Specificities of the method

Tomatis 
On average, 2h/day of listening to transformed music - for 1 to 2 weeks / to be repeated on average 3 times
Program adapted to individual needs, determined by a 60-90min listening test

Prerequisite: Listening test to identify current listening skills and areas for improvement.
Daily listening for 2 hours of sound supports (Mozart's music, Gregorian chants, waltz, mother's voice, nursery rhymes, etc.) which are transformed by the "Electronic Ear" (a listening gymnastics device), which will filter the sounds and thus stimulate listening through air conduction (headphones) and bone conduction of sound (conduction of sounds through the bones of the skull).

The electronic ear
It is a listening gymnastics device, which will filter sounds and thus stimulate listening through air conduction (conduction of sound through the air by means of headphones) and bone conduction of sound (conduction of sound through the bones of the skull). 
How it works: when the sound has an amplitude below a certain level, the low frequencies are amplified while the medium and high frequencies are filtered out. This happens on channel 1 of the Electronic Ear. However, when the amplitude increases just above a tipping point, the low frequencies are suppressed while the rest of the frequency spectrum is amplified. This occurs on channel 2. The Electronic Ear also contains mechanisms that can establish a delay between bone and air conduction of sound. The passage from one channel to another can be delayed on air conduction. 
Result: the muscles of the middle ear are trained to regulate tympanic tension and promote optimal listening to sounds and a better perception of the different frequencies by the brain.

iLS  
ISL programs generally last 30 to 60 minutes and are performed 2 to 5 times a week. Each session consists of four 15-minute music tracks combined with movement activities (preferably done at the beginning), followed by listening alone in a quiet environment. (a session can be done in 2 times).

There are different programs depending on the objective / difficulties of the child : 
Sensory and motor program (60 sessions)
Concentration and Attention Program (40 sessions)
Reading and Hearing Treatment Program (40 sessions)
Optimal Performance Programs I and II (two versions, 24 sessions each)
Emotional regulation & relaxation program (with or without singing) 10 sessions
Each program contains the full spectrum of sound frequencies of human hearing (20-20,000 Hz.), but the duration of each frequency band varies from program to program, in order to emphasize some more than others.

For example, a child with reading or language difficulties may listen to specific pieces of music that emphasize what is called the "language frequency range", 750-4,000 Hz, to improve the perception and discrimination of language sounds needed for decoding and phonemic awareness. These skills are essential for reading fluency.

The program can easily be done at home (with or without supervision by a therapist), but requires a certain amount of rigor.

ILs is possible in babies, the duration is of course adapted to the child's age. 

Movement exercises include a combination of balance, visual reinforcement and self-regulatory activities.
The program includes a combination of activities to improve eye-hand coordination, crossing the midline, balance and visual tracking.
There is a programme called "initial development" for those who need to develop simple motor skills. The aim of these activities is to strengthen muscles, the centre of the body, posture, control and stability, motor coordination, and basic eye tracking. Depending on the stage of development, they can be performed lying down, sitting on the balance board or standing on the balance board with support and simple visual tracking tasks. 
Gradually, the movements become more complex and include a combination of multisensory activities, and cognitive activities (e.g., numeracy) are also integrated to create a more complex environment.

Neurologic music therapy: 

The therapist may use so-called "receptive" music, i.e. listening to recorded music, followed or not by discussion/verbalization, possibly associated with another medium (drawing, dance, etc.) or other techniques (visualization, for example).

Most often there is some verbalization, depending on the patient, his pathology, his age, etc. 

Sessions can be individual or group and rarely last less than 15 minutes (with toddlers for example), rarely more than 2 hours (with large groups). Individual sessions last on average 30 to 60 minutes.
