A practical listening guide
White Noise for sleeping
White noise spreads power evenly across audible frequencies. It has a bright, steady character that many people use to make changing background sounds less noticeable.
What it sounds like
It sounds like a clean, continuous hiss—the acoustic equivalent of a blank, even surface. This generator creates fresh samples continuously, so there is no short recording loop to notice overnight.
How people use it
People commonly use white noise to mask speech, household activity, and inconsistent office sound. For sleep, keep the output comfortable and low; browser volume percentages are not physical decibel measurements.
How it differs
White noise carries more high-frequency energy than pink or brown noise. If it feels sharp, try the Warmer tune control or switch to pink noise for a gentler balance.
How this player generates it
The generator targets broadly flat power spectral density. The live analyzer displays the app’s outgoing digital signal in dBFS and does not listen through your microphone.
