Signal whistle

A signal whistle was a mouth-operated device that made a high pitched noise in order to indicate a signal.
==Description==
These whistles could be made out of many common materials, but some could be made of ivory. They were used by humans and other races, such as hobgoblins.
Signal whistles were used in some places throughout Toril, particularly in Faerûn, Kara-Tur, Zakhara, and Maztica.
