The value of two ears for sound source localization and speech understanding in complex listening environments: : two cochlear implants vs. two partially hearing ears and one cochlear implant

Two groups of cochlear implant (CI) listeners were tested for sound source localization and for speech recognition in complex listening environments. One group (n=11) wore bilateral CIs and, potentially, had access to interaural level difference (ILD) cues, but not interaural timing difference (ITD) cues.
