White Noise vs. Pink Noise vs. Brown Noise for Tinnitus

"Noise color" describes how sound energy is distributed across frequencies, and the differences aren't just marketing — white, pink, and brown noise genuinely sound different, and that difference matters for which one actually helps your tinnitus.

What the "colors" actually 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 actually try first

There's no single correct answer — this genuinely comes down to your specific tinnitus pitch and personal preference, which is exactly why this site's sound library includes all three rather than picking 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.
• 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 (covered in the sound therapy article) — 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.

Worth being honest about: even the sleep-specific claims for these noise colors are less settled than marketing around them suggests. Pink noise in particular has been promoted heavily as a sleep aid based on earlier small studies, but more recent research (including a study sponsored by the US Federal Aviation Administration examining pink noise against intermittent aircraft noise) found it could actually disrupt sleep quality in some conditions rather than improve it. This doesn't mean pink noise is bad for sleep — the evidence is genuinely mixed and context-dependent, not settled in either direction — but it's 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 — also available in this site's sound library — 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.
