Does a pilot hear the sound barrier breaking from the cockpit of the aircraft they are operating?

I am guessing the front half of the aircraft, the portion forward of the engines breaks the sound barrier first, and at that point the plane is traveling faster than sound.  So will the pilot actually hear it?

No. 'Breaking the sound barrier' does not cause a discrete bang or audible noise.

The bang we hear is the plane flying by. The pilot is moving along 'in' the bang, so he doesn't have the opportunity to hear it. 

The only indication the pilot has is on the instrument panel, or possibly through some handling changes depending on the plane.
