In contrast to the traditional NAH technologies, the HELS method does not seek an exact solution to the acoustic field produced by an arbitrarily shaped structure. Rather, it attempts to obtain the best approximation of an acoustic field through the expansion of certain basis functions. Therefore, it significantly simplifies the complexities of the reconstruction process, yet still enables one to acquire an understanding of the root causes of different noise and vibration problems that involve arbitrarily shaped surfaces in non-free space using far fewer measurement points than either Fourier acoustics or BEM based NAH. The examples given in this book illustrate that the HELS method may potentially become a practical and versatile tool for engineers to tackle a variety of complex noise and vibration issues in engineering applications. 410 0$aModern Acoustics and Signal Processing,$x2364-4915 606 $aAcoustical engineering 606 $aAcoustics 606 $aVibration 606 $aDynamics 606 $aDynamics 606 $aMathematical models 606 $aEngineering Acoustics$3https://scigraph.springernature.com/ontologies/product-market-codes/T16000 606 $aAcoustics$3https://scigraph.springernature.com/ontologies/product-market-codes/P21069 606 $aVibration, Dynamical Systems, Control$3https://scigraph.springernature.com/ontologies/product-market-codes/T15036 606 $aMathematical Modeling and Industrial Mathematics$3https://scigraph.springernature.com/ontologies/product-market-codes/M14068 615 0$aAcoustical engineering. 615 0$aAcoustics. 615 0$aVibration. 615 0$aDynamics. 615 0$aDynamics. 615 0$aMathematical models. 615 14$aEngineering Acoustics. 615 24$aAcoustics. 615 24$aVibration, Dynamical Systems, Control. 615 24$aMathematical Modeling and Industrial Mathematics. 676 $a003.3 676 $a534 676 $a620 676 $a620.2 700 $aWu$b Sean F$4aut$4http://id.loc.gov/vocabulary/relators/aut$0720963 906 $aBOOK 912 $a9910299662003321 996 $aThe Helmholtz Equation Least Squares Method$92507745 997 $aUNINA
