Experience the difference between expressway and motorway noise at 30 and 100 meters.

Experience the difference between expressway and motorway noise at 30 and 100 meters:

  • Expressway noise: Two-lane road with 15,000 vehicles/day at 80 km/h.
  • Motorway noise: Four-lane motorway with 59,000 vehicles/day at 110 km/h.

These examples illustrate how traffic flow and speed affect noise perception at varying distances.

Note: Listen to the sound files continuously to capture the differences in traffic dynamics. Avoid frequent jumping between files.
