In short: Ceiling, table or wireless — we break down which microphone type suits your meeting room.
A good microphone in a conference room determines whether remote participants hear the room clearly, or fight echo, HVAC noise and swallowed sentence endings. In this guide we explain how to match a microphone type to the size and character of your meeting room, and what to watch for when planning the installation.
Three basic types of conference microphones
The vast majority of meeting room installations rely on one of three solutions — each with a different use case and a different cost-effectiveness threshold.
Ceiling microphones
Mounted in a suspended ceiling, completely invisible to meeting participants. They work well in rooms where aesthetics and a cable-free table matter. Modern models use beamforming technology — digitally "steering" sensitivity toward the person speaking, which significantly improves voice clarity while suppressing HVAC or corridor noise.
Table microphones (boundary / gooseneck)
The most universal solution — well suited to rooms for up to 10–12 people, where microphones are placed directly on the conference table. The downside is that the hardware is visible and cabling has to be routed across the tabletop, which some clients find less elegant than a ceiling-mounted solution.
Wireless microphones (lavalier / handheld)
Indispensable in training rooms, on stages and during presentations where the speaker moves around the room. They require an RF receiver and regular charging, but give complete freedom of movement.
What to consider when choosing
- Room size and shape — long, narrow rooms need a different microphone layout than square ones.
- Number of fixed seats — above 10–12 people, it is worth considering several microphone zones instead of a single central point.
- Room acoustics — rooms with a lot of glass and hard surfaces need extra reverberation control, otherwise even the best microphone will "catch" echo.
- Integration with the video conferencing platform — not every microphone works seamlessly with Microsoft Teams Rooms or Zoom Rooms — it is worth verifying this before purchase.
Rule of thumb: it is better to invest in fewer, well-placed microphones than in many cheap models scattered at random — the quality of the layout has a bigger impact on audio clarity than the specification of the hardware itself.
Acoustic feedback — how to avoid it
Feedback occurs when sound from the loudspeakers returns to the microphone and gets amplified in a loop. The most common causes are speakers placed too close to microphones and the absence of a DSP with echo cancellation. A professional installation always includes acoustic tuning after mounting — a step just as important as choosing the hardware itself.
Summary
Choosing a microphone for a conference room is a decision that should take into account the size of the room, how it is used, and integration with the rest of the AV system. In practice, the best results come from an acoustic audit of the room before buying equipment — it lets you choose a solution that actually solves the problem instead of masking it.
