No. Such sounds are suprsonic sounds.
for this answer it's false i made a 90 on this test :)
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.
Ultrasonic waves are sound waves with frequencies higher than what humans can hear. Sound waves have frequencies of about 20,000 to 100,000.
frequencies higher than 20 kHz are called ultra sound or ultra sonic sound.
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.

The relative highness or lowness of sound is referred to as pitch. Sounds with higher frequencies are perceived as higher-pitched, while sounds with lower frequencies are perceived as lower-pitched. Sounds with the same frequency are perceived as having the same pitch.
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.
Subsonic means "slower than the speed of sound" so a subsonic bullet is any bullet that travels slower than the speed of sound.
Ultrasonic waves are sound waves with frequencies higher than what humans can hear. Sound waves have frequencies of about 20,000 to 100,000.
Transonic being past the speed of sound and subsonic is below the speed of sound.
frequencies higher than 20 kHz are called ultra sound or ultra sonic sound.
subsonic is moving below the speed of sound, supersonic is faster than speed of sound
Another term for this is infrasonic, and it means pertaining to below hearing. There natural frequencies that humans can hear which are high: 20,000 Hz and low: 20 Hz. An average human cannot hear sounds below the frequency of 20 Hz. That is subsonic. Subsonic is a term also applied to aircraft that travel at speeds less than the speed of sound. Supersonic means it travels faster than the speed of sound.
sounds that are below 20hz are called INFRASONIC/Subsonic. These kinds of frequencies are used by the military for experiments.

Do you mean the wavelength? Sound of higher frequencies has a shorter wavelength.
Basically, is a device which measures the amplitude and frequencies of a sound wave. It is shown on a screen. Closer waves, higher frequencies. Longer waves, lower frequencies.
