The 212 are better noise-isolated. All engines witch vibrates or make any noise are build in special location. This room is noise-isolated build and has special basics to the hull.
In facts they can detect a coastal cargoship at range about 80 nautical miles and another 212 sub cruising in normal modus only in range under 100m. Therefore HDW had a slogan: "Nobody finds our subs well."

Amazing! 80 NM.
