What can be expected noisewise in strata living

I am living in a relatively new building and we are currently going through the defects process.  What would be considered as normal noise in such a building?  People are complaining of noise, such as: music coming up through the double brick walls into their apartment; noise through closed apartment doors from people talking in the lobby outside; transference of noise at an increased volume when furniture is moved on the tiled terrace area of the apartment above but impacting, not directly underneath as one would expect, but diagonally across into the lounge room of the apartment below; and other noises such as hammering, slamming of sliding doors, children running and playing on the terrace area.

Some of these would be expected I would think, but others may be because of incomplete or shoddy workmanship.

Can anyone enlighten me?
