Thanks Thomas,
That could be very interesting as well. Can you recall how the sounds you were 
were structured (whistles,pulses, sporadic  static)? 

The usual situation that leads people to feel bats are getting too close for 
comfort is  in 
calm air with a cloud of mosquitoes near your head. The insects trigger close 
bat passes, 
but there wouldn't be any correlation with sound.
