My bedroom happens to be on the other side of the kitchen, where the

with some extra space on the top.. The refrigerator is new, but at
night the noise can still be heard in the bedroom.

I am thinking about putting some kind of foam material to the wall in
the kitchen where the refrigerator is located. There's enough
clearance for a few inches of padding for sure.

Does anyone know where I can buy such things? I know I can get some
kind of adhesive sound reducing foam padding for computer cases, but
they are generally pretty expensive..

You don't want foam for this application, you want
recycled cellulose panels, (Homasote, or something
similar.) Well, what you really want is lead-filled
vinyl, but if you're balking at the price of foam,
you won't pay for that.

And whatever you're doing in the evenings that's
keeping you from sleeping, cut it out, or do it
in the morning. If I can sleep next to an oil-fired
forced air furnace, you should be able that manage
being on the other side of a wall from a refridgerator.

Less coffee, more exercise.
