We begin to hear before being born. A child's hearing develops through the variety of sounds in which he/she has been steeped since the fourth month of the gestation period. The child's ear progressively learns to select certain sounds among all those that come to him/her into his/her mother's womb. We may lose our ability to hear.

If for one reason or another, we do not feel welcome to the world - birthing complications, separation from the mother, tensions in the family, for example - we may react by unconsciously closing our ears as a way to protect ourselves.

As a consequence, our ear "tunes out" to certain sounds, often to those that are necessary to learn language and to develop learning abilities. This hearing loss may also be due to ear infections among other reasons. It may lead the child to reading troubles or dyslexia, which may handicap his/her social life or self-confidence.
We can restore our ability to hear.

By recreating the sound universe in which the child has grown up, his/her intra-uterine life, his/her coming into the world, and then the way he/she has learned language, this approach can help rid the child of what originally blocked his/her desire to hear. It enables the child to progressively acquire a better ear and to find the way to hearing again in the best possible conditions.

Every child takes a specific step.
Five main phases are often common but are carefully adapted to everyone's own needs.

1. Musical sonic rise
2. High harmonics (passive phases)
3. Higher frequencies
4. Language welcoming: pre-language.
5. Language exercise

During the sessions, educationalists specialised in hearing follow the progress of every child. They encourage communication through artistic and play activities, conversations, stories or songs for younger children.
The headphones that the child has to wear are equipped with a long cord, which enables him/her to move and play. The atmosphere in the centre is cheerful and there is no pressure. So the child can progressively enter a phase which is more active linguistically speaking. For his/her desire to communicate intensifies, we then give him/her the technical tool to develop new communicative and learning abilities.
At this stage, some speech therapy may sometimes be useful.
