Infiniti Service Bulletin regarding Drive Belt issue/failure

Can anyone describe what the drive belt noise sounds like? I am getting an odd noise between 2.5k and 3k under medium load. It doesn't sounds like a squeaky or chirp but more like (and I know this sounds crazy) a semi truck horn from far away lol. Its very faint and very brief but easily repeatable.
