Every Emergency Alert Explained + Sound

Every Emergency Alert Explained + Sound The scream your phone makes in an emergency is two notes from 1976, and every alert sounds the way it does for a reason: the two-tone Emergency Alert System and the zombie hack, CONELRAD's warning by silence, the Emergency Broadcast System and its 1971 false alarm, the weather radio that wakes itself up, wireless phone alerts and their rhythm, AMBER Alerts, Canada's two-chord tone and the Pickering mistake, Britain's first nationwide test, NL-Alert and Europe's phone warnings, Israel's Red Color voice, Ukraine's Air Alert app with Mark Hamill, the Hilo tsunami siren that people heard and ignored, Japan's earthquake chime built by the Godzilla composer's nephew, and the National Alert that no American phone can turn off, each with its real sound. 0:00 Two notes from 1976 0:29 1.
