What and what are the sound that we Cannot hear?
A wind turbine, a roaring crowd at a football game, a jet engine running full throttle: Each of these things produces sound waves that are well below the frequencies humans can hear.

- Thaumastochelidae (blind deep-sea lobsters)

What are sounds that cannot be heard by human beings?
Sounds with a frequency lower than 20 Hz cannot be heard by humans and are referred to as infrasonic. Such signals start below 20 Hz, but can be detected at frequencies as low as a hundredth or even a thousandth of a hertz.
Why Cant I hear audio on Windows 10?

What is sound not heard by human ear?
The phenomenon is called spontaneous otoacoustic emissions, SOAEs. The whistling sounds cannot be picked up by the human ear and were detected with a microphone. The researchers found that after being exposed to low frequency sounds for 90 seconds, the whistling sounds or SOAEs changed.
Why can’t I hear audio on my computer?
