Tomatis Method

Alfred Tomatis and the Electronic Ear

The company that now markets the method states that Alfred Tomatis was born in Nice in 1920 and worked as a physician specializing in the ear, nose and throat. It dates his first work in the early 1950s, when he ran acoustic laboratories at aeronautical arsenals and, by its account, noticed a link between workers' ear damage and voice problems. This became the basis for his idea of an audio-vocal loop, in which what a person can hear shapes what the voice can produce. This is the company's own account and has not been independently reviewed.

The same source dates the development of the Electronic Ear to 1955-1960 and says Tomatis submitted three laws about hearing and voice to the Academy of Sciences in Paris in 1957. It uses the word submitted, and it does not say the Academy accepted or endorsed them. A first Electronic Ear is said to have been shown at the Brussels Universal Exhibition in 1958. Bone-conduction headphones and a listening test are placed in the 1970s, and Tomatis is said to have died in December 2001.

Development after Tomatis

According to the company timeline, the analog equipment became digital between 2000 and 2005 and was renamed Tomatis Audio Pro. A portable device called Solisten was introduced for home sessions in the period 2005-2010, and an online training platform called the Tomatis Academy launched in 2017. Centers are said to exist mainly in Europe, Canada, the United States, South Africa and Japan. User and practitioner numbers on the company site are marketing figures and were not independently confirmed.

A 2000 review written by authors from a listening center that offers the method describes Tomatis as the originator of modified-music training and says that at least a dozen offshoot systems followed. The same review states that none of the offshoot systems had research to support their claims and calls for research on the method itself. Because the authors are affiliated with a provider, it is best read as an insider commentary.

Names in use

The method is called the Tomatis Method, Tomatis sound therapy, Tomatis auditory stimulation and, in the founder's own term, audio-psycho-phonology. Current providers also use the phrase Listening Training for their programs. The company describes it as a neurosensory stimulation program built on music and language, and uses the phrase aerobics for the ear. The Tomatis Effect is the name practitioners give to the proposed link between what the ear can hear and what the voice can produce.

Related terms and confusable approaches

A Cochrane review groups the Tomatis Method with auditory integration training and Samonas Sound Therapy as sound therapies in which people listen to music altered by filtering and modulation. Auditory integration training is a separate procedure with its own trials, and findings for one should not be read across to the others. The Mozart effect is a different topic again, and a review of the literature found that effects from listening to Mozart were limited to one spatial skill and lasted only minutes.

What sessions are described as involving

Providers describe a program in which a person listens to music, often Mozart, and sometimes recorded or live voice, through headphones. A device filters the sound and alternates between low and high frequencies, which the company calls electronic gating. Bone-conduction transducers are part of the headphones in some versions. The company says the aim is to train the brain to stay alert and to improve selective attention. These are provider descriptions of intent and not tested mechanisms.

Program length in studies

In trials, program length varies. The trial reported in the Cochrane review ran four blocks of three weeks over 18 weeks, and a 2024 Chinese study used two 10-day training periods totaling 30 to 40 hours of listening. An Italian open-label study had participants listen to Mozart filtered by a Tomatis-type device for two hours a day over fifteen days. The review notes that Tomatis programs are individualized and vary in length.

What providers say the method is for

The Tomatis company's timeline says the method expanded in the 1960s from voice work to emotional disorders, learning difficulties, language problems and foreign-language learning. The company site describes effects on motor skills, emotions, cognition and attention, and carries a disclaimer that the information has not been evaluated by the US Food and Drug Administration and that its products are not intended to diagnose or treat disease.

Areas that have been studied

Published studies of the method have looked at language in children with autism, autism symptom scores, sleep in women during perimenopause, and seizures, sleep and behavior in children with severe epilepsy. Whether each use is supported is addressed in the next section, and the listing here does not imply it is.

Systematic review in autism

The Cochrane review of auditory integration training and other sound therapies for autism spectrum disorders searched databases to September 2010. It included six randomized trials of auditory integration training and one of Tomatis therapy, with 182 participants aged three to 39 years. Five trials had fewer than 20 participants, allocation concealment was inadequate in all, and twenty different outcome measures were used. Meta-analysis was not possible. The authors concluded that there is no evidence that these sound therapies are effective for autism, and that the data were insufficient to show they are ineffective.

The one Tomatis trial is Corbett 2008, a randomized, double-blind, placebo-controlled crossover study of language in children with autism. Most children improved in language over the study, but the change did not appear related to the treatment condition, and the percent change for placebo was larger than for treatment in one group. The review notes that the groups differed at baseline and that behavioral outcomes were not reported.

Later and smaller studies

A 2024 study of children aged 3 to 8 with autism paired children by age, sex and severity and randomly assigned them within pairs. Fifteen children per group completed the cross-sectional comparison, and the authors reported greater symptom improvement after Tomatis training than with the same music on ordinary headphones. The longitudinal part had no control group and lost 32 of 57 children. One author is employed by a company in the field, and the authors call for larger samples and direct brain measures.

An Egyptian open-label randomized trial of 146 children compared hyperbaric oxygen, Tomatis sound therapy, both, and no intervention, and reported the best autism rating scale results for the combination. Because it was open label and the abstract does not describe blinded assessment, its findings are weak evidence. A 2026 retrospective record review of 120 perimenopausal women compared Tomatis music with routine nursing and standard music, and reported the largest sleep score changes in the Tomatis group, though groups were formed by prior treatment and outcomes were self-reported.

Other conditions and overall picture

An 11-patient open-label study of children with drug-resistant epileptic encephalopathy reported that five had at least a 50 percent reduction in seizures during fifteen days of Tomatis-style listening. There was no control group, and the finding cannot be attributed to the filtering. A 1999 review of alternative treatments for attention-deficit/hyperactivity disorder stated that there was no scientific evidence to support sound training of the Tomatis type as a treatment for that condition. This page found no systematic review of the method for dyslexia or learning disorders.

Reported adverse effects and hearing

The Cochrane review reports for auditory integration training that minor physical complaints occurred in both groups and that no study reported specific deterioration on a standardized behavior test. It adds that care must be taken not to risk hearing loss from sound delivered through headphones. The Tomatis trial in the review did not report adverse events in detail. The 2026 perimenopause record review graded all 37 Tomatis participants as grade 1, meaning no reported side effects, though it did not describe how events were collected.

Cost, time and care boundaries

Programs involve many hours of listening over weeks or months. The Cochrane review gives cost figures only for auditory integration training, of about 1000 US dollars or more, and no cost for Tomatis programs was found in the sources reviewed here. Because the review judged the evidence for sound therapies in autism insufficient, families weighing the method alongside therapies with stronger evidence may face costs in time and money. The review's authors describe such treatment as experimental, and this page is not a substitute for assessment by a qualified clinician.

No independent professional register, accreditation body or training standard for Tomatis practitioners was found in the free sources reviewed. The company lists certification and an online academy, but its requirements could not be verified, so claims of accreditation should be checked with the provider.
