Don’t Forget the Audio in Video Conferencing—Four Tips for Success

Updated: Apr 6, 2018

Four important steps you can implement to ensure high quality audio is part of your video conferencing system.


Video conferencing has become a staple of successful business communication today. Whether it’s collaborating with employees or clients, video conferencing offers businesses new and effective ways to interact with various stakeholders despite geographical location.


An often overlooked, but crucial for the overall successful implementation of video conferencing technology is quality audio. Without clear and coherent audio, the multiple benefits of video conferencing are nullified. Here are four important steps you can implement to ensure clients achieve high quality audio as part of their video conferencing system.



1. Build a Space-Specific Audio System

When clients are purchasing a video conferencing system, they tend to focus more on video than audio.


Most clients desire a clear and high resolution video stream in their conference room.


While ensuring high quality video is important, designing and deploying the audio portion of a video conferencing system is equally, if not more, important to the overall functionality and success of the system.


In larger spaces and conference rooms, bigger speakers are often required to help evenly disperse the sound. Effective video conference sessions are all about inclusion and communication as well as building a space-specific audio system to ensure everyone is hearing the same message clearly.


Beyond speaker size, installing acoustic treatments in larger spaces will help reduce audio echo and reflection.


2. Eliminate Background Noise and Cross Talk

Background noise is frequently much more problematic for clients than audio drop out. Video conferencing is meant to enhance communication, but background noise can detract from that objective and actually contribute to instances of miscommunication.


Whether the background noise is coming from another room or from personal devices in the video conferencing space itself, audio clarity depends on the elimination of background noise.


Much of the background noise that occurs during video conferencing sessions originates from employee’s mobile devices or other rooms adjacent to the conference space.


In order to mitigate the adverse effect of this background noise, it’s important for audiovisual integrators to educate their clients on proper personal device protocol they should employ during video conferencing sessions.


3. Eliminate Cross Talk

The effectiveness of video conferencing also hinges on the elimination of cross talk. A certain amount of cross talk is inevitable through normal activities, but clients don’t realize that this can have unintended consequences.


For example, if clients are using antiquated technology such as a half-duplex audio system, then cross talk can nearly paralyze productivity during video conferences.


In order for clients to eliminate these negative effects, it’s vital they understand and consider the benefits of a full duplex audio system.


4. Choose the Right Microphone

Choosing the best microphones for your clients’ needs is ultimately the most important factor to ensure the best possible audio clarity during video conferencing sessions. For clients that have multiple people participating in a video conference, AV integrators need to consider using microphones with selectable coverage patterns.


A microphone with directivity will automatically highlight the speaker. This will ensure that each participant is heard with clarity. Another consideration when choosing a microphone is the size of the conference space. Larger spaces tend to generate more ambient noise that can picked up by normal omnidirectional microphones.


However, microphones with selectable coverage patterns automatically reject unwanted ambient sounds to allow the speaker’s voice to be heard loud and clear.


The Takeaway

Video conferencing has become an important collaboration tool for businesses in every industry. While many clients believe that video quality is more important than audio clarity in the overall success of a video conference, this is simply not true.


In order for video conferencing to be successful, it’s important to consider audio quality equally. In summary, to build a high quality audio system, it must fit the available space, eliminate background noise and cross talk and utilize the best microphones for your clients’ needs.


Following these steps will ensure high quality audio when designing and installing video conference systems.
