The sound comes from S.T.A.L.K.E.R., the first person shooter series by GSC Game World that began with Shadow of Chernobyl in 2007 and is set in the Chernobyl Exclusion Zone. Inside the games, stalkers carry a PDA that manages maps, messages and objectives, and its short beep announces incoming information. Clips of the tone circulated among fans as a ringtone and notification sound, especially in Russian speaking communities, before crossing into meme edits where any new task gets treated like a dangerous mission in the Zone.

Short PDA notification beep from the S.T.A.L.K.E.R. games, heard when a new task arrives in your inventory. Used as a ringtone, alert and meme edit cue.
This is the brief electronic beep from the PDA device in the S.T.A.L.K.E.R. games, the sound that signals a new objective or update while exploring the Zone. Lasting under a second, it is a clean, high pitched double tone that cuts through gameplay without speech or music. Players instantly read it as important information arriving, which is why it works so well outside the game as a notification joke. Dropped into a video, it turns an ordinary message, task or discovery into a mock mission briefing with quiet tension.
