The Polycom VVX 201 phone is a step up from the VVX 101, by offering Polycom HD Voice technology. Voices sound as true-to-life as though callers were standing in the same room. The benefit is reduced listener strain and more fluid conversations.

An overview of Acoustic Fence

Acoustic Fence is a relatively new technology, exclusive to Polycom Group series video conferencing systems and VVX series phones. What the technology does for VVX phones is dramatically improve call quality by blocking background noise and, when necessary, muting the microphone.

The technology recognizes the user’s voice and only allows his or her voice to enter the phone’s microphone. In cases such as when callers are in a conference, the technology can mute participants with noisy microphones—noises caused by crumpling papers, etc. When that participant starts speaking, the microphone will unmute.

Noise cancellation technology typically works by emitting inverse sound waves into the environment, and cancelling out the offending noises. Polycom Acoustic Fence technology takes advantage of all of the phone’s hardware to ensure that conversations are distraction-free.
