##The scientists verified that a 30Khz signal was present at the transducer by mechanically coupling their teeth/jaw to the transducer - they just used a rod of wood (or metal? I forget). They placed the rod on the transducer, then bent down and put their tooth on the end of the rod. When the skull vibrated it was perceived as sound. Interesting isn't it?##They probably use the coefficient of friction to verify signal presence.
