Australian pedestrian crossings use audible signals to help people, including those with low vision, know when it is safe to cross. The fast, repeated beep heard in this clip is the familiar walk signal used at signalised intersections across the country, distinct from the slower warning tone used when the light is about to change. Online, the recording is shared as a realistic street sound effect for videos, games and animations set in Australia, where its instantly recognisable rhythm helps establish location without any visual explanation.
