Ten adults who had never worn hearing instruments were fitted binaurally. Audiometric thresholds ranged from 0 to 50 dB HL at 250 and 500 Hz, and from 40 to 75 dB HL at 2 and 4 kHz. The instruments were adjusted to NAL-r in omnidirectional mode via REIG measures. The directional mode of the ITEs was found to produce a substantial reduction in gain at rear azimuths relative to omnidirectional.
Results suggest benefit of the directional mode for at least some subjects.
