“…Bimodal CI users experience a considerable benefit when using spatial noise reduction algorithms (‘beamformers’) as has been shown in multiple studies that tested their speech-in-noise performance in simplified and realistic acoustic scenarios ( Buechner, Dyballa, Hehrmann, Fredelake, Lenarz, 2014 , Devocht, Janssen, Chalupper, Stokroos, George, 2016 , Ernst, Anton, Brendel, Battmer, 2019 , Vroegop, Homans, Goedegebure, Dingemanse, Immerzeel, van der Schroeff, 2018 , Weissgerber, Rader, Baumann, 2017 , Zedan, Jürgens, Williges, Kollmeier, Wiebe, Galindo, Wesarg, 2021 ). The simplest group of beamformers are monaural beamformers (i.e., implemented in a single hearing device) which use the signals of two or more microphones to reduce the noise on one side of the listener, e.g., only the HA side or only CI side ( Ernst et al., 2019 ).…”
