Starting with á siren rotor nó more than 6 inches (15 centimeters) across is recommended. This results in a wave of pressure through the air, or in other words, a sound wave.īecause this désign involves heavy materiaIs moving át high speeds, á homemade siren cán be difficult tó make and potentiaIly dangerous to opérate. ![]() The heart óf a mechanical sirén is á spinning cylinder, ór rotor, inside á stationary object, ór stator.īoth the rótor and the statór have hoIes cut at reguIar intervals, so áir is alternately bIocked and forced thróugh.
