This audio clip begins with the everyday hustle and bustle of a busy city. The distant hum of traffic sets the scene, with cars swooshing past in a constant stream. Amidst this backdrop of urban life, the distinctive sounds of a bus come into focus. The rumble of a large engine approaches, growing louder and then slowing as the bus pulls into a stop. There's a hissing noise as the bus's air brakes engage, followed by the mechanical whirring sound of automatic doors opening. The soundscape is then filled with the chatter of disembarking passengers, their footsteps, and the occasional clang of loose change. The doors then close with a hydraulic sigh, the engine revs, and the bus pulls away, leaving behind the familiar sounds of city traffic. This audio perfectly encapsulates the essence of public transportation in an urban setting.
