They have ear 'holes' as do all lizards (excluding Cophosaurs). They have auditory bullae, like all lizards (including Cophosaurs), and encased in those are structures that pick up sounds, similar to ours. They hear whatever is around them and making noise.
Iguanas can hear but their hearing is terrible
Iguanas have a many predators that prey on them. Baby iguanas are prey for jungle cats, birds, turtles and even large fish. Large iguanas are pray for boa constrictors, caimans, hawks and eagles. many igs are captured in the wild when they hear the sound of a hawk (people trying to capture igs record the sound and play it when they see an iguana). when they hear that sound they freeze in their tracks which makes it easy for people to catch them.
Iguanas do not have movable ears like some other animals; instead, they possess external ear openings covered by a flap of skin. These openings allow them to hear sounds, but the ear structure itself is fixed. While their ears don't move, iguanas are highly sensitive to vibrations and sounds in their environment.
