Normal distribution

In probability theory, the normal (or Gaussian) distribution is a continuous probability distribution that has a bell-shaped probability density function, known as the Gaussian function or informally the bell curve: The parameter μ is the mean or expectation (location of the peak) and σ is the variance. σ is known as the standard deviation. The distribution with μ = 0 and σ = 1 is called the standard normal distribution or the unit normal distribution.

Noise music

Noise music is a category consisting of multiple discrete genres of music that have employed noise as a musical resource. It includes a wide range of musical styles, and sound based creative practices, that feature noise as a primary aspect. It can feature acoustically or electronically generated noise, and both traditional and unconventional musical instruments.

Noise rock

Noise rock (also known as noise punk) describes a style of post-punk rock music that became prominent in the 1980s. Noise rock makes use of the traditional instrumentation and iconography of rock, but incorporates atonality and especially dissonance, and also frequently discards usual songwriting conventions.

Cosmic microwave background radiation

In cosmology, cosmic microwave background (CMB) radiation (also CMBR, CBR, MBR, and relic radiation) is thermal radiation filling the observable universe almost uniformly. With a traditional optical telescope, the space between stars and galaxies (the background) is completely dark. However, a sufficiently sensitive radio telescope shows a faint background glow, almost exactly the same in all directions, that is not associated with any star, galaxy, or other object.

Signal-to-noise ratio

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 as the ratio of signal power to the noise power. A ratio higher than 1:1 indicates more signal than noise. While SNR is commonly quoted for electrical signals, it can be applied to any form of signal (such as isotope levels in an ice core or biochemical signaling between cells).

In common use, the word noise means any unwanted sound. In physics and analog electronics, noise is a mostly unwanted random addition to a signal; it is called noise as a generalisation of the acoustic noise ("static") heard when listening to a weak radio transmission with significant electrical noise. Signal noise is heard as acoustic noise if the signal is converted into sound (e.g. , played through a loudspeaker); it manifests as "snow" on a television or video image.


Flatulence is the expulsion through the rectum of a mixture of gases that are byproducts of the digestion process of mammals and other animals. The medical term for the mixture of gases is flatus, informally known as a fart, or simply gas. The gases are expelled from the rectum in a process colloquially referred to as "passing gas", "breaking wind" or "farting". Flatus is brought to the rectum by the same peristaltic process which causes feces to descend from the large intestine.

Channel (communications)

In telecommunications and computer networking, a communication channel, or channel, refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel. A channel is used to convey an information signal, for example a digital bit stream, from one or several senders (or transmitters) to one or several receivers.

Electromagnetic interference

Electromagnetic interference (or EMI, also called radio frequency interference or RFI when in high frequency or radio frequency) is disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source. The disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the circuit. These effects can range from a simple degradation of data to a total loss of data.

Noise pollution

Noise pollution is excessive, displeasing human, animal, or machine-created environmental noise that disrupts the activity or balance of human or animal life. The word noise may be from the Latin word nauseas, which means disgust or discomfort. The source of most outdoor noise worldwide is mainly construction and transportation systems, including motor vehicle noise, aircraft noise, and rail noise.

Noise pollution Sounds by type Audiology
White noise

White noise is a random signal (or process) with a flat power spectral density. In other words, the signal contains equal power within a fixed bandwidth at any center frequency. White noise draws its name from white light in which the power spectral density of the light is distributed over the visible band in such a way that the eye's three color receptors are approximately equally stimulated.

Noise (electronics)

In electronics, noise is a random fluctuation in an electrical signal, a characteristic of all electronic circuits. Noise generated by electronic devices varies greatly, as it can be produced by several different effects. Thermal noise is unavoidable at non-zero temperature, while other types depend mostly on device type (such as shot noise, which needs steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.

Anti-social behaviour

Anti-social behaviour (with or without hyphen) is behaviour that lacks consideration for others and may cause damage to the society, whether intentionally or through negligence. This is opposed to pro-social behaviour, which is behaviour that helps or benefits the society. Criminal and civil laws in various countries offer remedies for anti-social behaviour.

Static random-access memory

Static random-access memory (SRAM) is a type of semiconductor memory that uses bistable latching circuitry to store each bit. The term static differentiates it from dynamic RAM (DRAM) which must be periodically refreshed. SRAM exhibits data remanence, but is still volatile in the conventional sense that data is eventually lost when the memory is not powered.

Tag (metadata)

In information systems, a tag is a non-hierarchical keyword or term assigned to a piece of information (such as an Internet bookmark, digital image, or computer file). This kind of metadata helps describe an item and allows it to be found again by browsing or searching. Tags are generally chosen informally and personally by the item's creator or by its viewer, depending on the system.

Pseudorandom number generator

A pseudorandom number generator (PRNG), also known as a deterministic random bit generator (DRBG), is an algorithm for generating a sequence of numbers that approximates the properties of random numbers. The sequence is not truly random in that it is completely determined by a relatively small set of initial values, called the PRNG's state, which includes a truly random seed.

Wall of Sound

The Wall of Sound is a music production technique for pop and rock music recordings developed by record producer Phil Spector at Gold Star Studios in Los Angeles, California, during the early 1960s. Working with such audio engineers as Larry Levine and the session musicians who became known as The Wrecking Crew, Spector created a dense, layered, reverberant sound that came across well on AM radio and jukeboxes popular in the era.

Drone music

Drone music is a minimalist musical style that emphasizes the use of sustained or repeated sounds, notes, or tone-clusters – called drones. It is typically characterized by lengthy audio programs with relatively slight harmonic variations throughout each piece compared to other musics. La Monte Young, one of its 1960s originators, defined it in 2000 as "the sustained tone branch of minimalism".

Errors and residuals in statistics

In statistics and optimization, statistical errors and residuals are two closely related and easily confused measures of the deviation of a sample from its "theoretical value". The error of a sample is the deviation of the sample from the (unobservable) true function value, while the residual of a sample is the difference between the sample and the estimated function value. The distinction is most important in regression analysis, where it leads to the concept of studentized residuals.

Crosstalk (electronics)

In electronics, crosstalk (XT) is any phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel. Crosstalk is usually caused by undesired capacitive, inductive, or conductive coupling from one circuit, part of a circuit, or channel, to another.

Wiener process

In mathematics, the Wiener process is a continuous-time stochastic process named in honor of Norbert Wiener. It is often called standard Brownian motion, after Robert Brown. It is one of the best known Lévy processes and occurs frequently in pure and applied mathematics, economics and physics. The Wiener process plays an important role both in pure and applied mathematics. In pure mathematics, the Wiener process gave rise to the study of continuous time martingales.

Soundproofing is any means of reducing the sound pressure with respect to a specified sound source and receptor. There are several basic approaches to reducing sound: increasing the distance between source and receiver, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles, or using active antinoise sound generators.

Spectral density

In statistical signal processing and physics, the spectral density, power spectral density (PSD), or energy spectral density (ESD), is a positive real function of a frequency variable associated with a stationary stochastic process, or a deterministic function of time, which has dimensions of power per hertz (Hz), or energy per hertz. It is often called simply the spectrum of the signal.

Sensorineural hearing loss

Sensorineural hearing loss (SNHL) is a type of hearing loss in which the root cause lies in the vestibulocochlear nerve, the inner ear, or central processing centers of the brain. The Weber test, in which a tuning fork is touched to the midline of the forehead, localizes to the normal ear in people with this condition. The Rinne test, which tests air conduction vs. bone conduction is positive (normal), though both bone and air conduction are reduced equally.


Intermodulation or intermodulation distortion (IMD) is the amplitude modulation of signals containing two or more different frequencies in a system with nonlinearities. The intermodulation between each frequency component will form additional signals at frequencies that are not just at harmonic frequencies of either, but also at the sum and difference frequencies of the original frequencies and at multiples of those sum and difference frequencies.

Infrasound is sound that is lower in frequency than 20 Hz or cycles per second, the "normal" limit of human hearing. Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high. The ear is the primary organ for sensing infrasound, but at higher levels it is possible to feel infrasound vibrations in various parts of the body.

Noise reduction

Noise reduction is the process of removing noise from a signal. All recording devices, both analogue or digital, have traits which make them susceptible to noise. Noise can be random or white noise with no coherence, or coherent noise introduced by the device's mechanism or processing algorithms. In electronic recording devices, a major form of noise is hiss caused by random electrons that, heavily influenced by heat, stray from their designated path.

A noise gate or gate is an electronic device or software that is used to control the volume of an audio signal. Gating is the use of a gate. Comparable to a compressor, which attenuate signals above a threshold, noise gates attenuate signals which register below the threshold. However, noise gates attenuate signals by a fixed amount, know as the range. In its most simple form, a noise gate allows a signal to pass through only when it is above a set threshold: the gate is 'open'.

If no noise were picked up with radio signals, even weak transmissions could be received at virtually any distance by making a radio receiver that was sensitive enough.

Noise floor

In signal theory, the noise floor is the measure of the signal created from the sum of all the noise sources and unwanted signals within a measurement system, where noise is defined as any signal other than the one being monitored. In radio communication and electronics, this may include thermal noise, blackbody, cosmic noise as well as atmospheric noise from distant thunderstorms and similar and any other unwanted man made signals, sometimes referred to as incidental noise.

ITU-R 468 noise weighting

ITU-R 468 (originally defined in CCIR recommendation 468-4) is a standard relating to noise measurement, widely used when measuring noise in audio systems. The standard defines a weighting filter curve, together with a quasi-peak rectifier having special characteristics as defined by specified tone-burst tests. It is currently maintained by the European Broadcasting Union who took it over from the CCIR.

Low-noise amplifier

Low-noise amplifier (LNA) is an electronic amplifier used to amplify possibly very weak signals (for example, captured by an antenna). It is usually located very close to the detection device to reduce losses in the feedline. This active antenna arrangement is frequently used in microwave systems like GPS, because coaxial cable feedline is very lossy at microwave frequencies, e.g. a loss of 10% coming from few meters of cable would cause a 10% degradation of the signal-to-noise ratio (SNR).

Colors of noise

While noise is by definition derived from a random signal, it can have different characteristic statistical properties corresponding to different mappings from a source of randomness to the concrete noise. Spectral density is such a property, which can be used to distinguish different types of noise. This classification by spectral density is given "color" terminology, with different types named after different colors, and is common in different disciplines where noise is an important factor.

Bruit is the term for the unusual sound that blood makes when it rushes past an obstruction in an artery when the sound is auscultated with the bell portion of a stethoscope. The term "bruit" simply refers to the sound. A related term is "vascular murmur", which should not be confused with a heart murmur. The location of the stethoscope when the sound is observed can affect the diagnosis.

Noise shaping

Noise shaping is a technique typically used in digital audio, image, and video processing, usually in combination with dithering, as part of the process of quantization or bit-depth reduction of a digital signal. Its purpose is to increase the apparent signal to noise ratio of the resultant signal.

Automotive aerodynamics

Automotive aerodynamics is the study of the aerodynamics of road vehicles. The main concerns of automotive aerodynamics are reducing drag (though drag by wide wheels is dominating most cars), reducing wind noise, minimizing noise emission, and preventing undesired lift forces and other causes of aerodynamic instability at high speeds. For some classes of racing vehicles, it may also be important to produce desirable downwards aerodynamic forces to improve traction and thus cornering abilities.

Pseudorandom noise

In cryptography, pseudo random noise (PRN) is a signal similar to noise which satisfies one or more of the standard tests for statistical randomness. Although it seems to lack any definite pattern, pseudo random noise consists of a deterministic sequence of pulses that will repeat itself after its period. In cryptographic devices, the pseudo random noise pattern is determined by a key and the repetition period can be very long, even millions of digits.

Gaussian noise

Gaussian noise is statistical noise that has its probability density function equal to that of the normal distribution, which is also known as the Gaussian distribution. In other words, the values that the noise can take on are Gaussian-distributed. A special case is white Gaussian noise, in which the values at any pairs of times are statistically independent. In applications, Gaussian noise is most commonly used as additive white noise to yield additive white Gaussian noise.

A quiet PC is a personal computer that makes little noise. Common uses for quiet PCs include video editing, sound mixing, home servers, and home theater PCs. A typical quiet PC uses quiet cooling and storage devices and energy-efficient parts. Like noise, the term "quiet PC" is subjective and there is currently no standard definition for a "quiet PC". However, a general definition proposed by one site is that the sound emitted by such PCs should not exceed 30 dBA.

Noise-cancelling headphones are any headphones that reduce unwanted ambient sounds by means of active noise control (ANC). This involves using one or more microphones placed near the ear, and electronic circuitry which uses the microphone signal to generate an "antinoise" signal. When the antinoise signal is produced by the speaker driver in the headphone, destructive interference cancels out the ambient noise as heard within the enclosed volume of the headphone.

Carrier-to-noise ratio

In telecommunications, the carrier-to-noise ratio, often written CNR or C/N, is the signal-to-noise ratio (SNR) of a modulated signal. The term is used to distinguish the CNR of the radio frequency passband signal from the SNR of an analogue base band message signal after demodulation, for example an audio frequency analogue message signal. If this distinction is not necessary, the term SNR is often used instead of CNR, with the same definition.

Noise control

Noise control is an active or passive means of reducing sound emissions, often incentivised by personal comfort, environmental considerations or legal compliance. Practical and efficient noise control is wholly reliant on an accurate diagnosis of what is causing the noise, which first involves finding the source of noise. Once the source of noise has been found, the focus is reducing the noise at source by engineering means.

Peak signal-to-noise ratio

The phrase peak signal-to-noise ratio, often abbreviated PSNR, is an engineering term for the ratio between the maximum possible power of a signal and the power of corrupting noise that affects the fidelity of its representation. Because many signals have a very wide dynamic range, PSNR is usually expressed in terms of the logarithmic decibel scale. The PSNR is most commonly used as a measure of quality of reconstruction of lossy compression codecs.

Impulse noise (audio)

Impulse noise is a category of noise which includes unwanted, almost instantaneous sharp sounds (like clicks and pops). Noises of the kind are usually caused by electromagnetic interference, scratches on the recording disks, and ill synchronization in digital recording and communication. High levels of such a noise (200 + Decibels) may damage internal organs, while 180 Decibels are enough to destroy or damage human ears.

Carrier-to-receiver noise density

In satellite communications, carrier-to-receiver noise density (C/kT) is the ratio of the received carrier power to the receiver noise power density. The carrier-to-receiver noise density ratio is usually expressed in dBHz. The carrier-to-receiver noise density is given by where C is the received carrier power in watts, k is Boltzmann's constant in joules per kelvin, and T is the receiver system noise temperature in kelvins.

Noise-equivalent power

Noise-equivalent power (NEP) is a measure of the sensitivity of a photodetector or detector system. It is defined as the signal power that gives a signal-to-noise ratio of one in a one hertz output bandwidth. An output bandwidth of one hertz is equivalent to half a second of integration time. The units of NEP are watts per square root hertz. The NEP is equal to the noise spectral density (expressed in units of or) divided by the responsivity (expressed in units of or, respectively).

Rumble (noise)

A rumble is a form of low-frequency noise created by a random sound wave existing between certain limitation points. In audio rumble refers to a low frequency sound from the bearings inside a turntable. This is most noticeable in low quality turntables with ball bearings. Higher quality turntables use slide bearings, minimizing rumble. Some phono pre-amplifiers implement a rumble filter, in an attempt to remove the noise. A heavier platter can also help dampen this.

Effective input noise temperature

In telecommunications, effective input noise temperature is the source noise temperature in a two-port network or amplifier that will result in the same output noise power, when connected to a noise-free network or amplifier, as that of the actual network or amplifier connected to a noise-free source. If F is the noise figure numeric and 290 K the standard noise temperature, then the effective noise temperature is given by T n = 290(F-1).

Noise (audio)

Noise in audio, recording, and broadcast systems refers to the residual low level sound (usually hiss and hum) that is heard in quiet periods of a programme. In audio engineering it can refer either to the acoustic noise from loudspeakers, or to the unwanted residual electronic noise signal that gives rise to acoustic noise heard as 'hiss'. This signal noise is commonly measured using A-weighting or ITU-R 468 weighting Noise is often generated deliberately and used as a test signal.

CX (audio)

CX is a noise reduction system for recorded analog audio. It was developed by CBS Laboratories (a division of CBS) in the 1970s as a competitor to other noise reduction (NR) systems such as Dolby and dbx. The name CX was derived from "Compatible eXpansion," a feature of the technique. CX was originally designed by CBS as a noise-reduction technology for vinyl LP records. CX required a special decoder connected to a stereo system, in order to fully reproduce the CX encoded sound on the LP.

Noise measurement

Noise measurement is carried out in various fields. In acoustics, it can be for the purpose of measuring environmental noise, or part of a test procedure using white noise, or some other specialised form of test signal. In electronics it relates to the sensitivity of communications systems, the purity of signals, or the quality of audio systems. The concept is to define the noise level below which signals cannot reliably be detected.

Noise spectral density

In communications, noise spectral density N0 is the noise power per unit of bandwidth; that is, it is the power spectral density of the noise. It has dimension of power/frequency, whose SI coherent unit is watts per hertz, which is equivalent to watt-seconds or joules. If the noise is white noise, i.e. , constant with frequency, then the total noise power N in a bandwidth B is BN0. This is utilized in signal-to-noise ratio calculations.

Perceptual noise exclusion hypothesis

The concept of a perceptual noise exclusion deficit is an emerging hypothesis as to the origins and nature of dyslexia. It is supported by research showing that dyslexic adults and children experience difficulty in targeting visual information in the presence of visual perceptual distractions, but subjects do not show the same impairment when the distracting factors are removed in an experimental setting.

Modulated Noise Reference Unit

MNRU redirects here. It can also refer to the United Revolutionary Nationalist Movement. Modulated Noise Reference Unit (MNRU) is an ITU standard (ITU P.810). The MNRU is, as the name implies, a noise model that utilizes speech as well as noise as input. The modulated output noise is a result of a combination of the input speech and noise, where the input speech is used to modulate the input noise. MNRU is mainly used in the telecommunication industry.

Reference noise

In telecommunication, reference noise is the magnitude of circuit noise chosen as a reference for measurement. Many different levels with a number of different weightings are in current use, and care must be taken to ensure that the proper parameters are stated. Specific ones include: dBa, dBa(F1A), dBa(HA1), dBa0, dBm, dBm(psoph), dBm0, dBrn, dBrnC, dBrnC0, dBrn(f1-f2), dBrn(144-line), dBx.

A Cellarful of Noise

A Cellarful of Noise is the title of Brian Epstein's 1964 autobiography. His assistant, Derek Taylor, was the ghostwriter of the book, which describes the early days of The Beatles, whom Epstein managed. Epstein asked John Lennon what he thought the book should be called, and Lennon suggested "Queer Jew". Lennon was later quoted as saying that the book should have been titled, "A Cellarful of Boys" in reference to Epstein's homosexuality.

Noise trader

A noise trader also known informally as idiot trader is described in the literature of financial research as a stock trader whose decisions to buy, sell, or hold are irrational and erratic. The presence of noise traders in financial markets can then cause prices and risk levels to diverge from expected levels even if all other traders are rational.

Eb/N0 (the energy per bit to noise power spectral density ratio) is an important parameter in digital communication or data transmission. It is a normalized signal-to-noise ratio (SNR) measure, also known as the "SNR per bit". It is especially useful when comparing the bit error rate (BER) performance of different digital modulation schemes without taking bandwidth into account.

Circuit noise level

Circuit noise level: At any point in a transmission system, the ratio of the circuit noise at that point to an arbitrary level chosen as a reference. Note: The circuit noise level is usually expressed in dBrn0, signifying the reading of a circuit noise meter, or in dBa0, signifying circuit noise meter reading adjusted to represent an interfering effect under specified conditions.

Oscillator phase noise

Oscillators inherently produce high levels of phase noise. That noise increases at frequencies close to the oscillation frequency or its harmonics. With the noise being close to the oscillation frequency, it cannot be removed by filtering without also removing the oscillation signal. And since it is predominantly in the phase, it cannot be removed with a limiter.

Black Noise (group)

Black Noise is a hip-hop crew hailing from the Cape Flats in Cape Town, South Africa. The crew, along with Prophets of da City (POC), is credited with being a pioneer of Cape Town's 'conscious' hip-hop scene in the late 80s and early 90s. The crew's line-up has changed significantly since the early 90s, but Emile YX? (aka Emile Jansen) has been the crew's mainstay.

Mode partition noise

Mode partition noise: In an optical communication link, is phase jitter of the signal caused by the combined effects of mode hopping in the optical source and intramodal distortion in the fiber. Mode hopping causes random wavelength changes which in turn affect the group velocity, i.e. , the propagation time. Over a long length of fiber, the cumulative effect is to create jitter, i.e. mode partition noise. The variation of group velocity creates the mode partition noise.

White Noise (song)

Channel noise level

In telecommunications, the term channel noise level has the following meanings: The ratio of the channel noise at any point in a transmission system to an arbitrary level chosen as a reference. The noise power spectral density in the frequency range of interest. The average noise power in the frequency range of interest.

White noise (slang)

The term white noise, the 'sh' noise produced by a signal containing all audible frequencies of vibration, is sometimes used as slang to describe a meaningless commotion or chatter that masks or obliterates underlying information. The information itself may have characteristics that achieve this effect without the need to introducing a masking layer. A common example of this usage is a politician including more information than needed to mask a point he doesn't want noticed.

The Noise Next Door

The Noise Next Door is a three piece band, made up of triplet brothers from Leigh Park, England. Craig, Scott and Ed Sutton were born on 30 May 1986, to Annette and Barry Sutton. They were the final three of an already large family consisting of four girls. Their father, Barry, is a musician, and the three boys started a band at the age of thirteen called 'Trips'. In 2004 John McLaughin, who has written for Busted, Blue and Sugababes, discovered them working in their local Asda.

Noise (economic)

Economic noise, or simply noise, describes a theory of pricing developed by Fischer Black. To Black, noise is the opposite of information. Sometimes it's hype, other times it's inaccurate ideas, other times it's inaccurate data; noise has many forms. Noise is everywhere in the economy and we can rarely tell the difference between it and information. Noise has two broad implications. It allows speculative trading to occur (see below). It is indicative of market inefficiency.

Contrast-to-noise ratio

Contrast-to-noise ratio (CNR) is a measure used to determine image quality. CNR is similar to the metric, signal-to-noise ratio (SNR), but subtracts off a term before taking the ratio. This is important when there is a significant bias in an image, such as from haze. As can be seen in the picture at right, the intensity is rather high even though the features of the image are washed out by the haze. Thus this image may have a high SNR metric, but will have a low CNR metric.

Antenna noise temperature

In telecommunication, antenna noise temperature is the temperature of a hypothetical resistor at the input of an ideal noise-free receiver that would generate the same output noise power per unit bandwidth as that at the antenna output at a specified frequency. Antenna noise temperature has contributions from several sources: Galactic radiation Earth heating The sun Electrical devices The antenna itself Galactic noise is high below 1000 MHz. At around 150 MHz, it is approximately 1000K.
