If they are projecting sonar images at each other, this would be much easier for us to determine than if they are using serial, syntactical language, right?
They may not be projecting shapes of actual objects, but if they are projecting shapes at all, it would probably be easy to record and reconstruct them visually for us to see, no?
I'm thinking if they so use 3-D sonar communication, they probably have a vocabulary of geometric symbols.
For instance, with our vocal apparatus, we can imitate sounds like "bark bark" or "buzz", but instead we say "dog" and "bee". This allows us to talk about things that don't make sound, including abstract ideas.
Perhaps they have 3-D geometric symbols, analogous to our words. Instead of imitating the sonar reflection of a school of fish, they might just have a shape that means "school of fish".
