cars making a roar/buzz type sound the more gas i give the faster it buzzes on 2002 Jaguar X-Type

it doesnt chirp, or overheat it just started yesterday. what does that sound like. wish i could explain the sound better. It sounds sort of like when u were a kid and you would clothes pin a playing card to your bicyle wheel. the faster you go the sound changes. Is there anything that could be rubbing something under there. I know this isnt much to go on. I need some direction. thanks.
