Rats use ultrasound primarily for communication and navigation. They emit ultrasonic vocalizations, which are sounds above the range of human hearing, to communicate with each other, especially during social interactions or mating. Additionally, rats utilize ultrasonic frequencies for echolocation, helping them navigate their environment and detect obstacles in low-light conditions. This ability enhances their survival by allowing them to locate food and avoid predators.
