As we know, bees are deaf, but are very aware of vibrations, so I can see the sense in this.My understanding regarding the dances of bees which are carried out on the comb face are;
during the waggle dance movements a train of pulsed sounds is made at the low frequency of, not sure on this bit, 250-300 Hertz, with a pulse duration of 20 milliseconds. These sounds are produced by the wings of the dancing bee.
Follower bees place their antenna very close to the dancers abdomen, where the movements are intense.
That's all I can remember about how communication of the dances inform others the distance and direction.
