Active Noise Cancellation comes as standard for all our IP stations
Having a conversation in a noisy area is difficult enough when you are talking face to face with your partner, and can be virtually impossible when using a communications system. Our Active Noise Cancellation is a software feature for Vingtor-Stentofon IP Intercom stations. A powerful DSP inside the station will measure the microphone signal and calculate the noise components in that signal. It will effectively remove unwanted noise components, leaving a clean speech signal even if the original speech level is below the level of the surrounding noise. The result will be a clear Open Duplex conversation even with a passing train in the background or talking from inside a car while stuck in front of a barrier.
A major advantage of Active Noise Cancellation above the use of a noise cancelling microphone is the fact that the user does not need to speak closely into the microphone, which in certain circumstances can be highly impractical or the need to do so may not be apparent at all to an occasional user.
The Active Noise Cancellation feature can be switched off, level setting 0, or be set to different levels. Level 7 will give a maximum noise reduction of over 36 dB. This way the station can be optimally tuned to the environment it is in.
Because the Vingtor-Stentofon solution is purely software based, the Active Noise Cancellation feature can be added to already installed IP-stations without any hardware modification whatsoever.
As the stations are connected to a data network, the Active Noise Cancellation feature can be installed and configured remotely for widely dispersed locations.
