I can definatley hear them. I can track them from the bloody racket they make! Years ago on a caving trip in Yorkshire we were staying in a bunk house and decided to walk the mile or so to the pub. On the way i could hear loads of bats, but i was the baby of the group so no-one else could (all the rest were older men and women).
Once we got near the village and some street lights i could point to where an individual bat was (which they all laughed at) until the bat in question flew through the patch of light from the street lamp! They all shut up then.
