How to Choose the Optimal Microphone for Conference Rooms?

Introduction

A conference room microphone is a crucial device for contemporary meetings that provides clear communication for attendees, both present and remote. Whether you’re holding a business meeting, virtual conference, or team collaboration, choosing the appropriate microphone can greatly affect audio quality and participation.

With various microphone choices accessible, it’s essential to grasp their categories, characteristics, and appropriateness for various conference arrangements. This guide will discuss the popular varieties of conference microphones, important aspects to think about when selecting one, and the top microphone options, featuring StarryHub, a smart meeting projector that includes an integrated microphone and built-in speaker.

1. Types of Conference Microphone

Conference microphones come in various designs for room setups, meeting formats, and audio needs. Below are some of the most commonly used conference microphones.

• Gooseneck Microphones

Gooseneck microphones are favored for panels, lecture stands, and conference rooms because of their flexible neck design. This design enables users to adjust the mic to the ideal angle, providing great speech clarity since the speaker stays near the microphone consistently. 

• Handheld Microphones

Handheld microphones are a flexible choice, particularly in interactive meetings, Q&A sessions, or panel discussions where various speakers must alternate speaking. They offer excellent adaptability, enabling the speaker to move around easily and share the microphone among various participants.

• Wearable Microphones

Wearable microphones, such as lapel and headset mics, enable speakers to operate entirely hands-free, making them perfect for lectures, training sessions, and video calls. These microphones ensure reliable voice recording, even when the speaker shifts positions. Equipped with a headset jack, the microphone enables two-way conversations in virtual meetings.

• Tabletop Microphones

Tabletop microphones offer consistency and dependability for conference rooms with fixed seating layouts. These microphones can be attached to a table or used wirelessly for versatility. They function optimally when speakers stay still and at a short distance and guarantee clear and high-quality audio.

• Ceiling Microphones

Ceiling microphones offer a tidy audio solution that ensures superior room coverage compared to tabletop microphones. They are particularly advantageous for spacious conference rooms, as a single ceiling microphone can pick up sound from all directions. However, based on the room's dimensions and acoustics, several ceiling microphones might be necessary for the best clarity.

2. Common Microphone Pickup Patterns

A microphone’s pickup pattern determines how it captures sound from different directions. Choosing the right pickup pattern ensures better voice clarity and noise isolation.

• Directional Pickup Pattern

The cardioid pattern, or directional pickup pattern, mainly picks up sound from the front and minimizes noise from the sides and rear. Gooseneck microphones use a unidirectional pickup pattern. This makes it perfect for presentations, lectures, and discussions, where attention is on one speaker. Although it aids in reducing background noise, speakers need to remain within the microphone’s reception range for the best clarity.

• Bidirectional Pickup Pattern

A bidirectional pickup pattern records sound from two opposing directions. However, it reduces sound pickup from the upper and lower angles, rendering it less efficient in spacious meeting areas. This pattern is most effective in close conversations or meetings where two individuals are positioned facing one another.

• Omnidirectional Pickup Pattern

The omnidirectional pickup pattern picks up sound uniformly from every direction, making it ideal for group conversations, roundtable discussions, and conference calls. As it captures 360-degree sound, it enables several speakers to converse at the same time without requiring separate microphones.

3. Factors When Choosing the Best Conference Microphone

Selecting the right conference room microphone involves multiple considerations. Below are six key factors to help you make the best choice:

• Room Size and Setup

The size and setup of your conference room are vital factors in choosing the right microphone. Room Size of 1-6 people: Tabletop or speakerphone microphones can be used. Larger spaces of 6-12 or more than 12 people need ceiling or several wireless microphones. A strategically positioned microphone guarantees clear dialogue and minimizes echo or areas of silence. 

• Audio Quality

An effective conference microphone must provide clear, natural audio and incorporate noise cancellation to eliminate background sounds. Elements such as echo elimination, AI voice optimization, and broad frequency response enhance the overall audio experience. Premium microphones employ beamforming technology to follow the speaker’s voice.

• Connectivity

Conference microphones come in different connectivity options:

Wired Microphones: Provide stable connections but may limit flexibility.

Wireless Microphones: Offer freedom of movement but can be affected by interference.

USB microphones: Easy to plug in and use and ideal for small meeting rooms.

Bluetooth microphones: They are Convenient but may have latency issues.

• Compatibility with Existing Systems

Selecting a microphone that works seamlessly with your video conferencing software, like Zoom, Teams, Google Meet, and current audio-visual gear, is crucial. Certain microphones offer plug-and-play capabilities, whereas others need extra software or drivers.

• Additional Features

Seek out microphones integrated with mute buttons, voice tracking, AI-enhanced audio, and multiple microphone configurations to improve user experience. Certain advanced models provide automatic speaker identification, allowing attention to be directed toward the current speaker during conversations.

• Budget

The price of conference microphones varies based on features, audio quality, and connectivity options. Understanding different budget categories can help you choose the best microphone for your needs.

Entry-Level: Basic microphones are more affordable but may lack advanced features like noise cancellation or wireless connectivity

Mid-Range: These typically offer good audio quality, noise reduction, and wireless options, making them suitable for most corporate meeting rooms. 

High-End: Premium microphones often include superior noise reduction, better build quality, and multiple connectivity options. 

4. Top 2 Options for Conference Microphones

Depending on your meeting setup and budget, you can choose between standalone microphones or integrated solutions like conference projectors or webcams with built-in microphones.

Standalone Microphones or Speakerphones

Standalone microphones are perfect for configurations where sound quality is important. Many standalone microphones or speakerphones utilize an omnidirectional pickup pattern. They are available in both wired and wireless options, providing versatility depending on the size of the room.  In small conference rooms designed for 4-6 participants, a microphone or speakerphone with a 3-meter pickup range is adequate, as the distance between attendees typically does not exceed 3 meters.

• Clear audio with noise cancellation.

• Available in tabletop, ceiling, and handheld models.

• Wired or wireless options for different room sizes.

Conference Projector or Webcams with Microphones

Conference cameras or webcams with built-in microphones offer an all-in-one solution by integrating audio and video functions. However, they are less flexible in placement compared to standalone microphones or speakerphones. Typically mounted on a TV or positioned near a wall to keep all participants in view, these devices require careful consideration of both room size and microphone pickup range to ensure clear audio for all speakers, including those seated farthest from the microphone. While they work well for small meeting rooms with 1-6 participants, larger rooms with more than 10 people may require additional standalone microphones or advanced conferencing solutions like StarryHub for optimal audio coverage.
