The echoes that are reflected off the object are then received by the lower jaws. A special fat in the melon called lipid helps to focus the clicks into a beam. The clicks are emitted from the melon of the dolphin in a narrow beam. The process of echolocation begins when dolphins emit very short sonar pulses called clicks, which are typically less than 50-70 millionth of a second long. With sound traveling better in water than electromagnetic, thermal, chemical, or light signals, it was advantageous for dolphins to evolve echolocation, a capability in which acoustic energy is used, in a sense, to see underwater. It is a process in which an organism probes its environment by emitting sounds and listening to echoes as the sounds bounce off objects in the environment. What is echolocation? With God’s help, toothed whales developed echolocation, a sensory faculty that enabled them to survive in often murky and dark aquatic environments. So really we have come to the core of our journey dolphin sounds are primarily due to echolocation. This is mind blowing because as of right now there are only a handful of creatures on the planet with the capacity and intellect to form a complete language with their own species, and this proves and certifies without a doubt the dolphins limitless potential, intellect and ability. There are so many different sounds that can be emitted by the dolphin at so many different frequencies that scientists are certain that there has to be quite literally, a dolphin language, common sounds and signals that are repeatedly heard to form a coherent dialect of clicks and whistles so that other dolphins can understand.
The many uses of sounds by dolphins is still fascinating marine biologists to this day, but here is where it gets really interesting. The extent of which these sound waves can be utilized by the dolphins is simply mind blowing, and for so many different uses, from searching for prey underneath the sea floor, to scanning its surroundings for danger, to sensing potential predators, to even stunning and inflicting instant paralysis to smaller fish as to make their capture easier. They have been known to instruct each other as well as receive instructions and act accordingly.
Dolphin Speech is so complex that the sounds even cross the species barriers and enable different kinds of dolphins to communicate. Yet the dolphin’s sonar is much more advanced than human technology and can pin point exact information about it’s surroundings ranging from size, distance and even the nature of the object. In fact, the frequency levels range 10 times beyond what humans can hear! This system is called “Echolocation”, or “Sonar”, just like what a submarine uses to navigate while underwater. Utilizing their blowholes, air sacks and valves, dolphins can emit a very wide variety of sounds. Even a new baby dolphin, (calf), can detect it’s mother’s whistle within the pod soon after birth. A sound that other dolphins recognize as a particular individual. Scientists have discovered through observation and meticulous testing that each and every dolphin has a different sound just like you and me. So the questions are pretty straight forward, what are the kinds of sounds dolphins make and what do they mean if anything at all? To answer this we must take a look at research and evidence dealing with experimentation and trials involving sound and dolphins.
