Audible pedestrian signals are installed at many road junctions across Singapore to assist visually impaired people, using electronic tones that change pace to signal when to wait and when to cross. The sound became widely shared online as listeners recognised it from daily commutes, school runs and trips through the city centre. Clips are now posted as city ambience, ASMR and nostalgic reminders of Singapore, and creators reuse the recording whenever they need an unmistakable street crossing atmosphere without filming a junction themselves.
