Question

Infrasound can be heard by which of these animals?
A. Dog
B. Bat
C. Rhinoceros
D. Human beings

Answer 1

Hint: Infrasound, sometimes referred to as low-frequency sound, describes sound waves with a frequency below the lower limit of audibility (generally 20 Hz).

Complete step-by-step answer:
The study of such sound waves is sometimes referred to as infrasonic, covering sounds beneath 20 Hz down to 0.1 Hz. and rarely to 0.001 Hz. People use this frequency range for monitoring earthquakes and volcanoes, charting rock and petroleum formations below the earth

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.

The soundtrack to a wild rhinoceros's life is wind passing through the savannah grass, birds chirping, and distant animals moving across the plains. But a rhinoceros in a zoo listens to children screaming, cars passing, and the persistent hum of urban life.

So, option C is correct.

Note: Whenever we come up with this type of problem then we should also know that Other research has considered the influence of diet and physical surroundings, but scientists speaking at a conference said they believed the animals' soundscape might be crucial. Researchers in Texas are investigating whether the hum and rumble of urban life is one of the factors that hinders the captive breeding of rhinoceroses.
