The lowest frequency audible to humans is typically around 20 cycles per second, which is also known as 20 hertz (Hz). This is the bottom end of the range of frequencies that make up the audible spectrum. Frequencies below this range are called infrasound and can be felt more than heard, while frequencies above this range are called ultrasound and are also typically inaudible to humans.
