They whistle
Dolphins communicate because it's their way of talking to each other. For example, every dolphin has a signature whistle. They use these whistles when their in danger, calling to someone, or to tell each other apart.
Because a dolphin's ear frequency is higher than a normal human's, so they have to have higher pitched whistles so the dolphins can here them better. Plus, high sound frequencies can travel underwater easier so dolphins can hear them.
Dolphins talk to each other by using clicks and whistles. Some people use click languages. Some people use whistle languages. No group of people speak a language consisting of both clicks and whistles and no spoken words. Perhaps if someone created one it would become possible to talk to dolphins.
