Your compressor wheels aren't touching anything. That's the dentist drill noise, not the siren. If that were the case, you'd know you had a very serious problem. And as you said, the noise wouldn't go away. You have a very, very common noise. A lot of people don't even know the car isn't "supposed" to sound like that. Like I've told you about 5 times now, relax and go drive your car!
