25per|ceived noise decibel — «puhr SEEVD», a standard unit for measuring noise as perceived by people, based on the type of sound and its intensity: »Airplane noise is measured in perceived noise decibels (New York Times). Abbr: PNdB or PNdb (no periods) …
26Image noise — Noise clearly visible in an image from a digital camera Image noise is random (not present in the object imaged) variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the… …
27Relative intensity noise — (RIN), describes the instability in the power level of a laser. The noise term is important to describe lasers used in fiber optic communication and LIDAR remote sensing.Relative intensity noise can be generated from cavity vibration,… …
28Shot noise — Photon noise simulation. Shot noise is a type of electronic noise that may be dominant when the finite number of particles that carry energy (such as electrons in an electronic circuit or photons in an optical device) is sufficiently small so… …
29Sound intensity — The sound intensity, I , (acoustic intensity) is defined as the sound power Pac per unit area A . The usual context is the noise measurement of sound intensity in the air at a listener s location. For instantaneous acoustic pressure p inst( t )… …
30Signal-to-noise ratio — For signal to noise ratio in statistics, see Cohen s d. Signal to noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined… …
