auto ZoomControl - Automatic focus wherever speech comes from.
The introduction of ZoomControl revolutionized directional hearing and set a standard for binaural processing. Auto ZoomControl takes this proven concept to the next level, automatically tracking and focusing on speech regardless of the direction, without the need to face the speaker.
Once activated, auto ZoomControl automatically selects the direction of the dominant speech source. When focusing to one side, the speech signal is amplified by the instrument on that side; simultaneously the entire signal is streamed to the other ear. As a result, the desired signal is heard in both ears, dramatically improving the signal-to-noise ratio (SNR). This unique feature provides natural listening in both ears.
Field study results show that compared to omnidirectional mode, ZoomControl provides an SNR improvement of 2–4 dB for signals coming from either side and 4–6 dB for signals coming from the back.
