I presume the transformer core used in the transformer is made up of E & I combination of laminates.

1. Get some tools and tighten all the screws that holds the core laminates together.  The buzzing sound signify the core laminates are loose and are vibrating.

2. it is also possible to coat or revarnish the transformer core with some clear lacquer varnish.
