1: Biosonar Signals		2 of 2

The shape and structure of the signal controls how it carries information back to the animal. That means the design of the sonar signal is vital.

All this considered, we can tell a lot about an animal's sonar system by listening to the signals it transmits. This is often the first port of call for scientists trying to investigate the sonar of an animal: what is its sonar signal like? Is it like man-made sonar signals? How would it perform as a sonar signal? Would it allow the animal to "see with sound"? Next, you can listen to the different kinds of sounds that animals use as sonar signals.
