Damage

Not sure if anyone else get this. With the radio off and at a stop, I can hear this odd noise coming from the rear of the car as if it's coming from the speakers. It's like a really low subtle rumble. Almost sounds like a motorcycle engine rumble from far behind the car. Is this part of the noise cancellation that's happening?

I guess no one else gets this noise? I've been trying to listen to this noise more and it sounds like some kind of pump pushing fluid around.
