Air Horn Sound

Air horn alarm sirens can create enormous sound pressure and spread it across big distances thanks to the horns mounted on the top of the siren. The construction of pneumatic alarm sirens is different from mechanical sirens. While the mechanical siren creates the airstream with the help of centrifugal forces, the pneumatic alarm siren uses a compressed air canister to pump the airstream into the siren head.

Air Horn Sound

The air-powered alarm siren (air horn siren) is easily identified by the horns mounted to the siren's head. Similar to a mechanical siren, the air horn alarm sirens create their signal by interrupting the air-stream cycle with the help of a perforated disc. The spinning disc inside the air horn siren's head is called a rotor; it is electrically powered. The air horn stream is directed through the holes in the rotor and external vents. The spinning motion of the rotor either opens or closes the holes, which creates the air horn sound of the siren that is then directed to several air horns. The air-stream that is needed for the operation of the air horn is created by an compressed air canister underneath the air horn siren.

Benefits of Air Horn Sirens compared to Mechanical Sirens

The main benefit of the air horn siren is the extremely high sound level it creates. Air horn sirens can reach a sound pressure level of 130db (!) at a distance of 20 meters. The other benefit of the air horn is the use of pressurised air. With the help of compressed air from a tank, the air horn sirens can create a very high sound level almost immediately, which is very important for the proper operation of a siren. Air horn sirens also need less electrical power than mechanical sirens (but they do require more maintenance).

Many of these high-performance air horn sirens were de-installed after the Cold War because they were no longer used. You can still see the pylons that those big old sirens used to be attached to (although nowadays they are more likely to house a mobile antenna than a siren).

Two-tone Air Horn Siren

Unlike mechanical sirens, air horn alarm sirens can create a two-tone sound. Pneumatic sirens with air horns are typically used on ships. The bigger the ship, the lower the sound of the air horn. The Sounddogs Archive features some very nice recordings of ship air horn sounds and pneumatic sirens.
