Question:

Which of the following species can hear the infrasonic sound?

Options:

dog

bat

rhinoceros

human beings

Correct Answer:

rhinoceros

Explanation:

Rhinos have extremely good ears, picking up infra-sound far deeper than the range of human hearing.
Rhinos, can hear down to a frequency of four hertz, whereas even a human baby, with entirely undamaged ears, can normally only pick up sounds as low as 20 hertz. Giraffes and elephants can also hear in this infra-sound range.
