I recently moved house and inherited a kitchen with an integrated freezer. The freezer compressor noise was hardly noticeable during the day, but at night could be heard as an annoying hum in the bedroom above the kitchen.
The noise was being conducted via the freezer cabinet, its attachments to the kitchen unit and worktop, and then the kitchen wall to the bedroom wall/floor.
I solved the problem by removing screws from the attachment points, moving the freezer a millimetre or so away from the kitchen unit side panel, enlarging the central hole in the attachment strip for the worktop, inserting a rubber grommet in the hole and using a single screw to attach the freezer via the grommet to the worktop. So the freezer is now more or less a free-standing unit.
The resilient single attachment point has proved adequate to prevent freezer displacement when its door is opened/closed. The hum is now inaudible in the bedroom.
