White and red noise have unique features and uses. We’ll delve into their differences, benefits, and uses, especially how they impact sleep.
Let’s get started.

Red noise has a deeper, resonant hiss due to its emphasis on lower frequencies.
-
White noise improves sleep quality, enhances focus, and offers potential relief for tinnitus sufferers.

What Is White Noise?
Put simply, white noise is a blend of all frequencies played at the same intensity that are audible to human ears. It produces a uniform, static-like sound that can efficiently cover other surrounding noises.
Here are examples of white noise:
-
TV static
-
A running vacuum cleaner
-
The hum of an air conditioner
-
A whirring electric fan
(White noise can also be generated artificially.)
According to Soundly, “The consistent and unchanging nature of white noise can create a privacy screen, helping to establish a quieter, more serene environment conducive to focus, relaxation, or sleep.(1)”
What Is Red Noise?
Red noise is dominant in terms of lower frequencies compared to higher ones. While it sounds like a hiss, it has a deeper, more resonant tone. Unpredictable fluctuations in electrical currents supposedly generate it.
Naturally occurring examples of red noise include:
-
Rumble of far-off thunder
-
Crashing of ocean waves
Better Sleep states, "It is a type of ambient noise generated by electronic devices and is often used for testing purposes in fields such as acoustics and telecommunications.(2)”
White Noise vs Red Noise: How Do They Differ?
Knowing how they differ is essential to understanding white and red noise better. Here is a table outlining their differences:

What Are the Pros of White Noise?
There are several white noise benefits. Here are a couple:
The continuous, uniform hiss of white noise may improve sleep quality. How? It masks intrusive sounds, preventing you from drifting off or staying asleep. Good sleep quality means falling asleep in up to 30 minutes. Also, waking up more than once can harm the quality of your zzzs.
White noise’s unchanging sound can effectively mask disruptive background sounds in the workplace. This quality allows you to focus better, leading to increased productivity. According to Soundly, some studies indicate that “white noise can enhance productivity, making it easier to tune out other noise in the office and an excellent tool for workplaces and study spaces.(3)”
Experts often recommend white noise for tinnitus relief. In case you’re unfamiliar with tinnitus, it's a ringing or buzzing in the ears that only you can hear. Mayo Clinic states that white noise machines “produce a sound similar to static, or environmental sounds such as falling rain or ocean waves, are often an effective treatment for tinnitus.(4)”
What Are the Advantages of Red Noise?
Now let’s move on to red noise, which also offers its own set of benefits.
First, red noise is known for its deep and rumbling sound, which can be more soothing for some than white noise. This natural sound quality may be effective when getting some R&R. For example, white and red noise mask disruptive sounds. The table above shows that it's better at covering up low-frequency sounds.
Some studies suggest that the frequencies in red noise can trigger relaxation and help ease stress and anxiety. Red noise while working or studying can reduce stress, improving overall well-being and work quality. And that’s not all. Some research shows that it can boost your creativity and mental sharpness.
Regarding better sleep quality, red noise works like white noise. However, many prefer red noise’s deeper rumble over the harshness of white noise. It’s all about preference.
Also, according to Better Sleep: “Red noise has numerous benefits for improving sleep, concentration, and overall well-being. It can also be used in therapy for those with sensory processing disorders or tinnitus.(5)”
Which One Is Best for You — White Noise or Red Noise?
Now, on to the big question: What is better for you — white or red noise? We’ve already outlined each one’s benefits, so it boils down to what sound is more appealing to you and the type of noise you want to drown out.
White noise may be your best if you’re dealing with high-frequency sounds like your neighbor’s barking dog or construction noises. Meanwhile, the opposite holds for red noise, which is more effective for low-frequency sounds.
Remember that white noise is static-like and may sound harsher than rumbling red noise for some. Experiment with each to determine which noise color works better for you, whether you’re using it to boost sleep or improve your focus.
Also, consider your goal. White and red noise have similarities but also unique benefits we mentioned above. For example, say you expect to be extra busy at work the next day. So, you must ensure you’re at the top of your game. Red noise might be the better option because it supposedly boosts creativity and mental acuity.
For instance, you suffer from tinnitus. Is the annoying ringing in your ears getting unbearable? If you answered yes, then try listening to white noise. Of course, clear it with your healthcare provider first.
