Ambient noise only becomes an issue above a certain level, although some noise is more invasive than other.
If you have an ambient noise problem arising either from your home or from outside, first big steer is to listen at night when noise is way down.
Second, choose the location of your room if you can. Mine is in the basement of a stone built house. With the system down my room is very very quiet.
If you have a/c, switch it off while listening, as in many theatres and concert halls.
Remember also that room treatments absorb sound coming from outside the same as sound coming from inside.
