According to the following site, dolphins use a series of clicks and whistles as a means of communication. A tissue complex in the nasal region is probably the most likely site of all sound production and sounds are probably produced by movements of air in the trachea and nasal sacs.
During some vocalizations, bottlenose dolphins release air from the blowhole, but scientists believe that these bubble trails and clouds are a visual display and not necessary for producing sound.

they also click for echolocation. The noise they make with their click bounces off objects and then they can "see"... just like bats

For sonar and "pack" communication is why. How, I'd reckon it's with their nasal cavities, or their vocal chords, same as homo sapiens.
