Which animal has the best hearing?

The animal with the best hearing is actually the bat. Bats have evolved highly sensitive ears that allow them to detect very faint sounds and even echolocate. They can hear sounds at frequencies that are much higher than humans can detect. So bats are the champions of hearing in the animal kingdoms.

The average bat can hear sounds up to 100 kHz, which is about four times higher than the upper limit of human hearing. Bats can even hear frequencies above 200 kHz, which is the equivalent of dog whistles.

Bats use their sensitive hearing to navigate and hunt for food in the dark. They produce high-pitched sounds and listen for the echoes to create a "sonar" map of their surroundings. This ability is called echolocation and allows bats to hunt, avoid obstacles, and even communicate with each other.
