Place this clip right on the cut where a phone graphic or chat bubble enters the frame, before the actor reacts. Follow it with a Bell Ding Sound Effect for a second device in the scene, or swap it out entirely on the next cut to keep viewers guessing.
About this sound
This clip is a brief Samsung whistle alert, a high-pitched synthetic tone lasting under two seconds with a clear, piercing whistle character. It feels instantly distracting and playfully annoying, triggering that urge to check a pocket or screen. It comes from Samsung Galaxy phones, where it served as a familiar notification tone.
