  • Although the human ear collects sounds up to 20 kHz (1 kilohertz = 1000 hertz), the 2-5 kHz frequency range is where most of the spectral cues (the frequency of the sound) for speech are found.

  • 1 kilohertz

Examples

  • As with any electronic shortcut, there are a few drawbacks: the clock cycle feeding into the flip-flop has to be pretty fast; at least a few dozen kilohertz if you're sampling audio.

Morphology

kilohertz = hertz (transparent) = kilo + hertz + kilo

Standard SI prefix 'kilo-' (one thousand) attached to the unit 'hertz' yields a straightforward meaning 'one thousand hertz'.

Etymology

Kilohertz combines kilo-, meaning 'thousand' as in kilogram, with hertz, the unit named after the scientist Heinrich Hertz meaning 'cycles per second'. So a kilohertz is simply a thousand hertz, or a thousand 'cycles per second'.
