Its six horns are each 3 feet (91 cm) long. The siren has an output of 138 dB(C) (30,000 watts), and can be heard as far as 25 miles (40 km) away. In 1952, the cost of a Chrysler Air Raid Siren was $5,500 [1] (equivalent to $65,076 as of May 2024). The United States government helped buy sirens for selected state and county law enforcement ...
A horn loudspeaker is a loudspeaker or loudspeaker element which uses an acoustic horn to increase the overall efficiency of the driving element(s). A common form (right) consists of a compression driver which produces sound waves with a small metal diaphragm vibrated by an electromagnet, attached to a horn, a flaring duct to conduct the sound waves to the open air.
An air horn is a pneumatic device designed to create an extremely loud noise for signaling purposes. It usually consists of a source which produces compressed air, which passes into a horn through a reed or diaphragm. The stream of air causes the reed or diaphragm to vibrate, creating sound waves, then the horn amplifies the sound making it louder.
In Norse mythology, Gjallarhorn (Old Norse: [ˈɡjɑlːɑrˌhorn]; "hollering horn" [1] or "the loud sounding horn" [2]) is a horn associated with the god Heimdallr and the wise being Mímir. The sound of Heimdallr 's horn will herald the beginning of Ragnarök , the sound of which will be heard in all corners of the world.
Paul Wilbur Klipsch (March 9, 1904 – May 5, 2002) was an American engineer and high fidelity audio pioneer, known for developing a high-efficiency folded horn loudspeaker.

The vuvuzela / v uː v uː ˈ z ɛ l ə / is a horn, with an inexpensive injection-moulded plastic shell about 65 centimetres (2 ft) long, which produces a loud monotone note, typically around B♭ 3 [2] (the first B♭ below middle C). [3] Some models are made in two parts to facilitate storage, and this design also allows pitch variation.
The diaphone horn was based directly on the organ stop of the same name invented by Robert Hope-Jones, creator of the Wurlitzer organ. [1] [2] Hope-Jones' design was based on a piston that was closed only at its bottom end and had slots, perpendicular to its axis, cut through its sides; the slotted piston moved within a similarly slotted cylinder.
