Key Term Definitions
Acoustic Clarity Technology:
This Polycom patented technology allows you to enjoy instantaneous natural conversation. When paired with a full duplex speakerphone, echo is eliminated and both callers are able to speak simultaneously without experiencing voice dropouts. The voice clarity on conference systems that feature this technology is incredibly crisp and clear.
Dynamic Noise Reduction:
One of Polycom's signature features, Dynamic Noise Reduction (DNR) eliminates the unwanted background noise that plagues more traditional conferencing methods. This technology was first introduced in the 1980's and targeted noise reduction in long distance communications. DNR can cut down clatter by as much as 10 decibels and can be paired with similar systems. The Polycom systems that carry this feature provide the user with optimum microphone sensitivity while removing dynamic noise. DNR can really make a difference when conferencing with client's long distance, the level of professionalism will be much appreciated.
Remarkable Voice Quality:
This feature is a result of the acoustic clarity technology and full duplex speakerphone functions. Members from both sides of the conference call hear one another clearly and talk at the time without experiencing static or echo.
All microphones have directional characteristics, which are determined by the way a microphone picks up sounds. Microphones can pick up signals from several directions or from one focused point. A cardioid microphone, the most popular of conferencing systems, picks up sound/signals primarily from the front of the microphone. When the pattern of cardioid sound pickup is graphed the shape resembles that of a heart, hence the name. These microphones focus on the sound in front of them and lessen ambient noise from the back or sides.
Analog is the original telephone technology, a system that converts air vibrations (like those created by the human voice) into similar electrical frequencies. Analog lines can support phones, fax machines, and modems and are typically found in homes or small office settings. Analog systems measure data in one continuous variable while digital breaks down and manipulates the data. One of the advantages of analog systems is that they dot not require a filter for band-limiting. Several SoundStation models operate on an analog system with features that are specifically designed for day to day communication.
Intelligent Microphone Mixing:
This feature can be found in the Polycom extension microphones line, a great tool when conferencing with multiple people in the room. The intelligent microphone mixing technology makes it so the only microphone turned on for clear conferencing is the one closest to person speaking. Why have microphones that are not in use turned on, this only creates unwanted, static noise that interferes with communication. This intelligent Polycom feature eliminates the guessing game that comes with finding the correct microphone, simply start speaking and the system will recognize which device to turn on.
