PRINCE22 System Complete Performance Study

Feature Supporting Multitasking of Visual and Acoustical Objects

The investigation proposes to compare a narrow reference beamformer to a novel beamformer approach, when the talker is not in front of the hearing aid user and in the presence of background noise. The beamformer effect will be determined in terms of speech intelligibility, listening effort and ability to multitask when the talkers are located on the side or in the back.
