In Sound Propagation: An Impedance Based Approach, Professor
Yang-Hann Kim introduces acoustics and sound fields by using the
concept of impedance. Kim starts with vibrations and waves,
demonstrating how vibration can be envisaged as a kind of wave,
mathematically and physically. One-dimensional waves are used to
convey the fundamental concepts. Readers can then understand wave
propagation in terms of characteristic and driving point impedance.
The essential measures for acoustic waves, such as dB scale, octave
scale, acoustic pressure, energy, and intensity, are explained.
These measures are all realized by one-dimensional examples, which
provide mathematically simplest but clear enough physical insights.
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 in a
unified way, by seeing the changes of waves due to spatially
distributed impedance. Lastly, Kim covers sound in closed space,
which is considered to be a space that is surrounded by spatially
distributed impedance, and introduces two spaces: acoustically
large and small space. The bulk of the book is concerned with
introducing core fundamental concepts, but the appendices are
included as the essentials as well to cover other important topics
to extend learning. * Offers a less mathematically-intensive means
to understand the subject matter * Provides an excellent launching
point for more advanced study or for review of the basics * Based
on classroom tested materials developed over the course of two
decades * Companion site for readers, containing animations and
MATLAB code downloads * Videos and impedance data available from
the author's website * Presentation slides available for instructor
use Sound Propagation is geared towards graduate students and
advanced undergraduates in acoustics, audio engineering, and noise
control engineering. Practicing engineers and researchers in audio
engineering and noise control, or students in engineering and
physics disciplines, who want to gain an understanding of sound and
vibration concepts, will also find the book to be a helpful
resource.
