Summary
Acoustic design of ductworks such as fluid machinery intake and exhaust systems usually requires a large number of iterations for concept validation and prototype development. The network approach is ideally suited for this purpose, but systematic search and optimization methods are indispensable for quick and efficient progress. The last chapter, Chapter 13, discusses the acceleration of iterative design calculations and handling uncertainties about model parameters. We also present an approach which brings an inverse perspective to the conventional target based acoustic design calculations.
