Brown noise, also known as red noise or Brownian noise, is a type of random noise that has a spectral density inversely proportional to the frequency squared. It is often described as a low-frequency noise that resembles the sound of a waterfall or rushing air. Brown noise has a deeper, rumbling quality and is often used for relaxation, as a sleep aid, or to mask other sounds. White noise, on the other hand, is a type of noise that contains equal energy across all frequencies. It is characterized by a constant and uniform distribution of sound energy, resulting in a hissing or static-like sound. White noise is often referred to as "pure" noise and is commonly used for sound masking, concentration, or creating a neutral background sound. When combining brown noise and white noise, the resulting sound would likely have a wider frequency range compared to pure brown or white noise alone. It would have a low-frequency rumble and depth of brown noise, providing a soothing and relaxing quality. At the same time, the white noise component would add a hissing or static-like texture, contributing to more evenly distributed sound energy across frequencies. I think this brown and white noise mix creates a unique auditory experience that offers both the calming qualities of brown noise and the neutral, uniform sound of white noise.
