Ad Hoc: Establishing a horn project.

The Horn Project Entry form

Screen showing all the data entry for the 'Big-Fun' horn. Chamber volume is automatically calculated and displayed.

Hitting the 'calc' button will save the record, and recalculate the expansion, in case you made any changes to the horn's physical characteristics.

Note that the M is valid for hyperbolic horns only, and that the T/S parameters are valid for front-loaded horns only.

Any project entered in this form may be retrieved later on for update/simulation.

The expansion list at the bottom shows you:

• Area at distance X from throat
• Square dimensions derived from that area
• Duct height for a constant-width horn
• Angle (V) between "duct floor" and "duct roof" for a constant-width horn
• The length of the curve over the last Delta(X)

for the whole horn expansion.
