   The nomenclature is a bit of a problem:   
      
   The expression "Microphone with a figure-of-eight response similar to a   
   bidirectional ribbon" is a bit of a mouthful, and "Fig-8" in the text of   
   an article could be taken as a reference to Figure-8 in the   
   illustrations.  "Bipolar" has medical implications and "Dipole" has   
   already been taken by aerial engineers.   
      
   The BBC used "Velocity response", which is confusing if you don't   
   understand the maths behind the response - and it doesn't really help   
   you to visualise how the microphone is going to behave.   
      
   "Bidirectional" seems to be the best compromise, although it could   
   include hypercardioid, which has a smaller back response and a conical   
   null.   
      
   Perhaps we should settle for "Equi-bidirectional" - but I can't see it   
   catching on.
