electrical noise. a bunch of stuff makes it. lights, TV (makes a lot), comp, etc. there are filters you can buy which stop the noise, but you need a seperate one for each appliance. (thats what my dad did). i dont know all the details of exactly what it is and how the fitlers work, but my dad is a comp programmer and knows everything about electricity, i see him on wednesday so i can ask him about it if you want (thats a sacrifice, he goes on and on and on and on about stuff like that going into every little detail).
