Hi Whitecap, the first thing I think I would do in your situation is to simply sit tight and wait...at least a month to 6 weeks or so. Home electrical systems can be thought of as a ’single large circuit’ that, with your own typical use patterns, has reached (more or less) a state of homeostasis. Anytime you make a change to the circuit (in this case the wiring) you run a risk of disturbing that homeostasis until enough time goes by for it to recover. If 6 weeks go by and there is Z-e-r-o change, then I’d be looking for a problem with the electrical system and not with my gear that I know happened to be doing quite alright before the alteration. In the case of a continuance of the sound problem, I believe I’d start with asking the electrician if he is qualified to be able to give you a reliable verdict on the state of your home’s ground (assuming it was originally designed with a ground...your original duplexes would all show 3-prongs, not 2). If he’s not confident he can be very accurate about the test results, perhaps he may know of someone who is (the true, correct method for checking ground properly can be tricky for the novice). Also, the effectiveness of the grounding for homes in many parts of the country tends to be at or close to nil after about a decade or so. Your electrician should know all or most of how to restore good grounding, the only tricky part may be accurately measuring it. While you’re at it, ask if your electrician if he actually disturbed any part of your home’s ground system in the course of his work...I know sometimes old connections that were broken can have much higher resistance when rejoined if not cleaned properly.
p.s. sorry to hear about your sister-in-law...my advice is to just get some old earbuds to your phone and just make hand gestures like you can’t hear her... :>)
