- Sounds that are too low-pitched to be consciously perceived by humans are called infrasound or subsonic. Subsonic sound has an effect on human hearing. The frequency range of normal human hearing is 20-24,000 Hz. Researchers have found that frequences as low as 1 Hz (one cycle per second) have a definite effect on the inner ear, affecting its equilibrium and causing dizziness.
