If the turtle making the noise is the one that nearly drowned, water no doubt got into his lungs, and it is possible that they aren't fully cleared. I'd keep a careful eye on him just in case something develops. Better yet, consider that vet visit.
If, as you said, he does it in the water, is he close to the glass when he makes the sound? Sometimes breathing close to the glass will result in a sound (like when you blow into the neck of a bottle). But given his history, the vet would be your best option, I think.
