Hi,
   Does somebody know how to calculate the air damping force of a hole-plate?
The length and width of the plate is from 5:1 to 2:1, and the height of the
holes is much larger than its radius.
   BTW, does somebody have the E-version of the paper"On the acoustical
resistance due to viscous losses in the air gap of electrostatic transducers" by
Z.Skvor published on "Acustica" 1967 ?
