Why does your meeting room audio sound terrible? The four causes and how to fix each one, without replacing all the hardware.
Chris Gore \ Updated 2026
Remote participants cannot hear properly. Voices echo. Background noise bleeds through constantly. The quiet person at the end of the table is inaudible. And someone is always asking everyone to repeat themselves.
Bad meeting room audio is the single most common complaint in hybrid working and it almost never gets fixed properly. Most organisations either ignore it, blame the software platform or spend money on new hardware that does not solve the underlying problem. This guide covers the four real causes and what to actually do about each one.
The Four Causes of Bad Meeting Room Audio
Cause one: echo and reverberation
Hard surfaces are the most common cause of poor audio in meeting rooms. Glass walls, marble tables, wooden floors, exposed ceilings, all of them reflect sound. What the microphone picks up is not just the speaker's voice. It is the speaker's voice plus a fraction-of-a-second reflection of the same voice bouncing off every surface in the room. Remote participants hear this as a hollow, roomy sound that makes voices harder to understand over longer calls.
The physical fix is acoustic treatment, panels on walls or ceiling, soft furnishings, carpet. The electronic fix is a DSP with acoustic echo cancellation configured to the specific room. The best results come from both.
Cause two: no DSP processing
A microphone without any digital signal processing sends a raw audio signal to the call. Every air conditioning rumble, keyboard tap, paper rustle and chair scrape is transmitted faithfully alongside the speech. A DSP, digital signal processor, sits between the microphone and the call and processes the signal in real time: removing echo, filtering noise, balancing levels across multiple microphones and gating inactive channels. Without it, even a high-quality microphone sounds amateurish. Our DSP guide covers this in detail.
Cause three: wrong microphone placement
A table microphone surrounded by water bottles, coffee cups and laptops has its pickup pattern disrupted. A ceiling microphone positioned in the wrong zone misses participants at one end of the table entirely. A video bar mounted on the wrong wall creates a pickup dead zone directly opposite. Microphone placement is one of the highest-impact decisions in any room audio setup and it is one of the most commonly done by guesswork rather than design.
The gold standard for boardrooms is a ceiling microphone array positioned to provide even coverage across every seat. Shure's MXA series and Biamp ceiling arrays are the most commonly deployed options in UK professional environments. For a deep dive into microphone options, read our guide on what good boardroom microphone audio looks like.
Cause four: inadequate speakers
Thin speakers cannot fill a room. When remote participants sound like they are calling from a laptop in the corner, the problem is usually the room speakers rather than the call quality. Meeting room speakers need to be sized to the room, positioned correctly and matched to the DSP output. A speaker that is too small for the space forces participants to strain to hear, and that physical effort is enough to reduce engagement in longer calls.

How to Fix Each One
Fix echo: acoustic treatment plus DSP
Adding even a small amount of acoustic absorption to a hard-surface room makes a significant difference. Wall panels, a ceiling baffle, carpet under the table, all reduce the reflection that causes echo. Combine this with a DSP configured with acoustic echo cancellation tuned to the room and the improvement is immediate and substantial.
Fix no DSP: install proper processing
The Shure IntelliMix P300 is the most commonly installed dedicated DSP for UK meeting rooms. It pairs with Shure ceiling microphones and provides the full IntelliMix processing suite, echo cancellation, noise reduction, automatic mixing, automatic gain control. For rooms using an all-in-one video bar, check whether the bar already includes built-in DSP. Most modern Logitech, Neat and Yealink bars do. Read our full DSP guide for more.
Fix mic placement: reposition or replace
Before buying new microphones, try repositioning what is already in the room. Move the table mic to the centre of the table and away from any obstacles. Check that a ceiling mic is positioned over the centre of the seated area, not offset to one side. If repositioning does not solve the problem, a ceiling array is the most reliable long-term solution for rooms with ten or more participants.
Fix speakers: match speaker to room
Purpose-built meeting room speakers sized for the room dimensions make a bigger difference than most people expect. QSC, Biamp and Yamaha all produce meeting room speakers designed specifically for speech intelligibility. The speaker output needs to be matched to the DSP gain structure, another reason commissioning matters. A speaker installed without DSP tuning will either be too loud, too quiet or feedback in certain room positions.

When meeting room audio is done well, it becomes invisible. Nobody notices the audio because there is nothing to notice. Remote participants hear everyone in the room at a consistent level. The background noise of the office does not bleed through. The echo is absent. The quiet person at the far end of the table is as audible as the person nearest the microphone.
This is what SPOR Group delivers on every audio installation. Every microphone position is designed for the room. Every DSP setting is configured and tested before handover. Every room is backed by SPORTrack monitoring so audio performance is tracked after installation, not just at sign-off.

Frequently Asked Questions
Why does my meeting room audio have echo?
Echo in a meeting room is almost always caused by hard reflective surfaces — glass, marble, wood and bare walls bounce sound around the room. The fix is acoustic treatment to absorb reflections and a DSP with acoustic echo cancellation configured to the specific room.
What is DSP and do I need it for my meeting room?
A digital signal processor sits between the microphone and the call, applying echo cancellation, noise reduction, automatic mixing and gain control in real time. Any meeting room used seriously for hybrid calls needs some form of DSP processing, whether in a dedicated unit or built into the video bar.
Why can remote participants not hear people clearly in my meeting room?
The most common causes are wrong microphone placement, missing DSP processing, echo from hard surfaces, or speakers that are too small for the room. Check the microphone position first — it is the most common cause and the cheapest to fix.
What is the best microphone for a medium-sized meeting room?
For a medium meeting room of six to ten people, a ceiling microphone array from Shure or a high-quality table mic with DSP processing provides the most consistent coverage. For a smaller room using a video bar, the bar's integrated microphones are adequate if the bar includes proper built-in processing.
Does a video bar include audio processing?
Most modern video bars from Logitech, Neat and Yealink include built-in DSP processing — echo cancellation, noise reduction and automatic gain control. For small to medium rooms, this is typically sufficient. For larger rooms with separate ceiling microphones and speakers, a dedicated DSP unit is almost always necessary.
