The siren can sound six signals, just like most other sirens produced by Whelen; [ 8 ] however, it is not voice-capable like the company's WPS-2900 and ...
A horn loudspeaker is a loudspeaker or loudspeaker element which uses an acoustic horn to increase the overall efficiency of the driving element(s).

Diagram of a typical locomotive air horn power chamber, showing operation. Train horns are operated by compressed air, typically 125–140 psi (8.6–9.7 bar), and fed from a locomotive main air reservoir. When the engineer opens the horn valve, air flows through a supply line into the power chamber at the horn's base (diagram, right).
(right) Electric megaphones use a type of horn loudspeaker called a reflex or reentrant horn. The sound waves travel in a zigzag path through concentric widening ducts (b, c, and d) . An electric megaphone is a handheld public address system , an electronic device that amplifies the human voice like an acoustic megaphone, using electric power.
