Human hearing range is around 20 Hz to 20,000Hz. So most things under 20Hz
Yes. Very. Humpback whales can be heard for miles underwater by other whales. The frequencies that they "sing" at are just too low for humans to hear most of the time, so we think that they are quiet.
Humans cannot hear ultrasonic (above 20,000 Hz) and infrasonic (below 20 Hz) waves. Ultrasonic waves are too high in frequency for the human ear to detect, while infrasonic waves are too low.
Yes, humans hunt too many blue whales. Japan and Norway in particular need to stop whaling
For humans it is, because most of the sound is at frequencies too low for us to hear.
The term for any sound that is too high for humans to hear is "ultrasonic."
They are, but they are classified as mammals. Humans are mammals, too.
Sound waves that are too low to hear are referred to as infrasound. These waves have frequencies below the threshold of human hearing, typically below 20 Hz. Even though we cannot hear them, infrasound waves can still have effects on humans and animals.
Sounds too low for humans to hear are known as infrasound. These sounds have frequencies below 20 Hz, which is below the threshold of human hearing. Infrasound can be produced by natural events like earthquakes and volcanic eruptions, as well as man-made sources such as heavy machinery and explosions. While we cannot hear them, infrasound can still have physical effects on the body and may be sensed by animals.
Blue whales do not eat humans; they eat krill filtered from the water with their baleen. Humans are too large for them to bite and eat.
Most animals can, but dogs can definitely hear them.
Bats. They are blind and use echolocation to navigate when they are flying. They emit high pitched sounds humans ears are unable to hear. The sound frequency in a human voice is too low pitched for them to hear.
Frequencies that are too low for people to hear are called infrasound. These low-frequency sounds typically range from 0 to 20 Hz and are often felt rather than heard.
