A methodical evaluation of new CE-labelled Phonak Hearing Systems is intended to be conducted on hard of participants with a hearing loss to grant quality control prior to product launch. The aim of the investigation series is to ensure a stable overall performance of the new hearing systems, a good sound quality during phone calls as well as maximum benefit for the participant with the devices.
The purpose of this feasibility study is to evaluate whether implantation of one Nucleus L24 electrode array and one FDA approved standard-length device in the contralateral ear can provide useful binaural hearing in pediatric subjects who have bilateral severe to profound hearing loss, meeting the criteria for cochlear implantation. Unlike a conventional cochlear implant, the Nucleus L24 is expected to preserve the regions of the cochlear partition that are apical to the electrode, thus leaving them available for possible future advances in the field of otolaryngology and hearing devices, such as mammalian hair cell regeneration techniques or improved implantable hearing devices. Whether or not this group of children will be able to take advantage of future hair cell regeneration strategies is yet to be determined and will have to wait for future development. At this time there are no accurate imaging strategies available to identify preservation of the scala media. Ultra thin micro CT scanning is in development, however the level of radiation delivery to the subject is too great to be considered for clinical use. When imaging strategies become available to determine cellular structure of the inner ear, they will be applied to this group of subjects. The Nucleus L24 array stimulates the basal turn of the cochlea, in an attempt to preserve the middle and apical regions of the scala media.
A methodical evaluation of new CE-labelled Phonak Hearing Systems is intended to be conducted on hard of participants with a hearing loss to grant quality control prior to product launch. The aim of the investigation series is to ensure usability, zero-defect overall performance of the new hearing systems as well as maximum benefit for the participant with the devices in comparison to previously outstanding Phonak Hearing Systems.

To evaluate performance outcomes in patients implanted with the Cochlear Nucleus CI532 electrode array.
The reason for this study is to evaluate a new hearing aid product generation replacing the one on the market. The goal is to evaluate the audiological performance, usability as well as features and functions.
The purpose of this study is to evaluate whether the Iowa/Nucleus 10/10 mm in one ear, in conjunction with a Nucleus Freedom implant in the other ear can provide useful binaural hearing in pediatric subjects who have bilateral severe to profound hearing loss and meet the criteria for cochlear implantation. The Iowa/Nucleus 10/10 mm cochlear implant has a short, 10 mm electrode array that it is inserted only into the more basal region of the cochlea. Unlike a conventional cochlear implant, the Iowa/Nucleus 10/10 mm is expected to preserve the regions of the cochlear partition that are apical to the electrode, thus leaving them available for possible future advances in the field of otolaryngology and hearing devices, such as mammalian hair cell regeneration techniques or improved implantable hearing devices. The Iowa/Nucleus 10/10 mm will be implanted in the contralateral ear from the Nucleus Freedom electrode array as a means of providing bilateral stimulation of auditory pathways while preserving the middle and apical regions of the scala media.
