sound observation 1

in my kitchen- The fridge is making a low, soft rumble that is constant. a couple ice cubes fall in the freezer and it sounds like high-pitched, tinny thuds that echo briefly.  I can hear my roommate's TV playing in the next room and it sounds like an old-fashioned radio announcer with a brassy voice, with a big band playing in the background. She and her boyfriend are talking, and her voice is soft and high, his is deep and carries, echos loudly. all of this is muffled through the wall. There is a different low rumbling from the air conditioner that cuts on and off every few minutes. Occasionally I can hear the soft whooshing/whirring noise of cars passing outside.
