The Frequency of Sound

- Oct 10, 2018-

The number of times a sound wave vibrates per second, called the frequency. Recorded as F, the unit is Hz (period/S). The human ear can hear from 20Hz to 20,000Hz. As the age increases, the human hearing range gradually decreases toward the middle and low frequencies. Good music programs are available in a variety of frequencies from 40 to 16,000 Hz.
