Random Noise or Intelligence? We Filter Internet VLF signals LIVE
In this demonstration we ask the question: Could it be possible that there are voices of people in the energy all around us? How much do we really know about the world around us? Will you just listen to what we are told and assume that is all there is? Or will you think outside the box and say "what if?" Discoveries are made by those who question possibilities and discover new ones. In this LIVE Facebook stream on 6/14/17 we take a look at the live VLF stations available on the website: http://abelian.org/vlf/ We stream a station from Cape Coral, Florida and filter it. We also use a creative augmentation technique. After some experimenting we switch to a stream from Italy at request of someone on Facebook. We then filter it and find out that there is something that appears to be voice.... but it shouldn't exist.... If you listen to the world of science they will tell you what is or isn't. Is there voice in the energy all around us? You decide. Presented by Keith J. Clark of iDigitalMedium

Random Processes - 04 - Mean and Autocorrelation Function Example
http://adampanagos.org The previous videos provided definitions of the mean and autocorrelation function of a random process. In this video we work with the random process X(t) = Asin(wc*t + theta) where both A and theta are random variables. We compute the mean function and autocorrelation function of this random process. We show that the mean function is zero, and the autocorrelation function is just a function of the time difference t1-t2. Thus, this random process is a wide-sense stationary (WSS) random process (which we'll formally define late).

Random Radar or Calculated Composition? Unexplained Radio Signals for June 2016
For 10 years I''ve been working with radio - specifically with the hope that non-physical people (ie. people in spirit, the afterlife, etc.) will be able to work with me and eventually..have a full conversation. We've had some success...it's a lot of work. It requires a lot of patience...and a lot of time. Sometimes strange things happen. This month's recording of as-yet-unexplained audio tones on a radio receiver tuned to 25.5Mhz in Clearwater Florida - seeks to look a little further into this phenomena. Are these audio tones just random radar signals - or is there something more? Is there a natural order in radar signals that sounds like classical music? Or could there be intelligent beings using low frequency radio waves to communicate? You Decide.

What Is White Noise?
Jonathan defines what white noise actually is and how it's used to mask other annoying sounds. Learn more at HowStuffWorks.com: http://science.howstuffworks.com/question47.htm Share on Facebook: http://goo.gl/n7YNrZ Share on Twitter: http://goo.gl/Fq9InS Subscribe: http://goo.gl/ZYI7Gt Visit our site: http://www.brainstuffshow.com Cross over into BrainStuff now children. All are welcome! But… before we go into the light together, there seems to be some confusion among you about what “white noise” is. No, it isn’t when you have that snowy static on your TV and ghosts fly out of the screen and your daughter says, “They’re here!” White noise is something we’ve all heard, some of us without even knowing it. So let’s define what it is exactly, how it’s used to mask other sounds and what other “colors” exist on the spectrum of sound. The simplest definition is that white noise is the noise produced by combining all the different frequencies of sound together at once. Each of these frequencies is projected at an equal amount, from low to high. Because white noise has an equal energy distribution, sound technicians refer to its frequency spectrum as being completely flat. Some machines -- like fans for instance -- can create an approximation of white noise by hitting all these notes. That’s why they’re so good at creating background noise that masks other sounds. When there are sudden changes in noise, we’re often distracted by the jarring clash. Especially if we’re sleeping. White noise’s masking effect blocks out those changes, making it easier to sleep through the night. That’s one reason some people leave a fan, air purifier or a television on in the middle of the night. This sound masking is also used to block noise in places like offices, hotels and libraries, often broadcast over a PA system. If you’re trying to concentrate in a disturbing environment and there aren’t filters like these in place, you can always listen to white noise on your headphones to mediate the conflicting sounds around you. How do you think we write these BrainStuff episodes when we all live together in this tiny studio prison and are never allowed to leave? There is peace and serenity in the white noise. We call it “white” noise because it’s analogous to how white light works, being made up of all the different frequencies of light. But white noise isn’t the only “color” on the sound spectrum. Depending on the way signals are distributed over different frequencies they can be red, blue, violet or gray. Pink noise for example is very similar to white noise, but its higher frequencies have less intensity, making it louder and more powerful on the low end. This makes it useful for testing speakers and amplifiers. Like white noise, it’s also used to mask background sounds. And pink noise even occurs naturally in heartbeat rhythms, meteorological data and the radiation output of astronomical bodies.

white noise White noise From Wikipedia, the free encyclopedia For other uses, see White noise (disambiguation). Plot of a Gaussian white noise signal. In signal processing, white noise is a random signal with a flat (constant) power spectral density. In other words, a signal that contains equal power within any frequency band with a fixed width. The term is used, with this or similar meanings, in many scientific and technical disciplines, including physics, acoustic engineering, telecommunications, statistical forecasting, and many more. (Rigorously speaking, "white noise" refers to a statistical model for signals and signal sources, rather than to any specific signal.) A "white noise" image. The term is also used for a discrete signal whose samples are regarded as a sequence of serially uncorrelated random variables with zero mean and finite variance. Depending on the context, one may also require that the samples be independent and have the same probability distribution. In particular, if each sample has a normal distribution with zero mean, the signal is said to be Gaussian white noise.[1] Il rumore bianco è un particolare tipo di rumore caratterizzato dall'assenza di periodicità nel tempo e da ampiezza costante su tutto lo spettro di frequenze. È chiamato bianco per analogia con il fatto che una radiazione elettromagnetica di simile spettro all'interno delle banda della luce visibile apparirebbe all'occhio umano come luce bianca. Nella pratica però il rumore bianco non esiste: si tratta di un'idealizzazione teorica, poiché nessun sistema è in grado di generare uno spettro uniforme per tutte le frequenze esteso da zero a infinito, mentre nei casi reali d'interesse il rumore bianco è al più riferibile ad un intervallo di frequenze (rumore bianco a banda finita o limitata). Si presenta così spesso uno spettro con caratteristiche simili al rumore bianco, ma con ampiezza maggiore alle basse frequenze e minore fino ad azzerarsi alle frequenze maggiori.

Pink Noise - Ten Hours - Ambient Sound - Blocker - Masker - Burn In - Relaxation -The Best
Ten hours of uninterrupted pink noise. 4K-HD version https://youtu.be/OS931VC09Ww. Buy noise clips here https://electriccanyon.com/product/pink-noise-10-hours/ $1.50 Support channel creations here https://www.patreon.com/dalesnale https://PayPal.Me/dalesnale Thanks For relaxation at low level and masking of other noise in your direct environment. Pink noise randomized static which sounds like a combination of the ocean and a TV set. Television static is white noise by definition which is thinner sounding with less low frequencies than pink noise. Also referred to as Flicker Noise, Pink Noise has equal energy to all sound frequency octaves. That means more lows, or bass frequencies, that sound similar to the power of the natural ocean waves or a large waterfall. Immerse yourself in pink noise for a whole day shift or a good night's sleep. Experience the effects of Pink noise over time to understand what it is and its potential natural calming effect on the mind. Noise, even at a low level, seems to have the effect of masking more disruptive sounds in the listening environment. It has been used in offices to subdue the mechanical sounds of office equipment voices and phones. Pink Noise is electronically generated, yet seems to have a primal aesthetic. Perhaps it is similar to what a baby hears before birth. Moms use this for baby crying relief regularly.It is absolutely reminiscent of natural sounds: the ocean, a large waterfall, heavy rain and wind...all of which man has listened to since the dawn of time. Listeners use pink noise for meditation, is it masking or soothing or calling to a primal past? Perhaps all of the above. So many uses, I had not conceived. Thanks listeners! I do know that... Pink Noise is used by Audio Engineers to test speakers as the full spectrum sound can quickly reveal optimal speaker performance or speaker issues. Mixing consoles and audio software programs often have pink and white noise built in for testing signal through various signal paths of a board through the amplifiers and to the speakers. This brings us to headphone burn in. I have to admit, headphone burning was not on my mind when I made the Ten Hours of Pink Noise. I had heard of the concept. I figured audio engineers would find the clip useful as a playback through PA and recording gear not equipped with a signal generator. It wasn't long before the burn in comments started coming in. I have never deliberately set out to break my headphone in, but many do. A few manufacturers mention the technique. Headphones are meant to be used out of the box, There are listening enthusiasts who feel a worn in set of headphones sound better. By playing full spectrum pink noise for an extended period,..the burn in procedure is theoretically more even than playing back music. Check out the comment field and it's plain to see there are believers and non-believers of headphone burn in. I say, what can it hurt? Burn away. And thanks listeners for sharing headphone models and brands and listening observations. I'm going to listen to the commenters before my next high-end headphone purchase. On a technical note: The amount of spectrum energy decreases 10 dB/octave of frequency. This creates increased low frequency information in relation to mid-range and high frequencies. This is the first ever long play noise on DaleSnale channel and I thank YouTube for the 'Official' ranking. It's rough around the edges and preceding videos have improved in graphic quality as we move into the HD era. All the audio is generated and mixed at ElectricCanyon recording studio to ensure a pleasant listening or burning experience. There are several noise colors to choose from. Try them all or mix and match a recipe playing back more than one in multiple browser tabs. Happy Listening. Dale #pinknoise #tenhournoise #dalesnale

TV Static White Noise 10 Hours | Sleep, Study, Focus, Work, Mask Tinnitus, Soothe Crying Baby
Buy TV Static MP3: https://goo.gl/B0FlrQ Remember that nice feeling of falling asleep to the sound of static on TV? Digital TVs often go to black or otherwise eliminate the static, so here is some analog white noise goodness. By the way, for you purists out there, this is true white noise. Many of my other videos are white noise variations, but this is the real deal :) Use this sound for sleeping, studying, masking tinnitus and blocking out distracting noises. It is also great for soothing a colicky infant or putting your baby to sleep. In fun trivia, the Indonesian word for white noise translates to "war of the ants." The Hungarian word for white noise translates to "ant soccer". Here's the rest of the Wikipedia entry that mentions those tidbits: From Wikipedia, the free encyclopedia http://creativecommons.org/licenses/by-sa/3.0/ Noise, in analog video and television, is a random dot pixel pattern of static displayed when no transmission signal is obtained by the antenna receiver of television sets and other display devices. The random pattern superimposed on the picture, visible as a random flicker of "dots" or "snow", is the result of electronic noise and radiated electromagnetic noise accidentally picked up by the antenna. This effect is most commonly seen with analog TV sets or blank VHS tapes. There are many sources of electromagnetic noise which cause the characteristic display patterns of static. Atmospheric sources of noise are the most ubiquitous, and include electromagnetic signals prompted by cosmic microwave background radiation,[1] or more localized radio wave noise from nearby electronic devices.[2] The display device itself is also a source of noise, due in part to thermal noise produced by the inner electronics. Most of this noise comes from the first transistor the antenna is attached to.[2] Due to the algorithmic functioning of a digital television set's electronic circuitry and the inherent quantization of its screen, the "snow" seen on digital TV is less random. UK viewers used to see "snow" on black after sign-off, instead of "bugs" on white, a purely technical artifact due to old 405-line British receivers using positive rather than the negative video modulation used in Canada, the U.S., and (currently) the UK as well. Most modern televisions automatically change to a blue screen or turn to standby after some time if static is present. Since one impression of the "snow" is of fast-flickering black bugs on a white background, in Sweden, Denmark and Hungary the phenomenon is often called myrornas krig in Swedish, myrekrig in Danish, hangyák háborúja in Hungarian, and semut bertengkar in Indonesian, which translate to "war of the ants" or sometimes hangyafoci in Hungarian which means "ant soccer", and in Romanian, purici, which translates into "fleas".

Traffic Noise in India
Filmed in Bangalore on Tumkur Road which leads out of Bangalore towards Bombay - described by my rickshaw driver as 'Bombay Road' Traffic noise can cause serious and permanent hearing damage, interfere with communication, disturb sleep, cause cardiovascular and psycho-physiological effects and provoke annoyance responses and other changes in social behaviour. Noise can adversely affect performance, attentiveness, problem solving and memory. Impaired performance leads to a higher risk of accidents. Prolonged or excessive exposure to noise, whether in the community or at work, can cause permanent medical conditions, such as hypertension, ischaemic heart disease and inner ear damage causing deafness. "Hearing impairment can impose a heavy social and economic burden on individuals, families, communities and countries. Hearing impairment in children may delay development of language and cognitive skills, which may hinder progress in school. In adults, hearing impairment often makes it difficult to obtain, perform, and keep jobs. Hearing impaired children and adults are often stigmatized and socially isolated." http://www.who.int/mediacentre/factsheets/fs300/en/ Noise above 80 dB can increase aggressive behaviour. There is a link between community noise and mental health problems, suggested by a high demand for tranquillizers and sleeping pills,higher incidences of psychiatric symptoms and the number of admissions to mental hospitals.

Application of Registers, Random Signal ...
Application of Registers, Random Signal Sequence Generator Random sequences of signals and codes are widely used in testing equipment, noise generators, and logical game devices. It is possible to build a random signal sequence generator on a shift register. Strictly speaking, the sequence will not be completely random, but Quasi-random, that is they will be periodically repeated but this period is quite large. The objective is to make the output signal or code change its state randomly (or almost randomly). The signal must randomly switch from 0 to 1 and from 1 to 0, and the code must randomly take values ​​between 0 and 2 raised to the power of (N-1), where N is the number of bits in the code. The structure of quasi-random sequence generator at the shift register is quite simple. It is a shift register with parallel outputs. Several of its output signals are combined by the Exclusive OR gate, whose output a signal is sent to the input of the register closing the circuit in a ring. The scheme is clocked by a signal with frequency f. It is difficult to choose bit numbers to connect the feedback, but there are reference tables, in which they are represented. In any case, one of the points of connection is a higher-level output. The period of the output sequence of a generator is 2 raised to the power of N minus 1 cycle, where N is the number of bits of the shift register. During this time, each of the possible values ​​of the output code (except one) occurs once. The number of units in the output signal exceeds the number of zeros by one. A zero output code is a forbidden state, since it blocks the operation of the generator, reproducing itself over and over again. At the same time such a zero code can only create itself from itself, so it is enough to ensure that it is absent when powering the circuit. For example, let's consider the circuit of a pseudorandom sequence generator on a 31-bit shift register. Feedback is received from outputs 30 and 17 of the register through a two-input Exclusive OR component with an inverter. Due to the use of prohibited state inverter generator there is a code consisting of only ones, which in this case can be eliminated simply with the initial reset of registers to zero at powering on reset. Generator produces quasi-random sequence of 31-bit codes on all register outputs, as well as quasi-random sequence of ones and zeros at any of the register outputs.

White Noise Sound - Help you sleep and relax - High Quality
Welcome to my White Noise sound video. In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density.[1] The term is used, with this or similar meanings, in many scientific and technical disciplines, including physics, acoustic engineering, telecommunications, statistical forecasting, and many more. White noise refers to a statistical model for signals and signal sources, rather than to any specific signal. A "white noise" image In discrete time, white noise is a discrete signal whose samples are regarded as a sequence of serially uncorrelated random variables with zero mean and finite variance; a single realization of white noise is a random shock. Depending on the context, one may also require that the samples be independent and have identical probability distribution (in other words i.i.d. is the simplest representative of the white noise). In particular, if each sample has a normal distribution with zero mean, the signal is said to be Gaussian white noise.

A signal as referred to in communication systems, signal processing, and electrical engineering is a function that "conveys information about the behavior or attributes of some phenomenon".[1] In the physical world, any quantity exhibiting variation in time or variation in space (such as an image) is potentially a signal that might provide information on the status of a physical system, or convey a message between observers, among other possibilities.[2] The IEEE Transactions on Signal Processing states that the term "signal" includes audio, video, speech, image, communication, geophysical, sonar, radar, medical and musical signals.[3] In nature, signals can take the form of any action by one organism able to be perceived by other organisms, ranging from the release of chemicals by plants to alert nearby plants of the same type of a predator, to sounds or motions made by animals to alert other animals of the presence of danger or of food. Signaling occurs in organisms all the way down to the cellular level, with cell signaling. Signaling theory, in evolutionary biology, proposes that a substantial driver for evolution is the ability for animals to communicate with each other by developing ways of signaling. In human engineering, signals are typically provided by a sensor, and often the original form of a signal is converted to another form of energy using a transducer. For example, a microphone converts an acoustic signal to a voltage waveform, and a speaker does the reverse.[1] The formal study of the information content of signals is the field of information theory. The information in a signal is usually accompanied by noise. The term noise usually means an undesirable random disturbance, but is often extended to include unwanted signals conflicting with the desired signal (such as crosstalk). The prevention of noise is covered in part under the heading of signal integrity.

White Noise  Beth Bento
In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density. The term is used, with this or similar meanings, in many scientific and technical disciplines, including physics, acoustic engineering, telecommunications, statistical forecasting, and many more. White noise refers to a statistical model for signals and signal sources, rather than to any specific signal. A "white noise" image. In discrete time, white noise is a discrete signal whose samples are regarded as a sequence of serially uncorrelated random variables with zero mean and finite variance; a single realization of white noise is a random shock. Depending on the context, one may also require that the samples be independent and have identical probability distribution (in other words i.i.d. is a simplest representative of the white noise). In particular, if each sample has a normal distribution with zero mean, the signal is said to be Gaussian white noise. Generation White noise may be generated digitally with a digital signal processor, microprocessor, or microcontroller. Generating white noise typically entails feeding an appropriate stream of random numbers to a digital-to-analog converter. The quality of the white noise will depend on the quality of the algorithm used.
