well, there's one other sound. those bug killer plug-in's. if you have fairly acute hearing- you can go crazy from the high pitched (supposedly out of human range of hearing). i think it could be a form of mental torture. surprisingly they have them on new cell phones so that students (teenagers with more acute hearing) can hear their cell phones go off.
agreed about the vomit being a tie. although, i still think beginning violin players take the cake.
