Léonie Maignan
Acoustics Intern
Léonie is completing a 6-month internship as the final stage of her master’s degree in acoustics and musicology (Aix-Marseille University). She is leading a research project to develop a testing bench for our products, allowing for a deeper analysis of their vibratory characteristics — a tool that will help us further improve the reliability and quality of our devices.

The project was born in 2015 during a workshop for the ITER master’s program, held on a scenic lookout overlooking Lake Paladru. Due to various constraints (a protected outdoor area), the students proposed listening to sound using the body itself.
Later on, two social science laboratories — PACTE and CRESSON — took over the project to further research body-based listening and develop the first proof of concept.
In addition to the audio devices, we can provide sound content tailored to your needs. We know how to make all types of audio clear and engaging — vocals, songs, narration, sound effects, music, and more.
We also offer a 2-year warranty on our products and provide guidance on the best ways to use the Losonnante audio devices.
Reconnect with sound through the body to enchant your visitor experience!
Our audio devices are designed for public spaces looking to enhance their heritage by offering visitors a powerful, multi-sensory experience.
Work with us



At Losonnante, we are constantly striving to improve our products. From user experience, acoustics, and mechanics to electronics and app development — our research spans a wide range of complementary fields. We design innovative products using bone conduction technology.
We have a deep understanding of what listeners expect from our devices and which types of content will have the greatest impact on your bone conduction listening project.
That’s why we encourage our clients to create tailored content. If needed, our sound production manager can handle the entire creation process based on your intentions:
Scriptwriting
Voice casting
Recording with voice actors
Translations and multilingual recordings
Post-production
Sound design (including optional binaural audio), with the integration of various elements for a sensitive and immersive 360° listening experience
Do you have a specific project? An installation that requires custom development? Our research and development team — made up of experts in electronics, acoustics, and software engineering — can create a configuration that meets your expectations and fits the constraints of your exhibition spaces.
Our unmatched expertise in audio and in the transmission of sound vibrations through solids allows us to deliver spectacular and unique experiences. We start from your intentions and needs to define and bring to life a one-of-a-kind concept.
