WebApr 12, 2016 · So, Pink noise is filtered white noise whose frequency spectrum decreases following a specific relationship. This means that pink noise has more low frequencies which in turn means that any two neighbouring events would have higher probabilities of occurring but that would not hold for any two events (as it was in the case of white noise). WebWhereas white noise is defined as sound with equal power per Hz in frequency, pink noise is filtered to give equal power per octave or equal power per 1/3 octave. Since the number of Hz in each successive octave increases by two, this means the power of pink noise per Hz of bandwidth decreases by a factor of two or 3 decibels per octave.
