Hyperboloid Coincident Acoustic Model by Jack Kassewitz and Mark Weber
The bottlenose dolphin, Tursiops truncatus, has had its dual phonation device(s) described extensively in the literature: it offers both binaural receiving and biphonic (or bivocal) transmitting capabilities. The following model, Photograph 2, is based upon my recording and analyzing their sounds and a bit of a hunch what takes place when you have an outgoing multiple source signal that has coincident wave behavior increasing amplitude arithmetically. A research paper will be forthcoming regarding this new model for echolocation.
