I have a door that when closed normally slams against the frame
and due to the plasterboard partitions the frame is set into the
slam reverberates around the whole flat. Other than coating the
frame with bubblewrap any ideas?

Stick a bit of draught-proofing strip along the top, so that it has to
be pushed slightly to catch?

(Might be worth a try.)
