Brown Noise 10 Hours - For Study, Relaxation and Sleep

Brown noise, also known as "red noise" or "random walk noise," is a type of noise that is characterized by a power spectral density (PSD) with a negative slope of 6 decibels per octave. It has a lower frequency content compared to white noise and a more "rough" or "buzzing" sound. The name "brown noise" comes from the fact that it is thought to resemble the sound of Brownian motion, which is the random movement of particles in a fluid.
