Clinical Trial Summary

The hypothesis of this research is that the AS Target setting provides the best estimate of the settings required to optimize listening in noise. As such, it is expected that speech in noise performance will be best in the AS Target condition, followed by the AS Clinic condition, and the Omni condition will be the least favourable for speech in noise performance

Description:

The ability to hear speech in noise is particularly important for children, as they are often in complex listening situations like classrooms or playgrounds. In children with hearing loss, the ability to understand speech in noise is further degraded not only by decreased audibility of speech sounds, but also additionally by the distortion spectral and temporal processing cues, and reduced binaural processing abilities. Cochlear implant manufacturers have introduced a number of technologies designed to improve speech recognition in background noise. Sound processing algorithms use a variety of strategies to facilitate listening in noise, and research has shown that these advances do lead to improved performance.

AutoSense Sky OS 3.0 (AutoSense Sky OS, AS) is an automatic auditory scene classification system specifically designed for children's typical listening situations, like classrooms and playgrounds. This technology is available in the new Sky CI M90 (Sky CI), which is the latest generation of sound processor (SP) from Advanced Bionics, designed for children.

This algorithm is also available in the Sky Link M90 hearing aid (Sky Link). This means that bimodal patients, using one Sky Link and one Sky CI can benefit from AutoSense Sky OS in addition to children with two Sky CI. The combination of the two hearing devices (HD) tested in this research, whether it be two Sky CI or one Sky CI and one Sky Link, will be referred to as the Sky Hearing System (Sky HS).

As usual in standard care, children with Sky HS can have their hearing system programmed in three ways (at the discretion of the clinician):

1. Omnidirectional mode, in which the AutoSense Sky OS is deactivated and no modifications are made by the clinician (no sound treatment)

2. AS Target, in which the AutoSense Sky OS is active and programmed with the parameters suggested by the programming software (Target) and no modifications are made by the clinician

3. AS clinic, in which the AutoSense Sky OS is active, and settings have been modified by the clinician (mixed setting).

The goal of this research is to compare speech in noise perception in each of those three possible programming conditions used in the standard care. The hypothesis of this research is that the AS Target setting provides the best estimate of the settings required to optimize listening in noise. As such, it is expected that speech in noise performance will be best in the AS Target condition

Intervention

Device:
• Cochlear implant processor Sky CITM M90 (CI-5295)
The Sky CI available to included patients (no procedures added) offers the AutoSense Sky OS technology with the three following programming conditions possible. This three condition are fitting and evaluated in noise 6 months after inclusion: Omnidirectional mode : no sound treatment AS Target : Autosense is active and no modifications are made by clinician AS Clinique : Autosense is active and modified by the clinician
• Hearing Aid, including sound processor Phonak: Sky Link M90
The device is fitting and programmed for home especially for the purpose research at inclusion. The Clinical map parameters will be verified according to clinical routine. The Sky Link offers the AutoSense Sky OS technology with the three following programming conditions possible. This three condition are fitting and evaluated in noise 6 months after inclusion: Omnidirectional mode : no sound treatment AS Target : Autosense is active and no modifications are made by clinician AS Clinique : Autosense is active and modified by the clinician

Diagnostic Test:
• French simplified matrix test (FraSimat)
The FraSimat speech in noise test will be tested, 6 months before inclusion in the three different fitting configurations: omni, AS clinic, AS Target. The speech will be presented from the front, noise from 180°. Noise will be presented at a fixed level of 65 dB SPL while the speech signal will be adapted to find the 50% speech reception threshold (SRT).

Behavioral:
• Audiologist Fitting Questionnaire
After the fitting of Hearing Aid at inclusion, the audiologist will complete a questionnaire describing the fitting and justifying fitting decisions and will collect the demographic information
• Patient Satisfaction Questionnaire
The patient will be giving a Patient satisfaction Questionnaire, with questions regarding device and accessory use. The audiologist will go over the instructions for filling out the questionnaire at inclusion. Patients will be asked to complete the questionnaire and return it at the next visit, 6 months after inclusion.
• AutoSens Feedback Discussion Form
6 months after inclusion and fitting, the audiologist discusses the use of AS clinic with the subject and completes the AS questionnaire (questionnaire on the experience of using the processor in different listening situations).
