A applet computes resonance frequencies of a room,
which are of different modes (axial, tangential
and oblique).
The result can
be visualized via graphs or a data analysis table .

The algorithm is based on the following formula:

f = v / 2 * (p^{2}/L^{2} + q^{2}/W^{2}
+ r^{2}/H^{2})^{1/2}

v is speed of sound (344m/s).
L, W, H are length, width and height of a room.
p, q, r are integers (0, 1, 2...).
When two of the parameters (p, q, r) are zeros,
the frequency is axial; when one is zero, the frequency
is tangential; when none of them is zero, the frequency
is oblique.
