What pink noise is

Pink noise decreases in intensity by about 3 dB per octave — equal energy per octave band. It sounds warmer than white noise and matches how many natural systems distribute energy.

Studio and sleep applications

Sound engineers play pink noise through monitors to tune room EQ. For sleep, pink noise sits between white and brown — less harsh than white, less boomy than brown on small speakers.
