Sound radiated by low‐frequency vibrations of slender bodies

摘要: Simple and practical formulas are derived for computing the near or far sound‐pressure field radiated by a slender body which vibrates in low‐frequency whipping mode, accordion mode water. The calculations can be made simple quadratures, require specification of modal vibration pattern along length, cross‐section area mean radiation impedance coefficient estimated from independent data calculated an explicit formula here. Comparison is with several other methods used to analyze these fields. analyses specific examples general technique transforming solution incompressive that valid near‐ farfield acoustic compressible medium.Subject Classification: 20.55; 40.20.
