If a tympanic membrane has basically no vibrating capacity (i.e. it
is perforated) how much hearing would be expected, if any?
and is bone conduction affected at all?  i would think not.

It all depends on the size of the perforation.  AC threshold would increase in
proportion to the size of the perforation, up to about 50 dB.
