Summary
This chapter describes a block diagram based network approach for construction of acoustic models of duct systems from the simpler components in one dimension and three dimensions. This topic is considered early in the book, because it describes the format used in later chapters in mathematical representation of acoustic models of ductwork components and their assemblies.
