 In the same episode, he is able to "hear" the Ood's telepathic song where the humans could not.In "The Lodger", the Eleventh Doctor (pressed for time and needing to convey a great deal of information to someone) smashed his forehead into another person's forehead, causing a massive instantaneous transfer of information.He then commented that was just the general background, then repeats the action to transfer further information pertinent to the episode.
