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.
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.
Infrasonic.'Subsonic' and 'infrasonic' both define sound too low (in frequency or pitch) to be heard by humans without assistance.However, as 'subsonic' can also mean something traveling slower than the speed of sound, and 'infrasonic' only means frequencies below the audible range, 'infrasonic' is the better answer.

radio stations operating at various frequencies.
The antonym for subsonic is supersonic.
It is used in medical instruments to remove 50-60hz frequencies....

Subsonic means "slower than the speed of sound" so a subsonic bullet is any bullet that travels slower than the 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.
