A few years ago, I was called in to assess the boardroom of a large global multinational headquartered in Dubai. This was no ordinary room, it was the space where global CEO and leadership team convened, and it had been outfitted accordingly. High-end ceiling microphones. Enterprise-grade DSP. Quality loudspeakers. A UC platform from well-known brands in the industry. The system was premium.

And yet every time the CEO connected with his global leadership team, the meeting stalled. Remote participants constantly asked him to repeat himself. The team in Dubai, in turn, struggled to make out words from the far end. For a boardroom commanding that level of investment, it was a frustrating and embarrassing situation for the participants.

The organisation did what most do in such circumstances, they called their UC integrator. Microphones were recalibrated. DSP parameters were adjusted. Configurations were reviewed. Hardware was rechecked. Nothing changed.

When we stepped in to conduct a proper technical analysis, the culprit was not the signal. It was the space. The room was highly reverberant, lined with glass and finished in hard stone, beautiful materials, acoustically catastrophic. By treating the room’s acoustics rather than continuing to fidget with boxes on the wall, we finally resolved the issue. Today, that CEO communicates effortlessly with his global teams. Same equipment. Completely different experience.

This story is not unique. It plays out in conference rooms across the world, every single day.

The Equipment Trap

This assumption is wrong, and it is costing organisations enormous sums while leaving their people with meeting experiences that are exhausting, unproductive, and demoralising. If the acoustic environment is flawed, electronics can only do so much.

The reality is that a microphone does not capture just speech. It captures speech plus the acoustic signature of the room it occupies. In a highly reverberant space, sound bounces off the ceiling, reflects from glass walls, ricochets off hard tabletops, and rebounds from polished floors, each of these reflections arriving at the microphone at slightly different times. The result is overlapping versions of the original speech, smeared across time in a way that no amount of digital processing can fully untangle.

The microphone faithfully reproduces all of it. Remote participants receive not a clean signal but a muddy, echoing version of the conversation, forcing their brains to work overtime to extract meaning from the acoustic fog. Intelligibility drops. Even at adequate volume levels, clarity suffers. And increasing gain does not help, it simply amplifies both the direct sound and its many reflections, making everything messier. This is where many organisations find themselves trapped in a frustrating and expensive cycle: poor clarity leads to calls for better microphones; better microphones pick up even more of the room’s problems; complaints about echo prompt suggestions of better speakers or additional processing.

Each “solution” addresses the symptoms while the underlying cause goes untreated.

When Electronics Cannot Save You

The AV industry has produced genuinely impressive digital signal processing technologies. Echo cancellation algorithms, beam forming microphone arrays, noise reduction filters, automatic gain control, these represent real engineering achievements, and they absolutely have their place in a well-designed system.

But they work best when refining minor acoustic imperfections, not compensating for fundamental room problems. Asking DSP to overcome severe reverberation is like asking photo editing software to correct a blurry photograph, you can improve it somewhat, but you cannot recover information that was never cleanly captured in the first place.

When sound bounces around a room for several hundred milliseconds, creating dense overlapping reflections, no algorithm can perfectly separate the direct signal from its many delayed copies. The processing can reduce the problem’s severity, but it cannot eliminate it. What you are left with is audio that sounds artificial and processed, still lacking the naturalness and clarity that proper acoustic treatment would deliver effortlessly.

The principle deserves to be stated plainly: electronics refine the signal; acoustics define the experience.

The Design Disconnect

Part of the problem lies in how modern workspaces are conceived and evaluated. Contemporary office design has increasingly favoured aesthetics that emphasise openness, natural light, and industrial materials. Floor-to-ceiling windows, polished concrete, exposed ceilings, minimal soft furnishings, and large hard-surface tables create environments that are visually striking and photograph beautifully for marketing materials.

From an acoustic standpoint, however, these design choices produce nearly the worst possible conditions for speech intelligibility. Hard, reflective surfaces do not absorb sound, they bounce it around the space, repeatedly. Large glass expanses function as near-perfect acoustic mirrors. Open ceilings eliminate one of the most effective locations for sound absorption. The result is a space that looks world-class but struggles fundamentally with the one task it is most frequently asked to perform: facilitating clear communication.

The consequences extend beyond frustration. Continuous mental filtering, separating speech from reverberation, distinguishing words from their own echoes, leads to genuine listener fatigue. Studies in psychoacoustics have demonstrated that this kind of cognitive load results in reduced comprehension, lower engagement, and shorter effective attention spans during meetings. People leave these calls feeling drained, often without understanding why. Collaboration quality suffers. Meetings run longer and achieve less. The human cost of poor acoustics is real, even if it rarely appears on a balance sheet.

Treating the Room, Not the Signal

The solution requires a fundamental shift in perspective. Acoustics must be treated not as an afterthought to be addressed if problems arise, but as an integral part of room design from the outset.

In practice, this means incorporating sound-absorptive materials in strategic locations. Acoustic ceiling tiles or suspended clouds can control overhead reflections. Fabric-wrapped panels on walls reduce lateral echoes. Thoughtful furniture selection, upholstered seating, soft goods, carpeting, contributes meaningfully to a more controlled acoustic environment. The goal is not to create an anechoic chamber where all reflections are eliminated; some acoustic liveliness is desirable for natural-sounding communication. The objective is to achieve appropriate reverberation time for the room’s size and intended use.

For existing spaces with persistent problems, acoustic treatment retrofits frequently deliver far better results than equipment upgrades. A modest investment in properly specified and positioned acoustic panels can outperform tens of thousands of dollars’ worth of premium microphones and speakers installed in an untreated room. We demonstrated exactly this in that Dubai boardroom. The equipment was never the problem. The room was.

Before selecting microphones, speakers, or processing hardware for any space, evaluate the acoustic environment those components will operate within. A modest AV system in a properly treated room will consistently outperform a premium system in an acoustically problematic one. The room is not simply a container for equipment, it is an integral component of the audio system itself, and arguably the most important one.

A Different Way of Thinking

What the AV industry needs is not more sophisticated signal processing — though that will certainly continue to improve, but it needs a cultural shift, a willingness to see the room as part of the system, not separate from it.

The most forward-thinking integrators and consultants in this space are already making that shift. Rather than arriving on a job with a catalogue of hardware and a configuration checklist, they begin with the room — its dimensions, its materials, its reverberation characteristics, its purpose. They treat acoustics as the foundation on which everything else is built, because that is precisely what it is.

The next time you are planning a conference room installation or troubleshooting an audio quality complaint, resist the reflex to reach for the spec sheet. Walk into the room. Clap your hands.
