I thought that the refrigerator was more about soundproofing (that way it wouldn't matter if it was listening or not.) I think it depends on the model. I tested a couple of phones, including a blackberry, inside my fridge a few years before Snowden did his thing. We put them in and then tried to call them and none of them rang. But the fridge was one of those trendy stainless steel models. Perhaps a more ordinary fridge would have less effect on signal strength.
