On my last trip to Belgrade, I captured these 5 Pedestrian Underpass Sound Effects. The place gave the impression of a small parallel world, just below a busy street. Some people used the “tunnel” just to cross the street, others to do their shopping, as there were several little shops down there. In the footage you can hear people passing by, the distant traffic above and also the buzzing sound of escalators and a ventilation system. Check out the preview and the sound list for further info!
