Until then, the Electronic Ear sound system relied on analog sound processing. Under the direction of Alfred Tomatis, happens the first digital filters testing, in the Tomatis® Center in Paris. The results were very conclusive and opened the door to further developments.
The decade of the 1990s marked an important turning point with the standardization of procedures that offered a homogeneous application of the Method around the world.
To emphasize the seriousness and the ambition of the Tomatis® Method, there is the creation of an important partnership with Professor Skarżyński, from the famous Institute for the Physiology and Pathology of the Ear in Warsaw, Poland. This partnership will lead to the implementation of the Method in many schools in Poland.
