Infrasonic waves are also used in identifying possible locations of oil and natural gas sources. These animals can even and feel sound waves, their hearing is so sensitive that they can even provide early warning for earthquakes or any natural calamity. Whales and dolphins are known to use infrasonic waves to navigate and elephants use them to attract their mates. Our physical world is full of infrasonic sounds, for example, sonic boom produced in jet engines sounds produced by volcanoes, earthquakes, thunderstorms, crashing of ocean waves etc.Ī lot of animals also communicate via infrasonic sound waves such as Whales, dolphins, elephants, hippos. For a dog, the lower limit of the frequency range is 67 Hz. They can communicate via infrasonic sounds.įor Human Beings, the hearing frequency range is about 20 to 20,000 Hz for a healthy person.so evidently, a human cannot hear infrasound and neither a dog nor a bat. Rhinoceros have extremely good ears and thus they are known as infrasonic animals. So, it can only be heard and emitted by those living organisms who are sensitive to frequency range below 20 Hz. Hint: Infrasound is a low-frequency sound that is below 20Hz of the frequency range.
