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.

By Guillermo Emilio Aldana-Calderon
Great book, it starts with the fundamentals and take off from there. First edition, so it needs an Errata list as a companion, but the errors are minor (obvious typos).

Another great fundamentals text
By adalogue
The author, Yang-Hann Kim, has taught at KAIST (formerly Korea Advanced Institute of Science and Technology) since 1989 and obtained a Ph.D. degree in Acoustics and Vibration from MIT (Massachusetts Institute of Technology). The text covers acoustical fundamentals along with detailed analyses of some more complicated acoustical topics, and is recommended for upper-division undergraduate or masters-level graduate students. Detailed information presented at the end of each chapter is expected to serve well as a resource for more advanced students and professionals.
In this text, the author proposes a "three-dimensional understanding" approach to define, explore, and comprehend acoustical fundamentals. These "three dimensions" are not spatial, but conceptual. They represent a coordinate system of understanding that seeks to provide a simpler and more effective route to learning. These three dimensions are as follows: basic acoustic principles, relative acoustic quantities, and relative acoustical scales. The path to comprehension in the text is broken down into five key components that constitute the five chapters. While impedance is not necessarily explored in significantly greater detail than other acoustical fundamental texts, it is emphasized throughout and ties key concepts together very well.
Each of the five chapters is divided into two sections: an overall presentation of the material and an appendix section that provides additional theory, analytical expressions, practical applications, and mathematical derivations. Each chapter includes 12-14 exercise problems, solutions are not provided. Charts, figures, and photos are heavily used in the text and provide key opportunities to enhance comprehension of the material.
Chapter 1 establishes the principles of vibration and 1-D wave propagation. Topics covered include the one-dimensional wave equation, propagation in strings, boundary conditions, reflection and transmission, and forced response. The concept of impedance is explained, along with examples of its influence on wave propagation. Examples of its influence include transmission and reflection of waves between two dissimilar strings and the coupling of wave motion into a string from a forced input. The Chapter 1 appendix discusses 1-D and 2-D damped harmonic oscillators and driving point impedance of bars, beams, membranes, and plates.
Chapter 2 moves from mechanical wave propagation to waves in fluids. The chapter begins with development of the 3-D wave equation with an emphasis on relative acoustic quantities, such as particle velocity and acoustic-level changes in pressure and density. Other acoustical parameters are also introduced, such as energy, intensity, and power. A four-page summary of human physiological mechanisms for hearing is aptly tethered with a discussion of frequency scales and bandwidths, weighting curves, loudness, and spectral decomposition. Impedance characteristics for plane and spherical waves are presented for far-field and near-field conditions. The Chapter 2 appendix presents additional mathematical details for the 3-D wave equation derivation and characteristics of multi-pole sources.
Chapter 3 applies impedance concepts from the previous two chapters to discuss wave behavior at a region of impedance change. Concepts of reflection, transmission, and incidence conditions are applied to a "flat surface of discontinuity." The author does an excellent job of presenting applications of various complexities, including mass law for limp walls, partitions with damping properties, and plates. The Chapter 3 appendix includes additional mathematical details for local reaction and layered transmission and reflection.
Chapter 4 looks at radiation, scattering, and diffraction of acoustic waves. Radiation impedances are defined for a sphere, baffled piston, and vibrating plate. Emphasis is made on how impedance mismatches influence whether or not an incident wave will diffract, scatter, refract, or reflect. Diffraction principles are applied to predicting the transmission loss of a barrier using the Fresnel number. Upward and downward refraction in cases of outdoor sound propagation are also mentioned. The Chapter 4 appendix provides information on directivity, beam patterns, application of the Kirchhoff-Helmholtz Integral Equation, and 27 pages devoted to theoretical approaches to solving barrier diffraction problems.
Chapter 5 describes acoustical characteristics in acoustically-small and acoustically-large closed spaces. For acoustically-large spaces, Sabine's Theory is used and influences of room surface impedance on the acoustic environment are explained. Transitions between the direct, reverberant, and diffuse field are defined along with room modal response and modal density. For acoustically small spaces, the concepts of acoustical compliance and inertance are illustrated by a classic Helmholtz resonator. The Helmholtz resonator components are also described in terms of individual impedances: radiation impedance, neck impedance (inertance), and cavity impedance (compliance). Duct acoustics and horns are also discussed. The Chapter 5 appendix describes surface impedance measurement methods, additional approaches for calculating reverberation time (Eyring, Millington, and Fitzroy), and 12 pages are devoted to the analysis of Helmholtz resonator array panels.
In summary, the text covers all of the topics one would expect to find in a fundamentals text, along with a few pleasant surprises. Frequent tie-ins to impedance and solid relations between acoustical parameters aid in comprehension of the material.
