They can hear sound frequencies from 90 – 250 metres away, ranging from 10 Hz to 800 Hz, and they hear low-pitched sounds (below 375 Hz) best. Underwater humans are unable to hear low frequency sounds but can detect higher frequencies, up to 100 kHz.

Frogs without ears hear with their mouth by CNRS This image shows a segmentation of a frog's head, showing the two inner ears (light grey), the brain in between, and the buccal cavity beneath. Our ability to perceive sound direction works through a process known as binaural hearing, which essentially means “hearing with two ears”. Now, a new study shows that sound waves cause vibrations in a snake’s skull that are then “heard” by the inner ear.
