The sound begins with the distinct, rhythmic clatter of a vintage hospital stretcher being pushed across a hard surface. It's a clear and identifiable sound, familiar from old hospital dramas, a metal cart on wheels transporting patients from one point to another. The echo and the resonance of wheels against the floor suggest a large, open space, possibly a long hospital corridor. The acoustic perspective shifts subtly, hinting that the stretcher is moving. It starts close, the sound loud and clear, almost as if you're standing right next to it, able to see the optical illusion of the wheels spinning fast. You can hear every detail, every squeak of the wheel, every rattle of the metal frame. As the sound continues, the stretcher moves further away. The noise grows fainter, softer, the details merging into a uniform hum. The echo grows stronger, bouncing off unseen walls, giving you the sense of distance and emptiness. The sound paints a vivid picture
