      abstract = {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. Therefore,  different equivalent methods for different models are  proposed through theoretical analysis, modal analysis and  transmission rate analysis. Finally, a Helmholtz-type  acoustic metamaterial, i.e. a multi-layer slotted tube  acoustic metamaterial, is studied. Aiming at the  low-frequency band gap of this model, a theoretical model  for solving the inverse problem of acousto-electric  analogue equivalent is proposed, and the effect of  structural parameters on the low-frequency band gap is  studied using this equivalent model. This book closely  revolves around how to conduct equivalent research on  artificially fabricated periodic structures. The methods  and conclusions presented in this book provide a new  theoretical basis for the application of artificial woven  periodic structures in the field of low-frequency vibration  reduction and noise reduction and are also an innovation in  the discipline of vibration and noise control. This book is  suitable for undergraduate students, graduate students and  teachers in vibration and noise majors in universities, and  can also provide references for engineering and technical  personnel in related fields. .},
