From Wave Comparison to Acoustic Product Design
This presentation serves as an introductory course in technical acoustics. Dr. Anne de Jong, M.Sc., first covers the physical fundamentals: sound pressure, third-octave bands, psychoacoustics (loudness in phons, A-weighting), and the derivation of the wave equation. He then compares numerical simulation methods (FEM versus BEM). The section on sound measurements covers microphone types, acoustic intensity, and source localization (arrays, PNAH, IBEM). Finally, the author presents design rules for products (vibration isolation, absorption foam, the mass law, and resonant absorbers) and nonlinear acoustics (such as levitation and streaming).
