Snakes can 'hear' because vibrations on the ground cause their jawbones to vibrate, which in turn vibrates their inner ear and sends a signal to the brain. One of my followers watched the video and subsequently sent me a fantastic recording of how our voices might sound to snakes based on their possible hearing range. Regardless of whether a species of animal is social or solitary, they all need to communicate with others from time to time.
