ABSTRACT
Chapter 3 concludes the introduction to physical acoustics, describing resonance, sound propagation, and signal processing. The chapter begins by examining sound production in the real world and includes a discussion of how objects vibrate to produce sound waves. The chapter then considers how sound spreads out, or propagates, from the sound source and how it interacts with other objects in the environment, including reflection and diffraction. Finally, the chapter considers the ways in which sounds, or electronic representations of sounds, can be manipulated to change their characteristics, for example using filters.>
