Yep the noise was always an issue, and from what I've heard it's actually getting worse because construction quality is going down. (In the old days, Korea didn't have much experience in construction, so they compensated by pouring a generous amount of concrete and steel, or so I've heard. Now they know exactly how much they need, so walls are getting thinner and thinner.) A sad state of affairs.
