Make your own air-raid siren and make a heck of a noise!
posted January 20 2015 21:15.10 by Giorgos Lazaridis




The principle of operation is that air is forced through slits that open and close with specific speed, producing a fixed frequency. An air-raid siren produces two different frequencies - This gives its distinct sound.

Matthias Wandel compiled this video with detailed steps on how to make your own wooden air-raid siren model powered by an electric motor. Enjoy watching.
