Acoustic Modeling

This book provides the only comprehensive source on how to translate our physical understanding of sound in the sea into mathematical formulas solvable by computers. The book includes practical guidelines for scientists and mathematicians needing to select and use the models, and shows them how the behaviour of sound can be modeled in a complex environment.

SWAM (Synchronous Waves Acoustic Modeling) is a new-generation, sophisticated proprietary technology that enables musicians, performers, and composers to overcome the classic limitations of traditional samplers. Conceived by Stefano Lucato and developed in collaboration with Emanuele Parravicini, the SWAM engine combines concepts of Physical Modeling and Behavioral Modeling with the Multi-Vector/Phase-Synchronous Sample-Morphing technique.

String Studio VS-2 is a string modeling synthesizer plug-in that swaps the traditional oscillator sound source for a string. With its picks, bows, hammers, fingers, frets, dampers, and soundboards, it is a unique blend of acoustic modeling and regular synth-control features—you won’t believe how crazy you can go with a simple string.

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.
