Corporate AV System Commissioning & Verification
Corporate AV systems span boardrooms, training rooms, all-hands spaces, and huddle rooms — each with different acoustic requirements and audio equipment configurations. SonaVyx provides the measurement tools for AV integrators and IT teams to commission installations, verify specifications, and troubleshoot audio quality issues across entire corporate campuses.
Key Challenges
- Ceiling speakers and microphones requiring even coverage across large conference tables
- Video conferencing systems producing echo and poor speech clarity in reverberant rooms
- Inconsistent audio quality between meeting rooms with identical equipment but different acoustics
- AV control systems applying default DSP settings without room-specific calibration
- Large-format all-hands spaces with reinforcement systems requiring delay alignment
Recommended Tools
Transfer Function
Verify ceiling speaker frequency response and coverage uniformity across seating positions
STI Measurement
Confirm speech intelligibility exceeds STI 0.60 for video conferencing quality communication
SPL Meter
Measure background noise NC rating and set reference levels for AV playback systems
RT60 Calculator
Assess room reverberation to predict video conferencing echo cancellation performance
Measurement Workflow
- 1
Assess Room Acoustics
Measure RT60 and background noise in each room type. Conference rooms: RT60 < 0.6s, NC < 30. Training rooms: RT60 < 0.7s, NC < 35. All-hands: RT60 < 0.8s, NC < 35.

Verify Speaker Coverage
Play pink noise through ceiling speakers. Measure SPL at each seat position and at corners. Variation should be within 3 dB across the conference table area.
- 3
Check STI
Run STIPA measurement at the seat farthest from the nearest ceiling speaker. STI should exceed 0.60 for comfortable intelligibility during video calls and presentations.
- 4
Test Microphone Pickup
Speak at normal conversational level at each seat. Verify consistent audio level in the far-end video conference system. Note dead zones in microphone coverage.
- 5
Calibrate Reinforcement
For rooms with local reinforcement, adjust DSP gains and EQ using transfer function measurement. Ensure reinforcement does not exceed the direct speech level to maintain natural sound.
- 6
Document and Standardize
Create a commissioning template with pass/fail criteria for each room type. Document DSP settings, coverage maps, and acoustic measurements for each installed system.
Corporate AV audio quality directly affects meeting productivity, remote employee engagement, and the perceived professionalism of the organization. When conference room audio works well, participants forget about it entirely. When it does not — echo, distortion, uneven coverage, or unintelligible remote participants — meetings become frustrating and communication suffers. SonaVyx provides the objective measurement framework to commission AV systems correctly and maintain consistent quality across corporate facilities.
Room Types and Acoustic Targets
Corporate environments include diverse room types with different acoustic requirements. Huddle rooms (2-4 people) need very short RT60 (0.3-0.4 seconds) and low background noise (NC-25) because ceiling microphones must pick up quiet conversational speech. Standard conference rooms (6-12 people) tolerate slightly longer RT60 (0.4-0.6 seconds) but require even ceiling speaker coverage across the entire table. Training rooms and all-hands spaces (20-200+ people) need reinforcement systems with proper delay alignment and STI verification.
SonaVyx measurement establishes the acoustic baseline for each room and identifies whether audio quality issues stem from room acoustics, equipment configuration, or both. Many corporate AV problems attributed to equipment are actually caused by room acoustics that the DSP cannot fully compensate for.
Video Conferencing Audio Quality
Echo cancellation algorithms in platforms like Teams, Zoom, and Google Meet perform significantly better in acoustically treated rooms. When RT60 exceeds 0.5 seconds, AEC must work harder to separate direct speech from reflections, often producing audible artifacts — clipped words, double-talk suppression, and residual echo. SonaVyx RT60 measurement predicts AEC performance and identifies rooms that need acoustic treatment before video conferencing systems can perform at their best.
Ceiling microphone arrays are particularly sensitive to room acoustics because they are positioned far from speakers, maximizing the ratio of reverberant to direct sound. SonaVyx STI measurement at each seat position quantifies how much speech energy the microphone receives versus room noise and reverberation, directly correlating with far-end audio quality.
Campus-Wide Standardization
Large corporate campuses may have hundreds of meeting rooms requiring consistent audio quality. SonaVyx venue management system lets AV teams create commissioning templates with standard measurement positions and pass/fail criteria for each room category. Measurement results are stored per venue, enabling trend tracking over time and rapid identification of rooms that have degraded since installation.
Standardized commissioning procedures also help when troubleshooting complaints. Rather than relying on subjective reports, AV support teams can re-measure a problem room and compare current results against the commissioning baseline, quickly identifying whether the issue is acoustic (room changed), equipment (speaker or microphone failure), or configuration (DSP settings modified).
