Ground Meludia in a shared scientific standard.
Meludia Alliance for Auditory and Cognitive Sciences
An open working group, in service of Meludia
In practical terms, the MAACS tests Meludia’s clinical and technological choices, documents the state of the art in hearing and cognitive sciences, and observes what the solution produces in people who are fitted with hearing aids — benefits, limitations, responder profiles.
The MAACS is not a scientific committee in the institutional sense — though it is setting itself on that trajectory over time. It prepares the ecosystem in which a true scientific committee can later take shape. At this stage, it supports Meludia in its need to be grounded in a multidisciplinary scientific standard.

areas of action: test, document, measure
3
priority audiences: age-related hearing loss, cochlear implants, listening complaints without threshold shift
Hearing cannot be reduced to an audiometric threshold.
Understanding what we hear engages the cognitive system as much as the auditory system — and that is precisely what the MAACS is committed to testing, documenting, and measuring.
Test
Document
Maintain the state of the art in scientific knowledge in hearing and cognition that informs Meludia’s choices and uses. Identify areas of uncertainty.
Measure
The principles that guide how we operate
The MAACS is built on explicit commitments — not communication postures, but operating rules that apply starting today.
Clarity over comfort
Internal disagreements are open. Hypotheses are identified as such. Choices without scientific consensus are explicitly owned — never dressed up as certainties.
Transparency on conflicts of interest
Members of Circle 1 are paid by Meludia. The MAACS makes this information visible — it appears in any external communication bearing a MAACS signature.
True multidisciplinarity
Audiology, speech therapy, hearing aid fitting, ENT, neuropsychology, clinical methodologies. No discipline takes precedence over the others — the relevance of the shared topic takes precedence over individual ambitions.
Regulatory rigor
Meludia’s TPI is a Class I medical device. The MAACS does not diagnose, does not prescribe, and does not claim any effectiveness beyond what the literature and available studies allow us to state.
A three-circle structure of expertise
The MAACS is built on explicit commitments — not communication postures, but operating rules that apply starting today.
Each circle has its own entry mode, level of commitment, and type of contribution. The structure is designed to grow without losing rigor.
Circle 1 - Internal & operational
Made up of:
- Didier Ghenassia: Speech therapy, CEO Meludia
- Bastien Sannac Cunningham: Engineering, Innovation
- Vincent Chaintrier: Musicology, Expert patient
- Élodie Lacore: Clinical speech therapy
- Thibault Dumoulin: Hearing aid fitting, Teacher
- Azal Le Bagousse: Psychoacoustics, Neurosciences

Circle 3 - Institutional & partners
ENT departments, audiology centers, sensory geriatrics, hearing aid schools, foundations, learned societies, patient and caregiver associations. Circle 3 is where the MAACS steps outside itself to measure what it produces in the real world.

Additional observational study
MAACS — Circle 1 Meludia
A study led directly by the MAACS, complementary to the France 2030 program. It aims to observe the effects of Meludia Audition on patient profiles that complement those in the main multicenter protocol. Its design is currently underway within Circle 1, with methodological support planned via Circle 2 once it is established.

France 2030 multicenter study - Meludia Audition Aging Well
Meludia Audition Aging Well consortium · Independent CRO · MAACS (Measurement stream)
A double-blind multicenter clinical study with a crossover design, conducted under the aegis of the Meludia Audition Aging Well consortium, in response to the France 2030 call for projects on the clinical and medico-economic demonstration of digital medical devices in support of aging well. The methodology is led by an independent CRO specialized in digital. Recruitment and execution are coordinated with the consortium’s partners. The first interim readouts are expected within the next 18 months.

Study of non-music-related cognitive benefits (concentration, creativity, problem-solving) following the use of meludia with children in primary school
This study examines the effects of perceptual training with Meludia on general cognitive dimensions — concentration, creativity, problem-solving — in primary school children, independently of musical skill itself. It falls within the field of research on cognitive transfer from auditory training.

Observational pilot study — Feasibility and clinical impact of the TPI in real-world conditions
Conducted between February and April 2025 in partnership with the Acuitis network, this pilot study aimed to demonstrate the technical and clinical feasibility of the TPI (Test de Perception des Intensités) in real-world conditions. It assessed patient and hearing care professional satisfaction, as well as the relevance of the results for fitting hearing aids. Key results: 94% of patients completed their 3-TPI cycle before the 2nd appointment; 95% of hearing care professionals consider the results useful; 87% changed settings based on the 1st cycle; an average gain of 37% in comfort zones between the 1st and 2nd cycle. A scientific article is currently being submitted to a peer-reviewed journal.

Study of the benefits of self-guided training with meludia for cochlear implant users on music perception and engagement in listening to music
A study aiming to measure the effects of self-guided perceptual training with Meludia in cochlear implant users, on two dimensions: music perception and long-term motivation to listen to music. It extends published work on online music training for this population.

The Meludia platform as a tool to assess music perception in pediatric and adult cochlear implant users
La Paz University Hospital, Madrid
Publication in European Archives of Oto-Rhino-Laryngology
This study assesses the relevance of the Meludia platform as a standardized tool for measuring music perception, distinguishing between pediatric and adult cochlear implant patient profiles. It examines Meludia’s ability to discriminate perception levels across several acoustic cues (intensity, pitch, timbre, rhythm) in a clinical ENT setting.

This study examines the use of Meludia as an online music training program adapted for cochlear implant users. It evaluates how well the perception exercises (pitch, timbre, rhythm) match the specific abilities of this population and how they can be integrated into a post-implant follow-up pathway.

A randomized controlled crossover study on the impact of online music training on pitch and timbre perception in cochlear implant users
University of California – San Francisco (UCSF)
Publication in Journal of the Association for Research in Otolaryngology
This randomized controlled crossover study examines the impact of an online music training program (Meludia) on pitch and timbre perception in adult cochlear implant users. It evaluates the effects of structured perceptual training on these two acoustic cues, which are particularly difficult for CI users to process, and helps establish proof of concept for self-guided perceptual training in this population.
