Its function - Listen to the Tomatis Effect
The chosen musical works are rich in harmonics (frequency-relative richness), which is necessary to make the electronic gating work. The works used are generally Mozart’s concertos for the violin, specially-treated with the TOMATIS effect.
Electronic gating creates the « TOMATIS effect »
The TOMATIS devices are designed to establish a unique sound perception contrast. This effect causes the contraction and relaxation of the inner ear muscles. This to-and-fro movement is made possible by the sudden transition from lower, bass frequencies, which do not require any particular effort on the part of the ear, to higher, acute frequencies, which require the ear to make a special effort to accommodate. This activity is much like a gymnastic exercise for the ear, which, thanks to repeated activity and to the progressive mobilization of the ear, optimizes the transmission of the sensory sound message to the brain.
The programming of the devices (the choice of musical works, the filtering, the auditory laterality, the speed of the gating….) and the design of the listening sessions are determined by the trained professional depending on the subject’s problems or difficulties.
