Brown Noise (10 Hours) Sleep Sound

Brown noise, also known as Brownian noise or red noise, is a type of random signal that falls within the realm of sound and acoustics. It is named after the botanist Robert Brown, who first observed the phenomenon of random motion in particles suspended in a fluid. Brown noise is characterized by its power spectral density, which means it has equal energy per octave or equal energy per logarithmic frequency interval.

Regarding auditory perception, brown noise is a deep, low-frequency sound like the rumble of thunder. It has a consistent energy distribution across the entire audible frequency range, with higher intensity at lower frequencies. Brown noise contains all audible frequencies with equal power, but its intensity decreases as the frequency increases.

The benefits of brown noise lie in its potential effects on human physiology  ...
