For humans, OSHA safeguards to protect human  hearing usually kick in at no more than  8 hrs at 90 decibels of noise exposure.  Louder than that and the ear protection equipment needs to be used.  Sure  would hate to have to fit every bee with ear plugs - would  first have to find the 'ears' -  antenna caps and fuzzy feet covers?


This may not be the right forum,  but how do you rate the sound "level" on something you can't hear and does it still have an effect if its not really in your range??
  IE is a High frequency sound at 90 DB a problem if you don't hear it?  I have lots of problems with sound already so just curious.
