Frequencies above 20kHz are not audible to humans. Sounds above this frequency are called ultrasound.
sounds that are below 20hz are called INFRASONIC/Subsonic. These kinds of frequencies are used by the military for experiments. If you used Subsonic Frequencies below 20hz in I-dosing, You would have catastrophic cell death in every organ, causing them to shoot blood up into the mouth, and it also triggers your nerves to preform involuntary muscle movements, and death will come anywhere from 10-20 Sec. In other words, (My favourite phrase about subsonic frequencies,) Hertz Hurts.
Infrasounds (frequencies under 20 kHz)
They're called "subsonic".That makes sense. "Sub" means "under", and "sonic" refers to "sound"."Subsonic" waves are those with frequencies lower than sounds audibleto the human ear.
No. Such sounds are suprsonic sounds.

Audible sounds - are those that fall within the scope of human hearing. These are sounds that are typically in the frequency range of 50 Hz to 20 kHz. Frequencies below 50 Hz are classed as ULF (ultra-low frequency) sounds. Those above 20kHz are labelled as ultrasonic sounds.
Anything above 20 KHz is, although the medical ultrasound systems operate with sounds up into the megahertz.
The frequencies of sounds that can be heard by most people are between 20 and 20,000 Hz. Sounds outside of this range are possible, but can no longer be heard by humans.
I think what you mean is: What frequencies correspond to sounds heard by humans ?The answer to that one is different for every individual. A representative bandwidth for humansis commonly considered to be 20 Hz to 20,000 Hz.
yes and no... depends on how close the source is...
Sounds in this range are known as ultrasound. They have frequencies from about 20 kHz to a few GHz. Even the sounds at the low-frequency end are beyond the ability of most people to hear.
