An Impedance Based Approach

¥ 10,027 (tax included)

Description

Delivers the key essentials of acoustics in an approachable manner, allowing students and engineers to easily understand this interdisciplinary topic

Kim introduces acoustics and sound fields by using the important concept of impedance, making the subject of acoustics more accessible to both students and engineers. Kim starts with vibrations and waves, demonstrating how vibration can be envisaged as a kind of wave, mathematically and physically, before moving onto the study of acoustic waves. One-dimensional waves are introduced since they are the simplest to understand while demonstrating the same mathematical and physical characteristics that all general waves have. Readers will then be able to determine a means of finding solutions of acoustic wave equations. Kim then moves on to explaining waves on a flat surface of discontinuity, demonstrating how propagation characteristics of waves change in space when there is a distributed impedance mismatch. Next is a chapter on radiation, scattering, and diffraction, where Kim shows how these topics can be explained with one of two approaches: finding the solutions that satisfy a linear acoustic wave equation and boundary condition or use the integral equations. Lastly, Kim covers sound in closed space. The bulk of the book is concerned with introducing core fundamental concepts, but an appendix is included as well to cover other important topics to extend learning.
