subaudible
Too low-pitched
Subaudible describes sounds that fall below the threshold of human hearing, typically frequencies under about 20 hertz.
These low-frequency vibrations exist but cannot be perceived by the ear, though they may sometimes be felt physically.
The term appears in technical contexts involving acoustics, audio engineering, and seismology.
The subaudible tones were detected only by specialized equipment.
