I was waiting for some else to address this.  Unlike insects such as  
grasshoppers, bees don't have a tympanum (a form of ear).
 

Until recently, many thought bees did not possess 'hearing'.   That 
viewpoint has been modified.  We now know they perceive substrate  (comb) 
vibrations, and as such, probably have a form of hearing for at least,  low frequency 
sounds.  Also, one would imagine that queen piping has a  function. 
 
Do bees hear?  Probably.  Is it like mammalian hearing - probably  not.
 
General agreement seems to be, many of the sounds we as humans hear,  those 
that are transmitted through the air, are probably not perceived  to any 
extent by bees.  But, I'll bet they perceive the booming bass of a  teenager's 
car blaring rap, where you yourself can feel the bass thump.   Same may be 
true of when the lawn mower rattles by too close to the hive.
