No noise color is best for everyone: brown or pink noise often suits high-pitched tinnitus, white or pink is a reasonable start otherwise, and trying all three is a sound way to choose.
"Noise color" describes how sound energy is distributed across frequencies, and the differences aren't just marketing — white, pink, and brown noise sound different, and that difference matters for which one helps your tinnitus.
What the "colors" mean
White noise has equal energy at every frequency — mathematically the simplest of the three, and the reason it sounds the brightest and hissiest of the group, similar to television static or a radio between stations.
Pink noise reduces energy at higher frequencies relative to white noise, so more of its energy sits in the lower and middle range. It sounds noticeably softer and less harsh than white noise, closer to steady rainfall or wind.
Brown noise (sometimes called red noise) reduces high frequencies even further than pink noise, concentrating most of its energy in the low end. It sounds deep and rumbling — closer to a distant waterfall, ocean surf, or a low mechanical hum than anything hissy.
Which one to try first
There's no single correct answer — this comes down to your specific tinnitus pitch and personal preference, which is why it makes sense to try all three rather than treat one as the default. A few practical starting points:
- If your tinnitus is high-pitched (a common pattern, especially with noise-induced or age-related hearing loss), brown or pink noise is often preferred, since white noise's bright, hissy character can sit close to the same frequency range as the tinnitus itself and feel harsh rather than soothing alongside it.
- If your tinnitus is lower-pitched or you're not sure, white or pink noise is a reasonable starting point, since it covers a broader frequency range.
- For sleep specifically, brown noise is a common favorite — its low, rumbling character tends to feel less mentally stimulating than brighter noise, which matters at bedtime. Sleeping with tinnitus covers the rest of a night-time routine.
- For daytime focus or masking in a busy environment, pink or white noise often cuts through ambient background sound more effectively than brown noise's lower frequencies.
Why matching pitch isn't an exact science
In principle, sound therapy works best when the background sound has energy near your tinnitus's own pitch, which is part of the reasoning behind notched sound therapy — a more precisely tuned approach than simply picking a noise color, and available as a free pitch-matching tool on this site if you want to try it. In practice, most people don't know their exact tinnitus pitch without a formal pitch-matching test at an audiology appointment, which is why trying each of the three colors directly and noticing which one feels most soothing is a completely reasonable, evidence-consistent way to choose without needing that test first.
It's fine to switch, and fine to prefer more than one
Plenty of people use different noise colors in different situations — brown noise at night, pink noise while working, white noise while traveling. There's no evidence that switching between them reduces effectiveness or that you need to commit to one permanently. If a color that used to help stops feeling as effective, trying a different one is a reasonable, low-cost thing to do before assuming sound therapy generally isn't working for you.
What the sleep research says about pink noise
Even the sleep-specific claims for these noise colors are less settled than the marketing around them suggests. Pink noise in particular has been promoted heavily as a sleep aid based on earlier small studies, and two small 2026 laboratory studies point in different directions.
- In a pilot of 12 healthy adults, continuous pink noise played through the night reduced the brief sleep disruptions caused by road, rail and air traffic noise.
- In a study of 25 healthy adults funded by the US Federal Aviation Administration, pink noise on its own reduced REM sleep compared with a quiet night. Adding it to intermittent environmental noise slightly reduced noise-induced disruptions but worsened overall sleep structure, and foam earplugs protected sleep better than pink noise did.
Neither study involved people with tinnitus, and the larger one recruited people who did not normally sleep with background sound and followed them for only a week, so neither answers the question for someone who uses sound because silence makes their tinnitus louder. What they do show is that the evidence is mixed and context-dependent, not settled in either direction — a reason to trust your own experience over a specific color's marketed reputation if what you notice personally doesn't match the hype.
Beyond the three main colors
Nature sounds, campfire crackle, fan hum, and similar textures are, acoustically, generally variations built from these same underlying noise principles (filtered and shaped noise, sometimes layered with rhythmic elements) rather than something fundamentally different. If none of the three core colors feels right, one of these more textured options is worth trying before concluding that background sound generally isn't for you.
Getting started
This site's sound library generates all three noise colors live in your browser, along with a range of other textures, free and with no download or account required — a practical way to compare white, pink, and brown noise directly against your own tinnitus before deciding which one to build into a nightly or daily routine.
