Just look up "acoustic siren" or "siren for frequency measurement" and you'll get hits like http://americanhistory.si.edu/science/sirens.htm

This is so rad.

This second one is obviously quite out of tune - which is ironic for something based on a device that was historically used for precision frequency measurement. =)

Right. A search for "Helmholtz siren" turns up some stuff, including this
video of a historic piece "in action":

http://musicthing.blogspot.com/2007/05/jamming-with-150-year-old-helmholtz.html

And there are some neat drawings and descriptions in the Helmholtz book (On
the Sensations of Tone), too.

This (double siren) video is a fantastic implementation! Interesting that
the organ is based on a 1915 patent.
