Low, constant hum that woke me up. It kept me from sleeping for almost an hour. It sounded like something out of a movie, and it could be heard all over my house and down the street. It was an idle that I expected to go away, but it didn't, and it drove me insane. It was very very low, almost like a bass clef note.
