百科释义
Infrasound, sometimes referred to as low-frequency sound, is sound that is lower in frequency than 20?Hz (Hertz) or cycles per second, the "normal" limit of human hearing. Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high.
