle when the table is bumped. The fix is proper shielded cabling, kept away from mains runs, with connectors checked and reseated. If the noise only appears when a laptop is plugged into mains power, a ground-loop isolator on the audio line is the standard answer.
5. The wrong device is selected
We see this constantly: the meeting starts on the room's speakers and microphones, but Teams or Zoom has defaulted to the laptop's own mic and speakers, or to a display that has no microphone at all. The result is a meeting that technically works — and nobody can hear anything useful. Set the room's audio devices as the default in the conferencing app, and check the device selection as part of your meeting-room start-up routine. If the room has a dedicated Teams Room or Zoom Room system, lock the settings down so a visiting laptop cannot change them.
6. Audio drops when sharing a screen
When audio cuts out the moment someone shares a presentation, the cause is usually the display connection. A laptop connected by HDMI to the room display can silently switch its audio output to the display's speakers, which may be tiny, muted, or absent altogether. Keep the audio path separate from the video path where possible, or configure the room system so the speakers stay on the conferencing audio regardless of what is on screen.
A quick diagnostic checklist
- Nobody remote can hear the room: check microphone coverage and device selection first.
- Echo or squealing: check speaker-to-microphone distance and echo cancellation.
- Uneven voices: add microphone coverage; check for beamforming or DSP levelling.
- Hum or buzz: check cable runs, connectors and ground loops.
- Audio vanishes on screen share: check where the laptop is sending its audio.
- Everything works sometimes: suspect loose connections or a device that resets its settings — document the working configuration and lock it down.
When to call in a specialist
If the same problem returns after you have checked the obvious causes, the issue is usually in the design rather than a single faulty part: microphones in the wrong place, speakers fighting the room, or a system that was never properly tuned after installation. A proper boardroom audio setup is designed for the room — its size, its table layout, and how many people join remotely — not bought off the shelf.
Good boardroom audio should be invisible: people sit down, the meeting starts, and everyone — in the room and on the call — hears everyone else. If your boardroom is not doing that yet, the fix is usually smaller than you think. Request a quote, call us on (04) 359 4874, or message us on WhatsApp at +971 52 562 1946 for a free site survey — we will test your boardroom audio, find the fault, and quote the fix, with no obligation.
