This is a roughly ten-second Japanese emergency alert alarm, the sharp, repeating warning tone used by Japan's J-Alert system. Its insistent pattern creates a tense, urgent feeling, like a real broadcast interruption demanding immediate attention. It works best when that sense of official alarm is exactly the reaction you want.
