Thank you for coming forward with this and I am going to do the best of my ability to sort all of this out and its hard for there are so many different opinions out there but constant buzzing sounds and noises are plentiful in the world but this particular one at this particular time I will check out..When my girlfriend calls to check on me after my car accident this morning I am going to ask her to do me a favorite--drive me to her house and let me have a cup of tea or something or even maybe go out to breakfast in a different area to see if I still hear this sound because it is very annoying, I would drive her but my vehicle needs some attention and I do not trust it because the whole side is dented--how terrible but it could have been so much worse and I am fine but anyway I will get out to go to breakfast and see if I can still hear the sounds---hate to think it is me---but it might be--so I am investigating this first...lol Thanks for the post..clancey
