What is pink noise?
Pink noise has equal energy in every octave, so it sounds softer and deeper than white noise. In one study (Zhou et al., 2012), sleepers exposed to steady pink noise spent more of the night in stable sleep than on quiet nights. Related research on sound and deep sleep (Ngo et al., 2013; Papalambros et al., 2017) used short bursts of pink noise timed to slow brain waves, which is a different method from this steady sound. The evidence is early and the studies are small.
Proposed mechanism
A steady broadband sound masks sudden changes in room noise, which are what tend to wake people. The timed-burst studies listed are related research, not tests of this steady sound.
What early studies describe
Early studies on pink noise describe the effects below. They are small and still being repeated, results vary from person to person, and none of this is a medical claim.
Who is this for?
People often choose pink noise for:
Experience it yourself
Reading about a frequency is one thing. Feeling it is another.
Start 60-Minute SessionThe science behind pink noise
Brainwave entrainment is the idea that the brain’s electrical activity can fall into step with a steady rhythm you hear. A related response, the Frequency Following Response (FFR), can be measured with EEG.
For pink noise there are sound-specific studies, listed below. They are early and mostly small, so read them as a reason to try it, not as proof that it will work for you.

How to use Pink Noise · Deep Sleep
Suggested session
30-60 minutes at bedtime, or all night at a low volume. Individual experiences may vary
🎧
Use headphones
Over-ear or in-ear, at a low volume. They keep the tone clear without turning it up.
🧘
Find a quiet space
A calm room makes it easier to settle in and notice how you feel.
📅
Be consistent
A short session every day is easier to keep. Notice how you feel and adjust.
Safety information
Listening to frequencies is generally considered safe for most adults. However, certain conditions require caution. Consult a healthcare professional before use if any of the following apply:
- ⚠If you are pregnant, use an implanted device, or a clinician is already caring for you, talk with them before listening
- ⚠Stop if you feel dizzy or distressed
- ⚠This is a wellness tool, not a medical device

When Science Listens to Sound
Dr. Tamara Goldsby
Researcher, Department of Family Medicine · University of California San Diego
Study summaryAn observational study of a single singing-bowl meditation session, without a control group.
In 2017, Tamara Goldsby and colleagues at UC San Diego asked 62 adults to rate how they felt before and after a one-hour sound meditation with singing bowls, gongs and bells.
After the session, participants reported feeling less tense and more at ease on standard mood questionnaires.
The study had no control group, so it cannot say how much of the change came from the sound itself rather than resting quietly for an hour.
We share it as an honest picture of where sound-meditation research is: promising, early, and worth trying for yourself.
