Best Answer: Turtles do not HEAR- other than sensing vibration, so it only makes sense that they do not do much in the way of vocalizations. It does not help that they don't have vocal cords! However, they do make noises. During aggression, courtship, mating, egg-laying and similar situations, most turtles and tortoises make some sort of noise. The noises are basically a noisy breathing. They range from hisses and almost moaning, to a pig-like grunting, and even an almost chicken like 'cluck'.
