STENTOFON Communications Australia have developed a software-based Active Noise Cancelling feature for their stations.
A powerful DSP inside the station will measure the microphone signal and calculate the noise components in that signal. It will effectively remove these noise components, leaving a clean speech signal even if the original speech level is below the level of the surrounding noise.
A major advantage of Active Noise Cancelling is the fact that the user does not need to speak closely into the microphone, which in certain circumstances.
The Active Noise Cancelling feature can be switched off 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 STENTOFON Communications Australia solution is purely software based, the Active Noise Cancelling feature can be added to IP-stations already installed.
Due to AlphaNet’s networking capabilities, the Active Noise Cancelling feature can be installed and configured remotely for widely dispersed locations.
