How to isolate a refrigerator?

I did a search on the most quiet Fridge around and this name continually pops up every time. Might be the best upgrade you ever made...

Liebherr is the worldwide leader in premium refrigeration.

With over 50 years of experience in cooling, the German manufacturer sets the pace with continuous product innovation and a proactive approach to responsible manufacturing.

Liebherr brings fresh, European design to the North American marketplace, providing outstanding built-in, freestanding, and fully integrated refrigeration and an extensive selection of wine storage units.

it's true that you can spend megabucks on super-quiet (always European) fridges, but recent vintage, energy-efficient domestic ones can be quiet enough (+ cheap) to fix your problem.

I used to turn my fridge off for "critical" listening (it's in the same "great room"), but I kept forgetting to turn it back on.

@Miltcharlie: Thanks for the timer idea.

Actually my Hotpoint fridge is not too bad for noise. I think it was original equipment that came with the condo in '93 or so.

my <1year old fridge is LOTS quieter than the 20 year old GE it replaced...and has cut my electric bill by about 50kwh per month while being about 10% more capacity.

IF your current fridge is more than about 10 years old, and IF the sound deadening ideas don't cut it, you may consider a new box.

On my brothers boat, he sometimes will put a small (2kw) generator on the upper deck. Adding a 2thick of those large foam floor tiles made it work and cut genset noise drastically. Tiles available at any 'home despot' type store.
