We’re back at the ICNM World Congress – And this year, we’re taking the stage

Pierre Griffoin — Mon, 15 Jun 2026 13:01:09 +0000

For the second year in a row, Holopsonie will be present at the ICNM World Congress in Paris on July 10–11, 2026. We are truly honored to have been selected again to share our work with an international audience of practitioners and researchers committed to natural and integrative approaches to health.

Each year, the quality of the presentations and the caliber of the attendees make this congress one of the most inspiring events in our field. Being invited back is both a recognition and a responsibility we take very seriously.

This year marks another important milestone for us: it is the first time we will be delivering a sponsored lecture. We have been granted a dedicated 20-minute slot on Saturday morning, where we will present our latest clinical observations on how personalized audio-cerebral training can support emotional regulation and cognitive function. You can find us in the official program on icnm.eu.

As part of the selection process, we submitted a detailed abstract outlining our approach and results. You can download it here (PDF).

Beyond the formal presentation, what makes this congress special are the human encounters it creates. Last year, we had a particularly touching moment with Samuel, a fellow exhibitor who was presenting his own products at the event. For months, he had been struggling with severe sleep disorders. During a conversation, we offered him the use of a Holopsonie audio brain training setup — simply a portable player and headphones — to listen before going to bed.

That same night, Samuel experienced something he hadn’t had in a long time: he slept like a baby. Deeply and peacefully. He continued using the training over the following days and reported a clear and lasting improvement in his sleep quality. Moments like these remind us why we do what we do — seeing how this gentle yet powerful method can bring real relief, even in the middle of a busy professional event.

We look forward to meeting many of you in Paris. Whether you are already familiar with Holopsonie or simply curious about audio-cerebral training, come and say hello. We will be happy to share our latest findings, answer your questions, and show you how this approach can be integrated into your practice.

See you at the ICNM World Congress!

How Holopsonie draws inspiration from and sets itself apart from Tomatis’s approach

Pierre Griffoin — Thu, 24 Apr 2025 12:17:13 +0000

If you’re familiar with Alfred Tomatis, pioneer of sound therapy with Audio-Psycho-Phonology (APP), you may already have explored his methods.

Holopsonie, an approach derived from his work, has been relaunched with contemporary adjustments and modernized tools.

In this article, find out more about this exciting development… and why you might want to try it out with our short, no-obligation rental formula.

Alfred Tomatis and the beginnings of sound therapy

Alfred Tomatis (1920-2001), a French ENT doctor, was a pioneer in the study of the influence of sound on the brain and behavior. He developed APP (Audio-Psycho-Phonology), a method using filtered music according to standardized protocols.

Its aim is to promote the overall development of the individual, by acting on cognitive, emotional, psychomotor and relational dimensions. In particular, the Tomatis Method aims to improve attention, memory, language, coordination, posture and even voice, by working on brain plasticity through listening. It has been used in contexts as varied as school learning, neurodevelopmental disorders, psychosomatic pathologies and support for artists and therapists.

The Tomatis reference protocol is based on three listening cycles, each consisting of two sessions per day for 10 days, spaced several weeks apart. This standard protocol represents around 60 hours of listening, and requires rigorous professional guidance.

Tomatis’s research has influenced many modern approaches, including Holopsonie.

Guy Berard’s influence and the foundations of Holopsonie

Holopsonie was born in Amiens in 1985, thanks to Dominique Bourdin and Jean Bouchet. Both were inspired by the work of Tomatis, but above all by that of Guy Berard (1916-2014), one of his students. In the 90s, Berard developed AIT (Auditory Integration Training). While practicing as a general practitioner, Dominique Bourdin was able to observe the remarkable beneficial effect of this method on a patient, while the local gazette “Le Courrier Picard” had reported with reference to the local manufacture of the equipment used: ” The machine to heal depression is manufactured in Amiens”

“.

Bérard identified hypersensitivity to frequencies between 1500 and 8000 Hz in certain people suffering from depression or autism. He showed that auditory rebalancing could reduce or even eliminate certain symptoms. His approach gained notoriety in the United States with the publication of the book Sound of a Miracle, in which Annabel Stehli recounts the spectacular improvement of her autistic daughter thanks to AIT.

Jean Bouchet, who collaborated successively with Tomatis, Bérard and Bourdin, played a central role in the integration of these approaches within Holopsonie.

The beginnings in Amiens and the end of the project

Between 1985 and the early 2000s, Bourdin and Bouchet developed and manufactured the first Holopsones devices. Their aim: to use sound to reharmonize body and mind. Production was discontinued almost 15 years ago, however, leaving the approach dormant… until today.

The rebirth of Holopsonie by Holotech Industry

In 2023, Pierre Griffoin relaunched Holopsonie by founding Holotech Industry in Lyon. Building on the legacy of Tomatis, Bérard, Bourdin and Bouchet, he modernized the approach and equipment.

Major developments include:

The music is personalized according to individual auditory perceptions, thanks to a listening test.
Sessions are short: 1 or 2 a day for 5 to 10 days.
The devices can be used independently at home.
The method is available for short-term rental, for a no-obligation trial.

What sets modern Holopsonia apart

In contrast to conventional approaches based on generic music and long processing times, Holotech Industry’s Holopsonie is characterized by a :

Personalized: each protocol is fine-tuned to your individual hearing profile, based on a listening test.
Accessible: users can enjoy the experience at home, at their own pace and independently, using an audiophile player and appropriate headphones.
Concise: 6 to 10 sessions spread over 3 to 10 days are generally enough to feel the first effects.

But Holopsonie’s originality lies not only in the flexibility of its protocol. It also relies on a finesse of analysis and sound processing that is far more precise than in previous approaches:

Each ear is tested and treated independently, taking into account their natural asymmetry.
Auditory sensitivity is measured frequency by frequency, on 15 to 25 points divided into twelfths of an octave, offering a much finer reading than the quarter or third octaves generally used.
Sound treatment is customized to mirror the listening experience, attenuating areas of hypersensitivity and stimulating areas of hyposensitivity.
Sound modulation causes a bass/treble switch, prompting the brain to “reconstitute” the original signal, stimulating auditory and emotional plasticity.

These technological and therapeutic choices enable a more targeted, faster and often deeper impact on cognitive, sensory and emotional levels.

Why try Holotech Industry’s Holopsones?

The new Holopsones combine scientific rigor with ease of use. Many users report significant benefits, such as :

Reduced stress,
Improved concentration,
Overall well-being.

Our short rental formula lets you try out the method at a lower cost. It’s a great way to find out more without hurrying.

An enriched, accessible approach to sound

Holopsonie is a continuation of the research carried out by Tomatis and Bérard, enriched by Bourdin and Bouchet, and relaunched today by Holotech Industry. More accessible, more personalized, it adapts to your pace of life.

Holopsonie: a listening puzzle

Pierre Griffoin — Thu, 24 Apr 2025 12:14:47 +0000

🎧 Holopsonie: a listening puzzle

A stimulating auditory puzzle at the heart of Holopsonie’s effective auditory training.

Holopsonie is more than just “playing music”. It’s a structured, subtle method designed to stimulate the brain using a simple, powerful principle: to present it with an auditory puzzle.

But what do we mean by the “listening puzzle”? And why is this idea at the heart of Holopsonie’s effectiveness?

💡 Listening that stimulates, not just lulls

Unlike other approaches to relaxation through music, Holopsonie does not simply seek to “soothe” by playing pleasant sounds. It activly modifies the music to introduce a form of imbalance into the auditory signal… and force the brain to readjust.

This voluntary imbalance acts like a sound puzzle : it stimulates hyper or hypo sensitive areas, prompting the brain to compensate for them.

🧠 Result: gentle, targeted stimulation of self-regulation mechanisms.

⚙️ How does it work?

The puzzle effect is based on three fundamental elements of the method:

An individual listening test
This allows us to map the auditory peaks (hypersensitivity) and valleys (hyposensitivity) specific to each person.
An occulting modification of music
The frequencies heard by the right or left ear are filtered to allow only high-pitched or low-pitched sounds to pass through.
👉 In other words, the music is modified so that only part of the spectrum can be heard by each ear at any given time .
Targeted music modification
Frequencies are filtered or accentuated according to the needs indicated by the test.
👉 In concrete terms, the music is modified to reveal to the ear what it no longer hears well (hollows), by increasing under-perceived frequencies, and conversely, to attenuate what it perceives excessively (peaks).
This fine-tuned action creates a puzzle effect: the auditory system is confronted with its own imbalances, reflected in the music it receives. This forces the brain to adapt, readjusting its perceptual thresholds to restore harmony.
Repeated sessions
The brain is exposed to this “puzzle listening” twice a day, for several days.
This regular stimulation is essential to trigger a process of self-organization.

💡 We’ve noticed that the stranger, more discontinuous or “incomplete” the music seems, the more the brain is prompted to restore coherence. This adaptive work is at the heart of the transformation process. Numerous parameters are available to choose and structure the level of stimulation, like progressing from a 10-piece puzzle to a 1000-piece jigsaw.

🔄 A sensory feedback loop

Each Holopsonie session acts as an auditory feedback loop:

The brain perceives modified sound information;
It tries to fill the gaps or correct the excesses;
This attempt stimulates the brain areas concerned (auditory, attentional, emotional);
This gradually leads to a functional rebalancing.

In other words, listening becomespersonalized brain training, non-invasive and without side effects.

🌐 A global, non-verbal, effective method

By stimulating active listening, Holopsonie acts indirectly on :

concentration and attention,
emotional management,
memory,
stress and anxiety,
and all the areas where the brain is involved…

And all without conscious effort, suggestion or verbalization.

This non-directive approach enables people to access wellness through their own resources, simply by reconnecting to their inner listening skills.

🧩 Holopsonie, a benevolent puzzle of oneself

The image of a jigsaw puzzle is perfectly suited to describe what this method proposes: a readjustment of subtle imbalances, but also a space for spontaneous adjustment.

Because it doesn’t force anything, Holopsonie can accompany a wide range of audiences, from hypersensitive young children to overworked adults or senior citizens looking for anchoring.

📌 Key to retain :

Holopsonie does not cure; it activates.

It does not propose; it trains.

It does not analyze; it fine-tunes.

✨ And it is within this rebalancing effort that holistic well-being arises…
