I wonder how much ambient noise affects Audyssey? It seems like everytime I run it the neighborhood dogs decide it's a good time to start barking in unison, or some dude wants to rev his car engine in his garage, or the neighborhood kids start yelling and skateboarding. I have the window shut and everything, but I can clearly hear it all.
It used to drive me up the wall because just as I would start the calibration process, the workers would come and cut the lawn in the back (I live in a condo). GRRR. I did turn off my AC/fridge before calibration though. The chirps are not that loud, so it's very doable at night time.
