How can Snakes hear????

like many other animals, snakes have two ways of detecting sounds: earthborne and airborne. The earthborne vibrations are passed through the belly muscles to special receptors along the spine and thus transmitted to the brain. Airborne sounds are transmitted to the lung from the skin receptors to the eighth cranial nerve and inner ear. Most snakes can hear a person speaking in a normal tone of voice in a quiet room at a distance of about 10 feet (3 m).

Snakes cant hear they feel the vibration of people moving around them.
