While 20 to 20,000Hz forms the absolute borders of the human hearing range, our hearing is most sensitive in the 2000 - 5000 Hz frequency range. As far as loudness is concerned, humans can typically hear starting at 0 dB.

Named after Heinrich Hertz, hertz is a unit of frequency that defines the number of cycles per second of a periodic phenomenon. When applied to monitors, it basically means that 1 hertz = 1 frame per second. The higher the Hz, the more frames your monitor can display per second.

One hertz, or Hz, means that the frequency is one cycle per second. Kilohertz, or kHz, refers to how many thousands of cycles occur per second. Megahertz, or MHz, refers to millions, gigahertz, or GHz, refers to billions and terahertz, or THz refers to trillions of cycles per second.

The frequency or amount of air pressure change vibration is measured in Hertz. The resulting change in air pressure created through the vibrating object is measured in decibels. Decibels, in effect, measure the loudness of a sound and Hertz measures the frequency of the sound.

Gigahertz (GHz) is a frequency unit that measures the number of cycles per second. Hertz (Hz) refers to the number of cycles per second with periodic 1-second intervals. One megahertz (MHz) equals 1,000,000 Hz. One gigahertz is equal to 1,000 megahertz (MHz) or 1,000,000,000 Hz.

Kilohertz. One kilohertz (abbreviated "kHz") is equal to 1,000 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 1,000 cycles per second.

Decibel is the proportional unit of sound volume. The lowest sound audible with a normal (average) hearing is 0 dB (2 ∙ 10-5 pascals as a sound pressure value or 10-12 W/m2 as an intensity value at 1000 Hz). A person with good hearing can hear even weaker sounds (-5 dB).

The decibel (dB) is one-tenth of a bel: 1 dB = 0.1 B.
1098295
Decibel (dB), unit for expressing the ratio between two physical quantities, usually amounts of acoustic or electric power, or for measuring the relative loudness of sounds. One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio.

For any device that uses a standard speaker driver, the Hz-KHz value is the range of audible sound vibrations that the speaker can produce. It's generally labeled as the “frequency response” and expressed in hertz, with kilohertz being a thousand hertz.

Harmonics are integer multiples of the fundamental frequency. For example, if the fundamental frequency is 50 Hz (also known as the first harmonic) then the second harmonic will be 100 Hz (50 * 2 = 100 Hz), the third harmonic will be 150 Hz (50 * 3 = 150 Hz), and so on.

One kilohertz (abbreviated "kHz") is equal to 1,000 hertz. ... Since one hertz is one cycle per second, one kilohertz is equal to 1,000 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.

1 Hertz means one vibration cycle per second, 50 Hertz means 50 vibration cycles per second while 60 Hertz means 60 vibration cycles per second. Hz is a very small unit, usually coupled with kHz (kilohertz), MHz (Megahertz), GHz (Gigahertz) etc.

One gigahertz equals 1,000,000,000 Hz or 1,000 MHz and has a frequency measurement with periodic 1-second cycles. A nanosecond is one-billionth of a second or one-thousandth of a microsecond.

Human ear perceives frequencies between 20 Hz (lowest pitch) to 20 kHz (highest pitch).
