20Hz to 20khz Real sound 1kHz one kilohertz 1000 HzHertz

One kilohertz abbreviated kHz is equal to 1000 hertz. Like hertz kilohertz is used to measure frequency or cycles per second. Since one hertz is one cycle per second one kilohertz is equal to 1000 cycles per second. Kilohertz is commonly used to measure the frequencies of sound waves since the audible spectrum of sound frequencies is between 20 Hz and 20 kHz. For example middle C C4 on a piano keyboard produces a frequency of 261.63 Hz. The C key two octaves above middle C C6 produces a frequency of just over 1 kHz 1046.5 Hz. Since the sound frequency doubles with each octave the C7 key produces an audible frequency of just over 2 kHz 2093 Hz. As you might guess frequencies above 2 kHz sound very high-pitched. Sound waves and low frequency radio waves are often measured in kilohertz. Other waves such as high frequency radio waves visible light waves and ultraviolet rays have much higher frequencies. Therefore most waves in the electromagnetic spectrum are measured in megahertz gigahertz or even greater units of measurements. Abbreviation: kHz Follow me on Facebook.comMrj.Mahim,
