In general, dolphins make two kinds of sounds, “whistles” and “clicks” (listen to the false killer whales on this page). Clicks are used to sense their surroundings through echolocation, while they use whistles to communicate with other members of their species and very likely, with other species too.

What sounds do dolphins make for kids?
It turns out dolphins make all kinds of sounds: clicks, squeaks, whistles, and creaking noises. Bottlenose dolphins make as many as 2,000 squeaks per second; the sounds bounce off objects, telling the dolphins how far away they are.Jul 17, 2020
Where does the dolphin sound effect come from?
Sounds are produced in three pairs of air sacs located underneath the blowhole. After the dolphin takes a breath, it closes its blowhole, and air returns from the lungs into the channel leading to the blowhole, and, into one or more of the air sacs. The air inflates the sacs.
Who discovered echolocation in dolphins?
This information is critical for dolphins to find food and navigate in dark or murky waters. Echolocation was first studied in depth by famous marine explorer and scientist Jacques Cousteau over 60 years ago.
What travels in a sound wave that is coming from the mother dolphin?
The sound wave speeds through the water, bounces off the object under investigation, and is reflected back to the dolphin. Fat-filled cavities in the dolphin's lower jaw receive this information and auditory nerves conduct it to the middle ear and brain, where an acoustic picture is created.Jun 12, 2008
Why do dolphins sound?
The sounds that a dolphin makes underwater serve to help them navigate, locate food, glean information about the environment, and to communicate with other dolphins. These sounds are generated inside the dolphin's head, under the blowhole, and, generally, without air escaping from the dolphin's blowhole.
Can people hear dolphin sounds Why?
While echo location clicks can range up to about 150,000 Hz (about 8 times higher than the normal human hearing range), a lot of these clicks occur at frequencies as low as about 2,000 Hz. So people can easily hear them with the proper hydrophone (underwater microphone).
What sounds do dolphins make when happy?
In a new study published this month in The Journal of Experimental Biology, marine biologist and National Marine Mammal Foundation president Sam Ridgway and a team of scientists found that dolphins and beluga whales make “victory squeals,” or noises when they're happy.Aug 21, 2014
