Acoustic resonance is an important consideration for instrument builders, as most acoustic instruments use resonators, such as the strings and body of a violin, the length of tube in a flute, and the shape of, and tension on, a drum membrane.

Acoustic length or effective length is the quarter wavelength generated by the whistle.

In some cases, riot squads may also use Long Range Acoustic Devices, water cannons, armoured fighting vehicles, police dogs or mounted police on horses.
