Textbook in PDF format This book derives physical models from basic principles, studies the effect of equivalent models on the dynamic characteristics of phononic crystals and acoustic metamaterials, and analyzes the physical mechanisms behind vibration and noise reduction. It first summarizes the research status of vibration and noise reduction, and research progress in phononic crystals and acoustic metamaterials. Based on this, one-dimensional periodic beam, two-dimensional thin plate with circular hole, and corresponding gradient structures are introduced, and their dynamic characteristics are discussed in detail. Basic Theories of Acoustic Metamaterials for Solving the Dynamic Equivalent Inverse Problem Theoretical Model for Solving the Inverse-Problem of Dynamic Equivalent Media of Periodic Rod-Beam Structures Theoretical Model for Solving the Inverse Problems of Dynamic Equivalent Media of Periodic Plate Structures Study on the Vibration Characteristics of a Gradient Rod Based on the Theoretical Model for Solving the Inverse Problem of the Dynamic Equivalent Medium Study on the Low-Frequency Bandgap Mechanism of a Multilayer Slit-Tube Structure Based on the Acoustic-Electric Analogical Equivalent Model
