Propagation of Sound in Porous Media: Modelling Sound Absorbing Materials 2e

Jean-Francois Allard, Université le Mans, France and Noureddine Atalla, Université de Sherbrooke, QC, Canada
Jean-Francois Allard was a full professor at the university of Le Mans (France) since 1979, where he is now an emeritus professor. In 2008 he was awarded the M. A. Biot medal of Poromechanics from the American Society of Civil Engineers (ASCE) for his outstanding research contributions in extending Biot theory to the acoustics of air filled sound absorbing porous materials by providing models and measuring techniques for the industry. He is currently working in collaboration with the ATF laboratory (Katholieke Universiteit Leuven, Belgium) on the metrology of anisotropic porous media. He has been responsible for many contracts with car manufacturers, aircraft manufacturers, and motor manufacturers.

Noureddine Atalla is Professor of Mechanical Engineering at the Université de Sherbrooke, QC, Canada. He is internationally recognized as an expert in the field of computational vibroacoustics and acoustic materials and has published over 55 papers in peer-reviewed journals spanning different domains, including coupled fluid-structure problems, the acoustic and dynamic response of sandwich and composite structures, poroelastic and viscoelastic materials, and modeling methods for industrial structures. He has been involved in several international projects dealing with computational vibroacoustics and design of acoustic materials, working in collaboration with the US Air Force and Boeing, amongst others. He has recently been awarded an industrial chair in Aviation Acoustics in partnership with Pratt & Witney Canada, Bombardier Aerospace and Bell Helicopters Textron.
