The soundproof tunnel is used when the existing Sound Barrier wall cannot lower the noise due to the road expansion or Manhattanization of surroundings.

The soundproof tunnel at Pyongchon area in Beltway around Seoul has a round frames at ceiling. The ceiling is open around 10% and assembled transparent soundproof walls at the wall, which has glare effects.
