Black Noise (theory)

Black noise is a type of complex, unpredictable signal characterized by a lack of dominant frequencies, making it distinct from white or pink noise. Unlike white noise, which contains all frequencies at equal intensity, black noise has energy concentrated in very low or very high frequencies, often appearing as near silence or deep background chaos. Its unpredictability and spectral structure make black noise useful in areas like signal processing and modeling phenomena with high variability. Essentially, black noise represents a form of randomness with specific spectral features, highlighting the complexity of certain natural and artificial systems.
