Ice cream vans have used bells and simple chimes for decades to announce their arrival, long before recorded jingles became common, and the sound quickly became a cultural shorthand for summer, childhood and street food. Online, short clips of the bells are shared as sound effects for memes, edits and reaction videos, where the familiar tune instantly sets a scene without explanation. Its staying power comes from that instant recognition, since almost anyone who grew up hearing a van approach knows exactly what it promises.
