The range of normal human hearing is 20 Hertz (Hz) to 20,000 Hz (20 kHz). Sound waves below this frequency range (<20 Hz) are called infrasound
Human ear perceives frequencies between 20 Hz (lowest pitch) to 20 kHz (highest pitch). All sounds below 20 Hz are qualified as infrasounds, althought some animals (ex. mole-rat, or elephant) are hearing them.
