- Difference in speech intelligibility between the reference beamformer and the novel beamformer approach (percentage of correct responses in word recognition) in a noisy situation with speech from the side and from behind.
研究概览
简要总结
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.

结局指标
主要结局
Difference in speech intelligibility between the reference beamformer and the novel beamformer approach (percentage of correct responses in word recognition) in a noisy situation with speech from the side and from behind.
时间窗: 4 weeks
Two directional conditions (better ear side, back) and two beamformer conditions (Novel approach: SpeechSensor, Reference: StereoZoom) are tested (test and retest, eight measurements in total).
次要结局
- Difference in speech recognition threshold between the reference beamformer and the novel (mean value of 10 repetitions).(4 weeks)
- Difference in subjective speech intelligibility between the reference beamformer and the novel (subjects rate his/her perception of the presented speech).(4 weeks)
- Difference in multitasking ability between the reference beamformer and the novel (1. Respond on two trigger words / 2. Respond on a target sign).(4 weeks)
