Laboratoire d’Acoustique de l’Université du MaineLAUM - UMR 6613

Founded in 1981, the LAUM is a joint research unit of the Université du Maine and of CNRS - UMR 6613 (section 9, Institut des sciences de l’ingénierie et des systèmes, INSIS).

The LAUM has about 110 employees including 50 full-time researchers and teacher-researchers: 16 Professors and 20 Lecturers of the Université du Maine, 6 Teacher Researchers associated with the ESEO (Angers), and 8 CNRS researchers. 13 technical and administrative personnel assist the researchers. There are currently 39 PhD students and a regular flow of non-permanent personnel (currently 7 guest professors and post-doctorates). The LAUM published 75 articles in international peer reviews in 2010.

Since 2000, it has been the leading European laboratory for publications (4th worldwide) in the 2 world-class reviews wholly dedicated to acoustics: Journal of the Acoustical Society of America and Acta Acustica. LAUM has been graded A+ by AERES (2011).

The research activities are divided among three teams: the research of the Acoustics and mechanics of materials team focuses on modeling acoustic propagation in complex media (inhomogeneous, diphasic, multilayer, with property gradients, etc.), the development of analytical and numerical methods and the relevant metrology. The research performed by the Acoustic transducers team focuses on modelling and the experimental study of "acoustic" transducers (microphones and loudspeakers, thermoacoustic systems), and on developing the related signal processing. The research performed by the VAGUE team (Vibrations, guided acoustics and flows) concerns the resolution of problems related to the radiation of sound sources, whether desired (musical instruments) or not (aeronautics, radiation from vibrating structures, etc.).


In this project, the LAUM is involved in the characterization of resonator, the design and manufacturing of the final metamaterials for the absorption of audible sound at low frequency.
