In addition to the positive results achieved with our clients and which have made our reputation, our method has also proven its effectiveness scientifically. The research continues to grow as the areas of application of the method are extended. Indeed, the acoustic sensory message plays a key role in the development of the individual and, as a result, connects to a broad range of disorders.
The scientific partners with whom we work include several public bodies (ministries, research institutes, hospitals) as well as universities, specialised associations and foundations. Their involvement ensures the objectivity and reliability of the results presented for you in a non-exhaustive overview in the following tables.
Auditory Processing Study
|Auditory processing study||
TAPS subtests (test of auditory Perceptual Skills)
|Ross-Swain (The Swain Center) reviewed the pre / post treatment testing results of 41 selected clients that had Auditory Processing Problems which can affect listening comprehension.
After sessions of the Tomatis listening program, the results show a strong increase in ability to use memory to better listen and communicate.
|Auditory Processing Overall||8.4/58.3|
|Auditory Memory, digits||9.7/46.0|
|Auditory Memory, digits reversed||19.1/37.4|
|Auditory Memory, words||12.2/48.5|
|Auditory Memory, sentences||16.4/53.4|
|Following Directions||31.3 / 66.5|
|Du Plessis Study||Pre/ Post Anxiety Scores|
|Du Plessis (University of Potchefstroom, South Africa) studied 10 anxious university students who received the Tomatis listening program, 9 who received psychotherapy program and 10 assigned to the control group.
The Tomatis group showed significant reductions in anxiety, while the results were mixed for the psychotherapy group and no change in anxiety was found in the control group.
Another Du Plessis' study showed that the Tomatis group had maintained its reduced level of anxiety after 14.3 months and that the level of self-actualisation had increased significantly. No change was detected in the control group.
|CAS (Children's Anxiety Scale)||9.6/7.6||11.0/11.3||8.4/7.7|
|STAIC State (State-Trait Anxiety Inventory for Children)||32.8/27.6||30.7/28.1||31.3/30.0|
|Spaggiari report||N||Success %|
|Dr Spaggiara, psychiatrist, evaluated the impact of the Tomatis listening program on 409 people with psychological disorders.
The highest success rate was scored in treating Anxiety Disorders, where the success rate approached the level of success in treating learning difficulties (78%).
|Anxieties with Panic||45||72|
|Bipolar/ Manic/ Depressions/ Cyclotomia||97||58|
|D'Orthy Study||Pre/ Post (control group)||Pre/ Post (Tomatis group)|
|D'Orthy (Hospital Foch, near Paris), compared anxiety in a control group of 683 expectant women who received only the traditional preparation technique and 53 expectant women who received a shortened version of The Tomatis listening program.
The results showed a decrease in anxiety among the Tomatis mothers, whereas in the control group anxiety increased slightly.
|Hamilton test (self administration test measuring anxiety)||4.4/4.7||5.7/4.0|
Learning Disabilities And Behavior Problems
|Gilmor’s meta-analysis is based on a study of 225 children with learning and communication difficulties.
This analysis shows that the Tomatis listening sessions have a significant impact in the following areas: language,
cognitive and psychomotor development, social and personal behavior.
|Personal and social
|Etude Wilson (Hôpital universitaire de North Shore - Université de Cornell, New-York)||Test||TOMATIS / Control|
|Wilson studied 26 children suffering from a language disorder. Eighteen (18) children received Tomatis
listening sessions and 8 were assigned to the control
The results show progress for the Tomatis group in the following areas: communication, openness of hearing and ability to reproduce sound.

|Study 1 and 2 Brickwall House Institute|
(East Sussex, England)
|Brickwall studied 47 dyslexic children suffering from a delay in reading of 4/5 years. Twenty-four (24) of these children underwent Tomatis listening sessions. The remaining 23 children were assigned to the control group.
The results show a significant difference in favor of the
Tomatis group in reading ability and expression.
