subsonic is lower than 20Hz, and hypersonic(aslo called ultrasonic freq.)is higher than 14000Hz-16000Hz(you cant hear ultrasonic freq.,some people hear 50-14000,some 150-16000, even some like me hear 20-16500)my specter of hearing freq.is 32-16347Hz(I have been on tests)

What are subsonic signals?
Subsonic signals are sounds or vibrations that have a frequency lower than that which may be heard by the human ear as a discernable tone. Vibrations lower than 30 Hz (30 cycles per second) are considered subsonic.
What are sounds with frequencies below 20 hertz called?
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.
What's difference between subsonic and supersonic?
Subsonic is below or slower than the speed of sound, and supersonic is above or faster than the speed of sound.

Why doesn't a subsonic aircraft produce a sonic boom?
A subsonic aircraft doesn't produce a sonic boom because it is subsonic, and cannot produce enough speed to do so. A sonic boom is created when an aircraft becomes supersonic, accelerating past the speed of sound. Since it is traveling near the speed of sound at this time, the sound waves build up around it, finally traveling through the air as it is left behind by the aircraft.
What is the antonym of subsonic?
You could use "hypersonic." It is not a precise synonym, as subsonic is below the threshhold of hearing, whereas hypersonic would be above it. Supersonic would refer to velocity faster than the speed of sound, whereas subsonic also refers to velocities slower than those of the speed of sound. Sonic velocities are a consideration in jet aircraft design and with bullets and marksmanship. Subsonic rifle bullets tend to be more accurate than hypersonic ones
What are subsonic signals?

When was Hypersonic XLC created?
Hypersonic XLC was created in 2001.
What frequency is consider subsonic?
Vibrations below 20 cycles per second (less than 20 Hz) we cannot hear, but we can feel them.
What is the duration of Hypersonic XLC?
The duration of Hypersonic XLC is 16.0 seconds.
What kind of sound is made by low frequency vibrations?
Low frequency sound is usually called "infrasound" analagous to the term "infrared" for light of less than visible wavelengths. Subsonic has also been used.
What is the antonym for the word subsonic?
The antonym for subsonic is supersonic.
What is supersonic and hypersonic?
Supersonic and hypersonic are speeds. Supersonic means faster than the speed of sound, and hypersonic means very much faster.
What is the duration of Hypersonic Flight Experiment?
The duration of Hypersonic Flight Experiment is 120.0 seconds.
What has the author Wayland C Griffith written?
Wayland C. Griffith has written: 'Hypersonic nozzle design' -- subject(s): Aerodynamics, Hypersonic, Aeronautical laboratories, Hypersonic Aerodynamics, Hypersonic nozzles, Research 'The effect of Reynolds number on the diffraction of a shock wave'

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