What is brown noise?

Brown noise is a deep, low-frequency sound. It’s smoother and softer than white noise, more like distant thunder or a waterfall. No harsh highs. No sharp hiss.

 

Making high-pitched sounds feel less intense

Many autistic people are especially sensitive to sharp or high-frequency noises. Brown noise fills the space with a deep, steady sound which makes high-pitched sounds stand out less, so they feel softer and less sharp—making them easier to tolerate.

 

Masking unpredictable background sounds

Unpredictable noises (e.g., voices, doors, traffic, appliances, etc.) can be distressing. Brown noise creates a steady, continuous sound that helps mask sudden changes in the environment and creates a sense of predictability, which can be especially calming for autistic people.

 

Less distractions

Brown noise can improve focus by reducing sensory ‘competition’. It can help the brain filter distractions during studying, working, or sleeping. Some people find it easier to concentrate when it plays quietly in the background.

 

Emotional regulation

Certain sounds, lights, or touch can feel overwhelming for many autistic people. Low-frequency sounds can have a calming, grounding effect. Similar to deep pressure or weighted blankets, brown noise can feel physically stabilizing.

 

Important reminder

Not every autistic person likes brown noise: what helps one person may bother another. Volume matters: too loud can cause the opposite effect. If it feels irritating, heavy, or overwhelming, just stop—the same way you would with any other sound or music. This tool isn’t for everyone, but for many it can be a simple, free way to create a safer sensory space. ♡

 

When it’s often helpful

Just a few examples:

•  Falling asleep

•  Sensory overload

•  Anxiety

•  Meltdown & shutdown recovery

•  Focus, study, or cozy hobbies

Some sensory-sensitive people prefer it over silence.

Besides my new, 10-hour brown noise (black screen) video, I also share autism-friendly ambiences with gentle hand-drawn animations & calming sounds. Perfect for sleep, focus, or calm. 

How to try brown noise

Start at very low volume. Use it during one activity (e.g., sleep, rest, or focus). Let it fade into the background. It should feel neutral or calming, not intense. If it increases irritation, stop.
