Hybrid meetings fail on audio long before they fail on video. Remote participants hear a distant wash of room noise, cannot tell who is speaking, and stop contributing. The fix is microphone placement plus a discipline about speaking one at a time.
The core problem
A single conference-room microphone captures everyone at a different distance. The person nearest sounds loud, the person at the far end sounds distant, and the remote participant hears the room rather than the discussion.
- One microphone per two seats is the practical minimum
- Directional microphones reduce room pickup
- The chair controls turn-taking
Placement that works in a real room
Put a microphone in the middle of each side of the table, not at one end. If the room is long, two microphones beat one. Avoid placing them under air-conditioning vents, which produce a constant low-frequency rumble that no filter removes cleanly.
| Room size | Microphones | Note |
|---|---|---|
| Up to 6 seats | 1-2 | Centred on the table |
| 7-12 seats | 2-3 | One per side |
| Above 12 | 4+ | Or a ceiling array |
Turn-taking discipline
The chair names the speaker before they talk. Remote participants cannot see who is about to speak, so without naming, two people talk over each other and neither is intelligible. This is a process fix, not a technical one.
- Chair names the speaker
- One person talks at a time
- Remote participants get priority in the queue
The remote side
Remote attendees should use headphones and a close microphone. A laptop microphone in a home office picks up echo from the room speakers and re-injects it into the meeting. The OBS audio routing guide covers the filter order that keeps speech clean when several sources are mixed.
Recording the minutes
Record the meeting with consent and note the timestamps of decisions. A clear audio recording replaces most of the minute-taking burden, but only if the microphones were placed correctly in the first place.
Frequently Asked Questions
Do we need a ceiling array?
Only above about twelve seats. Below that, table microphones are cheaper and easier to troubleshoot.
Why does the far end of the table sound distant?
Distance and inverse-square falloff. Adding a second microphone fixes it better than raising gain.
Should remote participants be on video?
Video helps but audio matters more. A remote attendee with good audio contributes more than one with video and poor sound.
How do we handle side conversations?
Mute the room microphones during breaks. Side conversations are the main source of unusable recordings.
