What Is Pink Noise?
Pink noise has equal energy in each octave, so its power falls by 3 dB per octave. It sounds warmer and less harsh than white noise, similar to steady rain. See the pink noise article.
Benefits
People use it for sleep, concentration and relaxation. Audio engineers also use pink noise to test speakers and room acoustics because it resembles real music energy.
Tips for Best Use
Play at low volume, place the speaker a few meters away and try a sleep timer on your phone. Switch to white noise if you need stronger masking.
Use Pink Noise to Test Speakers
Play it and listen for tonal imbalances, rattles and uneven coverage. Combine with the frequency generator.
