PLEASE HELP!!!
Ever since I moved into my house, all of my equipment has been experiencing some kind of interference. This is usually a "farting" noise that comes through the speakers (home theater, computer, guitar amplifier, telephone, etc.). As far as I can tell, this noise only occurs to devices plugged into the house's electrical outlets and phone jacks. There is no pattern to this noise. I kept a log for a while, but it didn't tell me anything. The noise will last from anywhere between 5 seconds to several minutes. It occurs at all hours of the day/night, regardless of which day it is. It also does not correspond to any of my appliances (central heating, washer/dryer, dishwasher, refrigerator compressor, etc). I have all the same equipment I had at my old house, and I never had a problem. It does seem to happen more often when there is moisture in the air (during the summer it doesn't happen nearly as much as it did last winter). Now, since it is getting more foggy at night, the noise is becoming more frequent again.
Electricians have replaced the entire electrical panel for the house. They have put in a new ground post (8 feet deep) and hooked up to a different feed from the utility company. None of these solutions worked.
I have some video I took on my cell phone of this noise and posted it to youtube. Please take a look:
