Book Description
" ... This survey is one of a series of NASA publications that include information of interest to the non-aerospace community. In this survey, the major revival and expansion of acoustic technology that took place in the middle of this century has been reviewed. ... The information in this document is based on a comprehensive examination of the literature available on the subject. The reference material is concerned primarily with investigations of the mechanisms by which noise is generated, the propagation of noise by spacecraft boosters, the origin of noise generated by compressors in aircraft turbojet engines, and the subjective effects of noise on humans. Because many of these investigations are still in progress, the extent to which they are treated is limited in some cases. It is hoped, however, that the information presented here will stimulate interest in acoustics and the control of noise, and will guide interested persons to sources of specific information in the literature presently available."--Foreword.
Numerical Ocean Acoustic Propagation in Three Dimensions
Author: Ding LeePublisher: World Scientific
ISBN: 9789810223038
Category : Science
Languages : en
Pages : 224
Book Description
This book introduces a comprehensive mathematical formulation of the three-dimensional ocean acoustic propagation problem by means of functional and operator splitting techniques in conjunction with rational function approximations. It presents various numerical solutions of the model equation such as finite difference, alternating direction and preconditioning. The detailed analysis of the concept of 3D, N x 2D and 2D problems is very useful not only mathematically and physically, but also computationally. The inclusion of a complete detailed listing of proven computer codes which have been in use by a number of universities and research organizations worldwide makes this book a valuable reference source. Advanced knowledge of numerical methods, applied mathematics and ocean acoustics is not required to understand this book. It is oriented toward graduate students and research scientists to use for research and application purposes.
NASA Technical Memorandum
Author: Handbook Of Contemporary Acoustics And Its Applications
Author: Jun-ru WuPublisher: World Scientific
ISBN: 9814651303
Category : Technology & Engineering
Languages : en
Pages : 467
Book Description
Modern acoustics has blossomed rapidly in the past decades. Beginning as a branch off from the classical physics, modern acoustics has become an interdisciplinary science that has exceeded the boundaries of its origins. As a result, the demand for graduate students, professionals and specialists who need to master the knowledge of acoustics is growing quickly. The primary goal of this publication is to meet this urgent need by providing an updated, comprehensive reference book that educates readers on both fundamental concepts as well as their broader applications in the fast-moving technological world. The Handbook of Contemporary Acoustics and Its Applications systematically covers the theoretical principle and analytical methodology of generation, propagation and reception of acoustic waves in an ideal (inviscid) and non-ideal fluid media. The topics include the transduction, radiation, scattering, diffraction and reception of the acoustic wave. It also discusses the acoustic field in a duct/pipe, waveguide and cavity, the wave propagation in the multi-layers, nonlinear finite amplitude wave propagation and the mechanisms of physical and biological effects and their broad modern applications such as sonoporation, targeted drug delivery, acoustic tweezers, noninvasive high intensity focused ultrasound (HIFU) surgery, as well as sonoluminscence. Readers are also provided with the fundamental mathematic background and relevant references necessary for their creative inventions and applications.This handbook is intended for senior undergraduate and graduate students, as well as specialists working in relevant fields, and may be used as a textbook in courses covering acoustics.
Fundamentals of Acoustic Field Theory and Space-Time Signal Processing
Author: Lawrence ZiomekPublisher: CRC Press
ISBN: 1000108600
Category : Technology & Engineering
Languages : en
Pages : 707
Book Description
Providing a wealth of information on fundamental topics in the areas of linear air and underwater acoustics, as well as space-time signal processing, this book provides real-world design and analysis equations. As a consequence of the interdisciplinary nature of air and underwater acoustics, the book is divided into two parts: Acoustic Field Theory and Space-Time Signal Processing. It covers the fundamentals of acoustic wave propagation as well as the fundamentals of aperture theory, array theory, and signal processing. Starting with principles and using a consistent, mainly standard notation, this book develops, in detail, basic results that are useful in a variety of air and underwater acoustic applications. Numerous figures, examples, and problems are included.
