2. White noise - Wikipedia

   en.wikipedia.org/wiki/White_noise

   The waveform of a Gaussian white noise signal plotted on a graph. In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density. [1]

   Sound machines are a popular solution to this age-old problem…but is white noise safe for babies? Here’s everything you need to know, according to a pediatrician and sleep coach. Meet the ...

4. Colors of noise - Wikipedia

   en.wikipedia.org/wiki/Colors_of_noise

   It is also known as differentiated white noise, due to its being the result of the differentiation of a white noise signal. Due to the diminished sensitivity of the human ear to high-frequency hiss and the ease with which white noise can be electronically differentiated (high-pass filtered at first order), many early adaptations of dither to ...

5. Gaussian noise - Wikipedia

   en.wikipedia.org/wiki/Gaussian_noise

   In signal processing theory, Gaussian noise, named after Carl Friedrich Gauss, is a kind of signal noise that has a probability density function (pdf) equal to that of the normal distribution (which is also known as the Gaussian distribution). [1] [2] In other words, the values that the noise can take are Gaussian-distributed.

   The big three in sleep sounds are white noise, brown noise, and pink noise, but there are many other noise types, including purple noise, gray noise, and even black noise (a.k.a. good ol ...

8. Noise (signal processing) - Wikipedia

   en.wikipedia.org/wiki/Noise_(signal_processing)

   White noise. Additive white Gaussian noise; Black noise; Gaussian noise; Pink noise or flicker noise, with 1/f power spectrum; Brownian noise, with 1/f 2 power spectrum; Contaminated Gaussian noise, whose PDF is a linear mixture of Gaussian PDFs; Power-law noise; Cauchy noise; Multiplicative noise, multiplies or modulates the intended signal

9. Noise (spectral phenomenon) - Wikipedia

   en.wikipedia.org/wiki/Noise_(spectral_phenomenon)

   White noise, which has constant power spectral density; Gaussian noise, with a probability density function equal to that of the normal distribution; Pink noise, with spectral density inversely proportional to frequency; Brownian noise or "brown" noise, with spectral density inversely proportional to the square of frequency
