This indicates that the field across the aperture is more truly Gaussian than for a conical horn.

For conical horns, the gain is:

The bore is generally cylindrical as opposed to the more conical horn; thus, the "feel" of the mellophone can be foreign to a horn player.

One technique to deal with this involved using a Stroh violin-which was fitted a conical horn connected to a diaphragm vibrated by the violin bridge.

Often now with the use of converters, traditional conical horn mouthpieces are used to achieve the more mellow sound of a horn to make the marching band sound more like a concert band.

Dual-mode conical horn - (The Potter horn ) This horn can be used to replace the corrugated horn for use at sub-mm wavelengths where the corrugated horn is lossy and difficult to fabricate.

Whereas the Waterloo Helmet has straight, conical horns with a broad base that are stylised representations of animal horns, the helmets depicted on the carvings at Orange show realistic, curved bull's horns between which is placed an upright wheel.

It was said that Benjamin was really the father of Roger Button, that he was his brother who had been in prison for forty years, that he was John Wilkes Booth in disguise--and, finally, that he had two small conical horns sprouting from his head.
