	Siren (noisemaker) - Wikipedia, the free encyclopedia
		Siren s are devices making sound to alarm others, such as the air raid siren or the sirens on emergency service vehicles such as ambulances, police cars and fire engines.
		The pneumatic siren, which is a free aerophone, consists of a rotating disk with holes in it (called a rotor), such that the material between the holes interrupt a flow air from fixed holes on the outside of the unit (called a stator).
		Sirens are also used as musical instruments, such as in Edgard Varese 's Hyperprism (1924), Ionisation (1931), and, recorded, in his Poeme Electronique (1958).

		I'm trying to write a program to produce various types of siren sounds, so as to immitate police sirens, abulance sirens, air-raid sirens, etc..
		Unfortunately, the result sounds more like someone playing with the pitch-bend wheel on an analog synth than any siren one might actually hear in the real world.
		An alternative to multiple sines or sampling the whole siren would be to record a siren, then take a small looped sample while it is steady at its highest frequency.

	Patent 4198706: Generation of low frequency sound under water
		Mechanical low frequency noisemakers have had considerable use and are efficient within their limitations; however, they become excessively large and expensive if they are made capable of producing the intensities and frequencies required for the satisfactory sweeping of low frequency acoustic mines.
		Both these types of noisemakers have air within their moving parts and hence are quite vulnerable to the explosion of nearby mines so that if they are just marginally successful they become expendable.
		1 a noisemaker 10 is shown supported at a suitable depth, say 25 to 30 feet, in a body of water 11 by a float 12 through cables 13 secured to the float 12 and to lifting pods 14 provided on the noisemaker 10.

		Sure, bass-rattling boom cars and Harley hogs that send sound to our brains at levels exceeding 100 decibels are cries for attention--the audio corollary to the glut of tell-all talk shows and "reality" programs in which people set new standards for self-abasement in exchange for a precious few minutes on the air.
		But these aural assaults are about more than just getting the noisemaker noticed; they're a kind of drive-by bullying--a way of brutalizing our soundscape, of anonymously flipping off the powers that be.
		The more we have to play by the noisemakers' rules, the more we lose sight, or sound, of the value of quiet.
