The Scientific Research behind Soundsory

SOUNDSORY® inherited from years of knowledge, research and technology thanks to the TOMATIS® Method, a neurosensory stimulation technique used in over 3800 therapeutic institutes and language centres in over 75 countries. The designers of Soundsory are the owners of the Tomatis method. The design of Soundsory originated from the conclusions of numerous scientific studies, some of which you can find here:
