Working remotely continues rising, with forecasters predicting 25-30% of professional employees sustaining hybrid or fully-distant work setups through 2025.
Video meetings serve as the lifeline enabling this ongoing workplace shift. Global video conferencing traffic expanded an eye-popping 1000% between December 2019 and December 2021 as per TeleGeography.
And Vidyo reports stark differences in meeting effectiveness with subpar audio: video conferences rated extremely productive fall from 65% to 35% when audio problems arise.
Investing in audio visual upgrades pays tangible dividends through more engaging meetings, narrowed communication gaps across distributed attendees and lowered collaborative friction.
This guide explores the key considerations around conference room microphones empowering your company’s conferencing audio excellence. Let’s examine:
- Advancing microphone hardware capabilities
- Product feature sets answering diverse usage needs
- Configuration best practices optimizing deployments
- The roadmap of innovations still to come
Advanced components inside sophisticated conference room microphones account for immense leaps in VoIP call quality. Let‘s geek out on what‘s now possible.
Microphone Technologies Critical for Video Meeting Audio Clarity
While superficially seeming simple devices, advanced internals give modern conference room microphones incredible capabilities fine-tuning call audio.
Microelectromechanical systems (MEMS) based mic components distill physical sound waves into optimized electrical signals. Enhanced digital signal processor (DSP) algorithms further translate signals eliminating artifacts and interferences.
Sensitivity and Frequency Range
A key MEMS specification is sensitivity measuring required acoustic input loudness for quality detection across the operational frequency spectrum. Higher sensitivity mics require less volume for their electronics to discern rich input detail.
Top speakerphones now reach -40 dB sensitivity ratings able to discern fine nuances even from distant whispered speech.
Frequency range depicts the spectrum of high and low tones translated by the mic. Wider 20 Hz to 20 kHz frequency coverage captures deeper harmonic texture.
Directional Pickup Patterns
Microphones use clever physical and digital configurations targeting audio sources while minimizing ambient cacophony.
Omnidirectional mics utilize sensitivity uniformly across 360-degrees exposure. Cardioid mics use physical sound baffling on the rear and backsides to accept mostly forward-aimed input. Bidirectional mics also use physical components to intake from front and rear sources.
Beamforming relies on DSP algorithms to electronically synthesize directionality. By calculating tiny time of arrival and level discrepancies across an array of omni mics, beamforming dynamically focuses on voices while suppressing ambient noise.
Sophisticated implementations combine physical layouts with multiple DSP channel beamforming for exquisitely honed directionality and noise rejection.

Acoustic Echo Cancellation and Noise Reduction
Audio coming from room loudspeakers often enters mics causing confusing echo. Acoustic echo cancellation (AEC) applies DSP to identify and subtract this artifact in real-time.
Additive background noise also washes out clarity. Noise reduction routines factor out consistent sources like HVAC systems and typing. Next generation approaches even eliminate transient noises like paper rustling by analyzing the signals.
By assembling these capabilities together into multi-mic arrays with heady processing, conference rooms can now achieve pristine broadcast quality conversation pickup across a variety of tricky environments.
