Intervention type: DEVICE
Group type: ACTIVE_COMPARATOR
Intervention: fNIRS
Description: The auditory cortical imaging will be performed by fNIRS measures. This non-invasive functional imaging technique relies on the use of a sensor-bearing cap, measuring cortical activity through scalp, during auditory stimulation. As head movement does not alter measurement that much, fNIRS is well adapted to children.

Intervention: Speech intelligibility
Description: Speech intelligibility will be evaluated with French sentences comprehension in noise, from the Common Test or Adaptive Auditive Speech Test before 6 years, from the Common Test or Hearing in Noise Test for Children (Hint-C) from 7 to 11 years, and from the Hint-C or Marginal Benefit of Acoustic Amplification after 11 years, both with a Signal over Noise Ratio of +10 decibel at 65 decibel

Intervention: Speech assessments
Description: Speech assessments will be performed by dedicated speech therapists, with child age specific tests, and 2 global speech scores: the Category of Auditory Performances scale - second edition, and the Speech Intelligibility Rating scale.

Intervention: Quality of Life
Description: Quality of Life (QoL) evaluation will be based on the generic QoL scale, and the Speech Spatial and Qualities of hearing (SSQ) deafness specific scale. Each scale exists in age specific modalities.
