Simply Question: How do do Turtles produce sound

[Luckyday]

I know that Turtles feel vibrations rather then just hearing them but how do most of them produce it? This question also extends to sea turtles, because I keep trying to look up information on them and only thing that I found so far is that Leatherback turtles have larynxes. Do sea turtles and water turtles have larynxes?

Hmm, a while ago there was an article about a study about how this one type Amazon (I forget what they were!) turtle communicated with their eggs and other turtles by low frequency sound.
That's probably the worst summary ever! I'll go digging for it

That was also the only article that I was able to find. It really go into detail of how they can talk. Nothing about if they have vocal cords, and what not.
