Acoustic Radiation Impedance of Caps and Rings on Oblate Spheroidal Baffles.
Abstract
The acoustic radiation impedance seen by curved vibrating caps and rings located on hard baffles of oblate spheroidal shape has been analyzed using eigenfunction expansion in oblate spheroidal wave functions. With the help of extensive computer programs the formulas have been numerically evaluated. The results are presented in families of plotted curves showing the effect of curvature on the acoustic radiation impedance. Calculations were made for ranges in acoustic size of 0.1 less than or equal to 20. (Author)
