Propagation of Sound in Porous Media: Modelling Sound Absorbing Materials 2e
Université du Maine, France

“The first edition of this book is considered the bible of this topic… Suffice it to say that there is no other published treatise that approaches the depth of treatment offered by this book. The coverage is the state of the published art, while the added contents cover the new known developments in the field.” – Haisam Osman, Technology Development, Manager, United Launch Alliance.
This long-awaited second edition of a respected text from world leaders in the field of acoustic materials covers the state of the art with a depth of treatment unrivalled elsewhere. Allard and Atalla employ a logical and progressive approach that leads to a thorough understanding of porous material modelling.
The first edition introduced the basic theory of acoustics and the related techniques. Research and development in sound absorption has however progressed significantly since then, and the models and methods described, at the time highly technical and specialized, have since become main stream. In this second edition, several original topics have been revisited and practical prediction methods and industrial applications have been added that increase the breadth of its appeal to both academics and practising engineers. New chapters have also been added on numerical modeling in both low (finite element) and high frequency (transfer matrix method).
Collating ‘must-have’ information for engineers working in sound and vibration, Propagation of Sound in Porous Media, Second Edition offers an indisputable reference to a diverse audience; including graduate students and academics in mechanical & civil engineering, acoustics and noise control, as well as practising mechanical, chemical and materials engineers in the automotive, rail, aerospace, building and civil industries.

Includes practical examples, with physical discussion of the results
Effectively Construct Integral Formulations Suitable for Numerical Implementation
Finite Element and Boundary Methods in Structural Acoustics and Vibration provides a unique and in-depth presentation of the finite element method (FEM) and the boundary element method (BEM) in structural acoustics and vibrations. It illustrates the principles using a logical and progressive methodology which leads to a thorough understanding of their physical and mathematical principles and their implementation to solve a wide range of problems in structural acoustics and vibration.
Addresses Typical Acoustics, Electrodynamics, and Poroelasticity Problems
It is written for final-year undergraduate and graduate students, and also for engineers and scientists in research and practice who want to understand the principles and use of the FEM and the BEM in structural acoustics and vibrations. It is also useful for researchers and software engineers developing FEM/BEM tools in structural acoustics and vibration.
Reviews current computational methods in acoustics and vibrations with an emphasis on their frequency domains of applications, limitations, and advantages;
Presents the basic equations governing linear acoustics, vibrations, and poroelasticity;
Introduces the fundamental concepts of the FEM and the BEM in acoustics;
Covers direct, indirect, and variational formulations in depth and their implementation and use are illustrated using various acoustic radiation and scattering problems;
Addresses the exterior coupled structural–acoustics problem and presents several practical examples to demonstrate the use of coupled FEM/BEM tools, and more.
Finite Element and Boundary Methods in Structural Acoustics and Vibration utilizes authors with extensive experience in developing FEM- and BEM-based formulations and codes and can assist you in effectively solving structural acoustics and vibration problems. The content and methodology have been thoroughly class tested with graduate students at University of Sherbrooke for over ten years.
