CORE 2 SO FIRST TIMERS: DD-3 (A-D)

The loudest bats use sonar as loud as the Space Shuttle.

To protect themselves from going deaf by their own sounds, bats separate the bones of their inner ear as they make each sonar blast.

The stirrup bone (which looks like a horse’s stirrup) is connected to the cochlea.

Bats can send out two different types of frequencies. Scientists call one “FM” and the other “ZF”.
