2. Dark current (physics) - Wikipedia

   en.wikipedia.org/wiki/Dark_current_(physics)

   Dark current is one of the main sources for noise in image sensors such as charge-coupled devices. The pattern of different dark currents can result in a fixed-pattern noise ; dark frame subtraction can remove an estimate of the mean fixed pattern, but there still remains a temporal noise, because the dark current itself has a shot noise .

3. Noise curve - Wikipedia

   en.wikipedia.org/wiki/Noise_curve

   Noise curves are a common way to characterise background noise in unoccupied buildings and spaces. [1] Their purpose is to produce a single-value representation of a complete sound spectrum. International standards organizations ( ISO , [ 2 ] ANSI [ 3 ] and ASA ) recognize the need to objectify judgements on the amount of ambient noise in ...

4. Noise reduction coefficient - Wikipedia

   en.wikipedia.org/wiki/Noise_reduction_coefficient

   The noise reduction coefficient (commonly abbreviated NRC) is a single number value ranging from 0.0 to 1.0 that describes the average sound absorption performance of a material. An NRC of 0.0 indicates the object does not attenuate mid-frequency sounds, but rather reflects sound energy.

5. Equivalent noise resistance - Wikipedia

   en.wikipedia.org/wiki/Equivalent_noise_resistance

   In telecommunication, an equivalent noise resistance is a quantitative representation in resistance units of the spectral density of a noise-voltage generator, given by = where is the spectral density, is the Boltzmann constant, is the standard noise temperature (290 K), so = [].
