The sound is your compressor for your air ride suspension. It's more common on luxury cars but not uncommon on Subaru Legacy's. The sound is normal when you shut the car off but if it's running for hours, you have an air leak.

I had that system on my buick , every time you stated it the compressor would come on, I didn't know what it was , eventually the new rear shocks completely seized up and I went with a coil over conversion set , $300** bucks thrown into the scrap heap , isn't that nice ?
