Are Your Video Conference Room Acoustics HD-Compatible?

There are many market factors driving the growth of video conferencing, and manufacturers like Polycom and ClearOne have responded with better technology. These modern video conference systems offer bigger displays, higher resolution video, high definition audio quality, integration with mobile apps, and so on. However, if this advanced technology is installed in a poorly designed conference room, the results can be disappointing. A good conference room design and system installation takes into many factors, including lighting, background color and patterns, camera and video display locations, microphone and loudspeaker type and placement, background noise, and room acoustics. This post will focus on ways that the room design can enhance or reduce the audio quality of the system. A follow-up post will provide more detail on good room design principles to get the best audio quality possible out of any videoconferencing system. The advent of HD audio quality Traditional video and teleconferencing systems relied on telephone connections for communication, which inherently limited the audio quality. For example, landline phones are filtered to a narrow range of frequencies that are most important to speech intelligibility. As a result, voices can still be understood, but they don’t sound as natural as they would if you were in the same room with the person. Compare these two audio files to see if you can hear the difference in quality: unfiltered audio  audio with telephone filter As we move away from landlines to cell phones and VOIP systems, there are other ways that audio quality can be compromised. High quality digital audio requires a lot of data and causes network congestion. Phone systems try to...
