The book is devoted to the very basis of acoustics and vibro-acoustics. The physics of the phenomena, the analytical methods and the modern numerical techniques are presented in a concise form. Many examples illustrate the fundamental problems and predictions (analytic or numerical) and are often compared to experiments. Some emphasis is put on the mathematical tools required by rigorous theory and reliable prediction methods.

Paul Filippi

Paul Filippi is a Directeur de Recherche at the CNRS (Centre National de la Recherche Scientifique) in Marseille and an editorial board memeber for the Journal of Sound and Vibration. He has been teaching courses in Acoustics in France since the early seventies, besides having studied and taught in the U.S. He received a degree in Physics in 1958, at the Université de Provence, in Marseille. He started working on Acoustics and Vibrations in 1959 as a Stagiaire de Recherche at the Centre de Recherche Scientifique Industrielle et Maritime in Marseille, a laboratory depending on theCentre National de le Recherche Scientifique. He obtained his Doctorate of Sciences degree (the highest national university diploma in France) in 1968. He was in charge of the Diplôme d’Etude Approfondies d’Acoustique at the Université de la Méditerranée from 1986 to 1995. He is now Directeur de Recherche at the Laboratoire de Mécanique et d’Acoustique (CNRS) in Marseille.

Aime Bergassoli

Aimé Bergassoli has been teaching courses in Acoustics in France since the early seventies, besides having studied and taught in the U.S. He graduated from Ecole Saint-Cyr and then, in 1953, from Ecole Nationale Supérieure d’Electricité de Paris, one of the most well known engineering schools in France. He entered the Laboratoire de Mécanique et d’Acoustique (CNRS) in Marseille in 1964 as a Research Engineer and retired in 1983. He worked on propagation and diffraction problems related to environmental Acoustics and on guided waves phenomena related to building Acoustics.
