I've already walked around on the main floor.  The modem/TV/landlord's laptop is in an alcove off the kitchen on the north side of the house. That whole area is very "hot" with frequencies. The kitchen also has a cordless phone which spikes the Acousticom meter.  Once you walk out of the kitchen into the living room you get away from all the louder kitchen frequencies and that's where you begin to hear the "clacka clack" sound continuing to the south end of the house.  My bedroom is above that, also on the south end.  I can hear the sound both on the main floor and on my bedroom on the second floor.
