OpenSound Navigator OFF
Without OpenSound Navigator, the speaker in focus (A) stands out, but is very hard to distinguish between the secondary speaker (B) and the background babble (C) because the strength of the EEG signals are very similar.
OpenSound Navigator ON
With OpenSound Navigator switched ON, the strength of the EEG signal shows:
A) Speaker in focus: the signal is increased by 10% making it easier to follow the person the user is listening to
B) Secondary speaker: the signal is increased by 95% making it much easier to distinguish that speaker from background babble
C) Background babble: is reduced by 50% allowing the two speech signals to stand out and making listening is easier
