Pink Noise
Balanced, softer noise suited to relaxation, concentration and rest.
What is pink noise?
Pink noise is broadband noise whose power decreases as frequency rises — approximately 3 dB per octave in the idealized definition. Compared with white noise, this gives relatively more weight to lower frequencies and is often heard as softer or smoother.
Idealized definition: power falls by roughly 3 dB per octave as frequency rises. Not a measurement of this Quiet Hub recording.
Pink vs white vs brown noise
Pink noise sits between white and brown noise in spectral weighting: less bright than ideal white noise, but not as strongly weighted toward low frequencies as brown noise.
When might you choose pink noise?
Pink noise is a reasonable sound to test if white noise feels too bright but you still want a steady broadband background. Common uses include sleep, winding down, study and general background listening. Preference and context matter; the evidence does not establish pink noise as universally better than white or brown noise.
