Such sound is called ULTRASOUND. 20,000 Hz (20 kHz) is the approximate upper limit for the human ear.

What kind of sounds have frequencies higher than 20000 Hz?
Ultrasonic. Or do you mean what causes them : all types of electrical machinery including TV sets, humming birds, mice (singing) insects.
What happens when a sounds frequencies higher then 20000Hz?
20,000 Hertz or simply 20 kHz, is taken to be the upper limit of hearing in younger, healthy humans. Sound frequencies higher than 20 kHz cannot be heard by humans, but can be heard by animals like dogs.
Why are some sounds higher pitch than others?
because the pitch is higher
Sound waves with frequencies higher than 20000 Hz are referred to as subsonic waves?
for this answer it's false i made a 90 on this test :)
Objects that vibrate with a high frequency produce sounds with a high what?
Higher frequencies produce the perception of higher pitch sound. A woman's voice generally contains sounds with higher frequencies than a man's voice contains. An infant's voice contains higher frequencies than an adult's voice does.
Does a 400 hertz wave have a higher energy than a 800 hertz wave?
No. The higher the frequency of a wave, the higher the energy.
Do gamma rays have higher frequencies than radios?
Yes, on the order of 1013 hertz higher.

Can dogs detect higher and lower sounds than humans?
yes dogs can detect lower or higher sounds than humans
What happens when a sounds frequencies higher then 20000Hz?
20,000 Hertz or simply 20 kHz, is taken to be the upper limit of hearing in younger, healthy humans. Sound frequencies higher than 20 kHz cannot be heard by humans, but can be heard by animals like dogs.
Who has a higher frequency infrared or ultraviolet?
Ultraviolet rays have higher frequency (1 x 1016 to 8 x 1014 hertz) than the infrared rays(4 x 1014 to 1 x 1013 hertz).
Is Hz higher than MHz or GHz?
No. Hz is the basic unit. MHz is "mega hertz," and mega means 1,000,000. GHz is "giga hertz" and giga means 1,000,000,000.
Why are some sounds higher pitch than others?
because the pitch is higher
Can frogs hear higher or lower sounds than humans?
they can here higher sound than a human
Would you expect a piccolo to produce higher or lower sounds than a flute?
Higher
Are there sounds we can not hear?
Human hearing is most effective in the range of about 20 Hz to 20,000 Hz. Slightly lower frequency sounds may be heard or "felt." Some sounds outside this range can be heard by some individuals. Some animals have a wider range of hearing, such as dogs who can hear higher pitched (higher frequency) sounds.
Dogs can hear from what hertz to what hertz?
I researched this question and apparently: "Dogs hear high tones in particular much better than humans do. Humans can pick up an average of 20,000 acoustic vibrations per second (kHz), whereas a dog is able to perceive between 40,000 and 100,000 vibrations." Although dogs can hear pretty well compared to humans, bats can detect twice as high a pitch as dogs.
