Narrative:

Our anticipated landing runway was 22R. Approach control advised to change to runway 22L and vectored us to an angling downwind. Approach cleared us for the visual approach. Focus shifted to energy management to be stable on final. I do not believe that the controller advised us to switch to tower. If he did; the call was not received. We did not notice this omission. Very low traffic volume and the fact that lit had cleared us for runway 22L made it seem like one controller was working several positions. Upon transferring control of the aircraft to the captain on rollout; I noticed that tower frequency was not in the radio and thought that we had landed without proper clearance. No traffic conflicts occurred. The captain phoned the tower supervisor after shutdown to clarify the situation and he was unaware of any problem.
