About 20 minutes for me. But I spend a good 30 minutes with my dog--feeding him, letting him out, and a short walk.
It actually only takes about twenty minutes to get myself ready, but the mornings are far more involved than that. Up at 5AM, make the bed and dress, get my daughter up, fix breakfast, do my hair and makeup; then we walk the dog until my daughter's bus picks her up around 6:25AM.
Depends on the severity of both. I do not like stuff loud like (non-orchestral) concerts, yet I do not like it to be extra quiet.
I don't like it too quiet, I prefer a little background noise.
