    which is basically just concrete

    This is why.

    A lot of European countries have thick concrete or brick walls, especially in older houses. American (and Australian, New Zealand, etc) houses are generally a wood frame with drywall for the walls (also referred to Gyprock, gypsum board, plasterboard, or other names). It’s relatively thin, doesn’t block a lot of sound, and you could punch a hole in the wall given enough effort. Interior brick walls, when we do have them, are generally pretty thin.
