My house is snuggling in a nice 5-inch north London
blanket of snow and outside, traffic noise has decreased
to the level it normally is at night.

They haven't plowed the streets?

Or is London like Atlanta, where deep snow is so rare that they don't even
have any plows to send out?

The atmospheric
pressure and the supplied heating must be doing something
to the sound transmission qualities of air.

The snow on the roofs acts as an acoustic isolator of sorts.

My hi-fi sounds wonderful....

Especially after due consideration of the effort required to go out and do
something else! ;-)
