A cochlear implant (CI) is the only device which restores binaural hearing. The effect of microphone directionality (MD) settings has been investigated in other CI indication groups, but its impact on speech perception in noise has not been established in CI users with SSD. The focus of this investigation was, therefore, to assess binaural hearing effects using different MD settings in CI users with SSD.\n<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Twenty-nine experienced CI users with SSD were recruited to determine speech reception thresholds with varying target and noise sources to define binaural effects (head shadow, squelch, summation, and spatial release from masking), sound localization, and sound quality using the SSQ12 and HISQUI<jats:sub>19<\/jats:sub> questionnaires.

In both groups, a significant head shadow effect of 7.4\u20139.2\u00a0dB was achieved with the CI. The MD setting \u201cadaptive\u201d provided a significant head shadow effect of 9.2\u00a0dB, a squelch effect of 0.9\u00a0dB, and spatial release from masking of 7.6\u00a0dB in the SONNET group. No significant summation effect could be determined in either group with CI. Outcomes with the omnidirectional setting were not significantly different between groups. For both groups, localization improved significantly when the CI was activated and was best when the omnidirectional setting was used. The groups\u2019 sound quality scores did not significantly differ.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Adaptive directional microphone settings improve speech perception and binaural hearing abilities in CI users with SSD.
