All advice and experience most welcome here.

If you want to improve sound insulation, easy way is to fit small
dimenstion joists 2-3" below existing ceiling and fit new ceiling to
that, so that floor and ceil are decoupled.

Otherwise just patch the hole with PB and fill, I'm not sure why one
would need to do anything else.
