Foghorn on Ailsa Craig, where the fog signal was discontinued in 1966. Since automation of lighthouses became common in the 1960s and 1970s, most older foghorn installations have been removed to avoid the need to run their complex machinery, and have been replaced with electrically powered diaphragm or compressed air horns. Activation is ...

NASA scientists believe the ominous noises could potentially be the "background noise" of the Earth otherwise known as "Ambient Earth Noise." Since this still lacks scientific confirmation ...
This arrangement opens and closes the circuit hundreds of times per second, which creates a loud noise like a buzzer or electric bell, which sound enters a horn to be amplified. A traditional style automobile horn includes an expansion chamber cast into its body, once spiral shaped, to better match the acoustical impedance of the diaphragm with ...
