What is the sound waves of frequencies above 20 k hz is called?

Frequencies above 20kHz are not audible to humans. Sounds above this frequency are called ultrasound.


What are sound waves below 20 Hz called?

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.


What are Frequencies below 20 Hz?

infrasounds


What Sound waves below 20 waves per second called?

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.


What are sound waves with frequencies below normal range?

Infrasounds (frequencies under 20 kHz)


Are sound waves with frequencies higher than 20 000 Hz referred to as subsonic waves?

No. Such sounds are suprsonic sounds.


What is inaudible and audible sounds in detail?

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.


What are the frequencies that are considered ultrasonic sounds?

Anything above 20 KHz is, although the medical ultrasound systems operate with sounds up into the megahertz.


What are the Example of sounds of frequency?

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.


What sounds correspond to frequencies 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.


Can the sounds of frequencies less than 20 Hz hurt your ears?

yes and no... depends on how close the source is...


What sounds have the greatest frequency?

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.
