How does penguins hearing compare to humans?

Answer 1

Although penguins hearing hasn't be researched much it is thought to be normal for most birds, but not as well as most marine animals.

Answer 2

Penguins have better underwater hearing than humans, as they rely on sound to communicate and find prey in the ocean. They are able to hear a wider range of frequencies and are more sensitive to sound vibrations underwater. However, on land, penguins' hearing abilities are similar to those of humans.
