In acoustic sound, the range of human hearing is from 0 Hz to roughly 20 kHz (depending on many factors, including age and how loud the drummer in your high school rock band played!). The pitch of Middle C on a piano is 263 Hz. Hertz is also used frequently when describing the individual bands of an audio equalizer.
