There are 3 sources of noise in converters
1: Most all of them have a fan, IF the trailer has been sitting for "Some time" (months) the batteries have self discharged (not to mention parasitic loads that never get shut off) and they are very hungry, in fact they are likely damaged, The converter will work hard to bring 'em back up and thus it will need to fan itself.. NOTE in some installs just sunlight is enough to fire up the fan.
2: Some older converters have big, heavy, iron core, power transformers.. These cores are made up of many many leaves of thing pressed iron, varnished together, well over time the varnish dries and flakes away and when you plug in the leaves vibrate,, and thus hummmmmmmmmm
3: This one is more likely a "HISS" than a HUMM.. it's TROUBLE.
