Decibel vs. Hertz
Decibelnoun
A common measure of sound intensity ratio that is one tenth of a bel on the logarithmic intensity scale. It is defined as dB = 10 log10(P1 / P2), where P1 and P2 are the relative powers of the sound.
Decibelnoun
a logarithmic unit of sound intensity; 10 times the logarithm of the ratio of the sound intensity to some reference intensity
Decibel
The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale.
Hertznoun
In the International System of Units, the derived unit of frequency; one (period or cycle of any periodic event) per second. Symbol: Hz
Hertznoun
a unit of frequency equal to one cycle per second; it is abbreviated Hz. It is commonly used to specify the frequency of radio waves, and also the clock frequencies in digital computers. For these applications, kilohertz and megahertz are the most commonly used units, derived from hertz.
Hertznoun
the unit of frequency; one Hertz has a periodic interval of one second
Hertznoun
German physicist who was the first to produce electromagnetic waves artificially (1857-1894)
Hertznoun
German physicist who with James Franck proved the existence of the stationary energy states postulated by Bohr (1887-1975)
Hertznoun
the SI unit of frequency, equal to one cycle per second.
Hertz
The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units (SI) and is defined as one cycle per second. It is named after Heinrich Rudolf Hertz (1857-1894), the first person to provide conclusive proof of the existence of electromagnetic waves.
