Key Terminology & Definitions
Pink Noise ($1/f$)
A signal with equal energy per octave, mirroring human psychoacoustic frequency perception across the audible spectrum.
Brownian / Red Noise ($1/f^2$)
A deep acoustic noise with power density decreasing by 6 dB per octave, resembling the soothing roar of heavy rain or distant waterfalls.
