Inclusion criteria

Inclusion criteria: Part 1: Children, age * 8 years old; Bilateral stimulation (implanted either simultaneously or sequentially) and bimodal stimulation; NVA phoneme scores at 65 dB SPL of * 85% with bilateral cochlear implants; NVA phoneme scores at 65 dB SPL of * 85% with cochlear implant and * 50% with hearing aid in case of bimodal stimulation; Peers with normal hearing as a reference.;Part 2: Children, age * 8 years old; NVA phoneme scores at 65 dB SPL of * 85% best or only cochlear implant. Groups: Bimodal group: children with a cochlear implant and hearing aid with NVA phoneme scores at 65 dB SPL of *50% with the contralateral hearing aid; Bilateral group I: children with bilateral cochlear implants implanted sequentially, with substantial residual hearing on the secondly implanted side before surgery (NVA phoneme scores at 65 dB SPL * 50%); Bilateral group II: congenitally deaf children with bilateral cochlear implants, implanted simultaneously at a young age (

Exclusion criteria

Design outcomes

Primary

Measure	Time frame
Part 1: The difference in speech recognition in noise and localization acuity before and after loudness balancing with at least one month of adaptation. Part 2: The difference in primary auditory outcomes (i.e. speech recognition in noise, advanced localization acuity, prosody and listening effort) between children with BiCIs implanted sequentially and bimodally fitted children, both with well aidable hearing loss on the contralateral ear (prior to sequential bilateral cochlear implantation) and how these outcomes relate to those in children with BiCIs implanted simultaneously at a young age and children with normal hearing. Part 3: The difference in speech recognition in noise in two conditions (i.e. S0°N180° and S180°N0°) and localization acuity between a directional microphone and an omnidirectional microphone setting.	—
