Ignoring side reactions DD spits out about 1/4 of the energy and has a smaller cross section. There's also a 50/50 chance that reaction spits out tritium instead of helium 3.
It's much harder to do than DT hence the focus on DT, but not impossible.

Wonderful explanations here about Li7 breeding and what not. I would just like to add that D-T can be often seen as a stepping stone to a D-D reactor. D-T is easier, that's why its the immediate goal, but the next step on the path is D-D which doesn't have these problems.

Tempeture gradients can conduct sound along the ground. Importantly, snow being a good sound absorber tents to quiet everything down.
