Answer: Infrasound is a type of sound that has a very low frequency below 20 Hz. Humans cannot hear these sounds because our ears can not detect sound between 20 Hz and 20,000 Hz. But some animals, like rhinoceroses, can hear these low-frequency sounds. That is why they are called Infrasonic animals. Thus, the correct answer to infrasound can be heard by is option C. Rhinoceroses.
Complete Answer:
Rhinoceroses have very sharp hearing. They can both make and hear infrasonic sounds. This helps them talk to each other using sounds we can not hear.
Humans can only hear sounds from 20 Hz to 20,000 Hz. Dogs can hear sounds starting from 64 Hz, and bats hear at higher frequencies, about 9,000 Hz to 200,000 Hz. So none of these animals can hear infrasound; only animals like rhinoceroses can hear it.
So the correct answer is option c). Rhinoceros
Extra Facts: Many natural events create infrasonic sound, like volcanoes, earthquakes, thunder, ocean waves, and even jet engines.
Some animals use it to communicate or navigate. For example, whales and dolphins use it to find their way in the ocean. Elephants use infrasound to talk to each other and even attract males. Some animals can feel these sound waves, which may help them sense natural disasters like earthquakes early,
Did you know?
- Rhinoceroses can hear sounds as low as 4 Hz.
- Dogs hear from 64 Hz to 23,000 Hz.
- Bats hear from 9,000 Hz to 200,000 Hz.
- Humans hear from 20 Hz to 20,000 Hz.
This is why rhinoceroses are the right answer, they can hear and use infrasound, while the other cannot.
Conclusion: Infrasound is also useful for humans in other ways, like searching for oil, gas, or underground minerals.
