Babble noise is a typical and specific problem in open offices and call centers, which is why workers in these environments use headsets. Babble noise causes disturbance in these spaces, and it easily leaks through typical send noise suppression processing to far end in telecommunication. To improve the send direction signal-to-noise ratio, headsets are equipped with microphone booms with acoustic noise cancelling microphones or microphone arrays. A method to evaluate their efficiency in reducing babble noise is described in this paper.
