What is the difference between white noise and brown noise?

Last Updated: 4th April, 2020

White noise is broadly spread across thesoundspectrum, including low-frequency, mid-range, andhigh-frequencysounds. Most people find this noise verycalming andpleasant. Brown noise is even deeper, evenstronger at thelow end, and without the high frequency sounds ofwhite andpink noises.

Consequently, is Brown noise better than white noise?

As the video explains, white noise has ahigherfrequency and we perceive it to sound louder than itreallyis. Pink noise, which they play in the video, takesthisinto account and balances out the frequency. Brownnoise,which sounds like a low rumble or an ocean, lowers thehigherfrequencies even more.

Furthermore, what does Brown noise mean? Brown noise is one of the many colorsofnoise, which also include white noise,pinknoise and blue noise. Brown noise isalsoknown as Brownian noise because its change in soundsignalfrom one moment to the next is random.

What is blue noise?

Blue noise is a noise color with aspectraldensity (power per hertz) that is proportional to itsfrequency.Because blue noise is biased toward higherfrequencies, itsounds like a high-pitched hiss completely lackinganybass.

What is white or pink noise?

Pink noise is a color of noise,notentirely unlike white noise. White noise hasequalpower per hertz throughout all frequencies, while the powerperhertz in pink noise decreases as the frequency increases.Asa result, the lower frequencies in pink noise are louderandhave more power than the higher frequencies.
