This paper presents the pedagogical approach, the results, constraints, contributions and limits of a multidisciplinary student project. The regional program Research Training Innovation Western Creative Industries (RFI OIC) of the Pays de Loire region proposed in 2018 a multidisciplinary student project to the Universities of Nantes, Angers and Le Mans. At Le Mans, the project brought together historians, computer scientists and acousticians from the university and students from the sound design master of the School of Art and Design (ESAD TALM) in association with the city. A first project consisted of a sound path with a headphones. The second, which concerned the acousticians, consisted of developing systems of diffusion outside, original if possible. In connection with the ESAD, two students from the National School of Engineers of Le Mans have devoted their 5th year project to this subject. In particular, they developed a stereo pair of vibrating panels to broadcast battle sounds as well as simple directional sources, before putting these prototypes and professional systems in situ. A presentation of the devices was made in front of the elected officials of the city one year after the project beginning and was apreciated. This project has been very enriching for engineering students in terms of collaboration with students and teachers of other disciplines. However, it was quite poor from a scientific point of view, the share of management and technology being essential. He thus highlighted some difficulties in this collaboration and the gap between the expectations of the sponsors and the potentialities of a student project. The project is being continued this year with more reasonable expectations, but with the ambition to promote student work in the city's cultural policy.
