What are sounds below 20 Hz called?

At the other end of the spectrum are very low-frequency sounds (below 20 Hz), known as infrasound. Elephants use infrasound for communication, making sounds too low for humans to hear. Because low frequency sounds travel farther than high frequency ones, infrasound is ideal for communicating over long distances.

Is 20 Hz audible?

Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz. (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.)

What frequency do dogs hate?

At sufficient volumes, frequencies above 25,000 Hz become irritating for dogs. The louder and higher those sounds are, the more uncomfortable for the dog they become. Dogs may whimper, whine and run away if confronted with a sufficiently loud and high-frequency sound.
