Engineered Materials for Acoustics: Metamaterials, Sonic Crystals and Calculated Microstructures
Abstract
For two decades, research on acoustic materials (absorbent and insulating) has largely translated into metamaterials and sonic crystals or, more generally, into engineered acoustic materials. A large number of scientific articles on these unconventional materials appear every week, even every day. While research is moving towards a more in-depth knowledge of these materials and new concepts, their applications are already numerous in several sectors of industry such as building and transport. Through all the research, it is sometimes difficult to fully define what acoustic metamaterials, sound crystals, and engineered acoustic materials really are. This presentation presents the author's personal definition of these different classes of materials, adding the class of acoustic materials with calculated microstructure, and grouping them under the family of "engineered acoustic materials". Definitions are proposed for each class and examples of applications are presented.
