What is a word that means pitches above (or below) the range of human perception? [closed]

See the title. This would be analogous to "ultraviolet" and "infrared" for color.

Solution 1:

Sonic describes sounds. So you would use Ultra or Infra combined with Sonic.

Ultrasonic(ul-tra-son-ic):

of or involving sound waves with a frequency above the upper limit of human hearing.

Infrasonic (in-fra-son-ic):

relating to or denoting sound waves with a frequency below the lower limit of human audibility.

Both definitions come from the Oxford Dictionary of English.

Solution 2:

You probably mean ultrasound:

• (General Physics) ultrasonic waves at frequencies above the audible range (above about 20 kHz), used in cleaning metallic parts, echo sounding, medical diagnosis and therapy, etc.
