## 9.10. Infinite conical horn

### Theoretical considerations

The equation describing the cross-sectional area S(x) as a function of the distance x along the axis is
$MathML$
(9.32)
where S T is the area of the throat, which is located at a distance x   =   x T ahead of the apex at x   =   0. In the steady state, the Helmholtz equation for the conical horn is obtained by inserting S(x) from Eq. (9.32) into Eq. (2.27) to yield
$MathML$
(9.33)
where
$MathML$
(9.34)
and
