Ice cream trucks have used looping chime melodies since the mid twentieth century to announce their arrival from blocks away, turning a simple tune into a neighbourhood signal for summer. Online, that familiar sound was clipped into a short sound effect and shared on soundboards and in video edits. Creators reuse it as instant shorthand for childhood, heatwave days and sweet treats, because audiences recognise the meaning in a second even without seeing a truck, a cone or a street on screen.
