This sound is based on a recognizable Samsung smartphone notification tone, then edited into an earrape meme version with extreme volume and distortion. Variants of loud phone alerts have circulated for years in meme edits, prank compilations and short-form videos because the sound is instantly understood before the distortion even peaks. It stays popular because it works as both a fake real-life interruption and an exaggerated reaction cue, similar to how a buzzer sound is used to smash a joke with sudden audio.
