Is there any evidence for this ultrasound being a communication medium of any kind (I'm thinking less IPv6 or US English, and more insect or bird calls)? Any hint that they listen to sounds as well as make them, or that there's any information content in it? Or it's more like heartbeats and engine/fan noise, just a byproduct of processes doing what they do? |
