An acoustic signal with a single frequency and few starts and stops would be difficult for predators to localize because it lacks spatial information. A broad range of frequencies or a complex temporal structure would provide more information about the location of the alarm, while a pheromone or a visual signal rely on the predator being in close proximity to the prey.
