Geometrical Exponential Horn Calculations

[Hoerninger]

The attachment gives you a compilation of eighteen equations. Some of them are rarely to find if ever.

The results may be useful, for example calculating
a) cut off frequency of a given horn (or throat adapter),
b) volume by length and areas,
c) opening angle at mouth and
d) flare rate of horns with elliptical cross sectional area.
