explain how bats use ultrasound to catch a prey
Answers
A bat puts 600-700 kilometers of airtime every night. The animals fly low and catch insects at speeds of approximately 40 meters per second. The bat uses her hearing in the evening to navigate her way to prey. Bats continuously catch insects using an advanced navigation system called echolocation. The bat emits very high frequency ultrasonic waves. Its calls are pitched at 20-100 kilohertz, which frequency is too high for people to hear naturally. Their sounds are reflected in the environment, hit different objects and as echoes return to the bat. The echo signals allow the bat to create a mental map of its environment. Rain, wind and snow noise disrupts echo signals, making it more difficult for the bat to take a picture of its surroundings. The big night - time movements of the bat also produce sound that disturbs the echo signals. But despite poor weather conditions, bats manage to catch their target prey.
