Sure sounds like typical local noise from something in your home (or a near 
neighbors home).  Have you or someone else in the house recently acquired a 
new electronic gizmo, appliance, or ??    It could be most anything but the 
switching power supplies used for almost everything these days are common 
culprits.  The worst noise I have ever experienced came from a 12 volt wall 
wart used to power a halogen desk lamp.
