Video Conference Audio Problems?

Five Tips For Avoiding Annoying Audio In Your Meetings

Video Conference Audio Problems?

Are you plagued with audio issues in your video and audio conferences?  The most common problem with audio in meetings is feedback.  Almost everyone experiences it whether it’s on a simple Skype call from your computer or a Zoom video conference across two packed conference rooms from Richardson to Shanghai.   

The main cause of that nasty feedback that makes for painful meetings is sound that emanates from speakers and is picked up by the microphone, creating a feedback loop.  Depending on the gain (volume) applied to the sound, some frequencies can be overly amplified in that loop to sound shrill or generate echoes.  When that happens, everyone has to start repeating what they said, or worse, conversations may be misunderstood – something you definitely want to avoid. 

So what’s the solution to cure these video conferencing audio ills in your Richardson meeting rooms?  Read on for some tips to optimize your conference room sound.

Move Microphones Close to Sound Sources

If the microphone is farther from the person speaking, more acoustic gain needs to be dialed into the system so that the person is heard loudly enough on the other end.  Have you ever asked someone to speak closer to the microphone in a call?  If they don’t, you might turn up the volume, but then it picks up other unwanted sounds.  Ideally, you want microphones as close as possible to the locations where people will be speaking, 

Move Speakers Closer to Listeners

Distributed ceiling or wall-mounted speakers are a solution to providing even sound coverage in a conference room.  But there is an art and science to installing them properly, to ensure that the sound level is correct for those seated further away from a speaker. Professional calibration and installation can ensure that your room’s gain is correct, allowing everyone to hear the sound without introducing unwanted feedback.

Use Directional Microphones If Possible

Omnidirectional microphones are designed to capture sounds from all around.  But they can also gather unwanted noises with equal gain.  Directional microphones can help for some positions in a room, minimizing ambient noise, and applying maximum gain to the sound of the meeting participants close to it.  The right combination and tuning of microphones will optimize the sound clarity of meetings. 

Tune the Room With Signal Processing

There are a couple of ways to do this.  One is manually, where we can tune your audio system sound with an equalizer, in much the same way a home theater sound system can be optimized.  The other is with microphone arrays that employ signal processing, and have digital tuning that can be applied.  Either way, the objective is to tame the harsh frequencies that can cause problems with your room’s sound at maximum volumes. 

Acoustic Treatment

Some rooms have frequencies that are more resonant than others.  Hard surfaces in conference room tables, walls, and flooring can all contribute to too much reverberation. Acoustic treatment with sound-absorbing panels and material in walls and ceilings can help tame those frequencies, resulting in a room where video conferences at low or high sound volumes can all sound normal and not jarring.
