It wouldn’t be any use for birds of prey, but they may hear large mammals and reptiles approaching. The Reptile Ear: Its Structure and Function. Peripheral hearing mechanisms in reptiles and birds (Vol. Snakes mostly have simple, tuatara-like papillae, which suggests that they have secondarily lost a more complex type of auditory organ.

And any way, snakes don't appear to respond to loud noises. Popper. Snakes detect pheromones using a specialized organ called the vomeronasal organ, also known as the Jacobson’s organ. This fools other males into trying to mate with them, distracting them from the true female. For example, a rattlesnake won’t respond to pheromones left by a garter snake.
