For the general populace, white noise typically refers to any continuous, unobtrusive background noise. However, in the realm of audio engineering, white noise represents a distinct “color” among various fuzzy-sounding noises:
- White noise: encompasses the entire audible frequency spectrum with equal intensities. It resembles the hiss encountered when a radio fails to receive a signal. Its graphical representation, with intensity on the Y axis and frequency on the X axis displayed linearly, appears as a straight, horizontal line.
- Pink noise: exhibits greater intensity in the lower-frequency range, resulting in a deeper sound akin to rainfall. Its graphical representation displays a downward slope.
- Brown noise: features even more intensity in the lower-frequency range, producing a deeper rumble resembling a distant waterfall. Its graphical representation has a steeper downward slope compared to pink noise.
- Blue noise: conversely, is characterized by a very bright sound profile, opposite to brown noise, with increased intensity in the higher-frequency range and a higher pitch than white noise. Its graphical representation resembles an upward slope.
The term “white noise machine” is somewhat inaccurate, given that these devices typically offer a variety of sounds. For example, our top recommendation, the LectroFan EVO, includes shades of pink and brown noises in addition to white noise. Similarly, our secondary recommendation, the Dohm, produces a range of fan sounds that, depending on the setting, can resemble brown noise to some extent. Rafael Pelayo, the author of “How to Sleep,” suggests that a more suitable term for these devices would be “sound generators.”

Top-Rated White Noise Machine, Scored 10/10
Pros:
- Sleek design suitable for minimalist bedrooms and nurseries alike.
- Versatile aesthetic appeal.
- Intuitive operation.
Cons:
- The comprehensive app may appear daunting to some users.
The Momcozy white noise machine boasts subtle elegance when powered off and becomes vibrant and visually appealing when illuminated, adding a touch of joy to any space.

Personalizing your sleep routine is simple with options like scheduling gentle wake-ups and selecting soothing sounds such as blue-hued rainfall, which helps distract from tinnitus.
Featuring three fan noises—floor, wall, and regular—the Momcozy offers versatility in sound selection, though the differences between them may not be stark. A noteworthy feature allows users to lock the controls remotely via smartphone, preventing accidental adjustments, particularly handy to maintain a peaceful ambiance.

Lumi White Noise Machine
Top Value White Noise Machine, Rated 9/10
Pros:
- Impressive battery life, offering up to 20 hours of continuous use.
Cons:
- Lack of a child lock feature.
- Presence of multiple buttons may be prone to accidental presses by curious hands.
This white noise machine resembles a reliable car—functional yet lacking in style. Its chunky grey interface is filled with buttons, offering extensive control akin to what an app would provide, albeit without the luxury of having one. Despite the cluttered appearance, when you’re enjoying its colorful glow or simply with your eyes closed, aesthetics become secondary.
Constructed from somewhat hollow and inexpensive-feeling plastic, it might raise concerns about durability, especially around children who might mishandle it. Furthermore, the absence of a child lock feature suggests it’s more suited for placement on a shelf, away from curious little hands.
However, despite its shortcomings, the device delivers on its promises, offering high-quality white noise alongside a variety of other soothing sounds. The convenience of remembering preferred settings, such as the bonfire sound, adds to its appeal and makes it a dependable choice for creating a tranquil environment.
Hatch Restore 2
Top-Rated White Noise Machine for Sleeping, Rated 9/10
Pros:
- Comprehensive emphasis on sleep and overall well-being.
Cons:
- Some content is inaccessible without additional payment, which may be off-putting given the initial investment.
Describing the Hatch Restore 2 as a mere white noise machine would be akin to labeling a Bugatti Veyron as a simple run-around car. While other devices offer assistance at bedtime or naptime, the Hatch transcends this role to become more of a bedside sleep therapist, offering a plethora of features and considerations.
However, one drawback is that a significant portion of its functionality is accessible only through a subscription service costing £43 per year. The accompanying app frequently encourages users to subscribe, tantalizing them with enticing offerings such as meditation sessions, sleep stories, and ‘dreamscapes’ featuring field recordings from around the world. For those yearning to experience Icelandic waterfalls or the California coast, £43 may seem a bargain compared to the cost of a flight.
Nevertheless, the free features are undeniably impressive. From the biscuity-toned fabric minimalist clock that transforms with a swipe of the finger on the color wheel to the sunrise alarm clocks gently coaxing users into the new day, every aspect of the Hatch exudes sophistication and luxury. The device’s touch-sensitive interface, coupled with the app’s kind and encouraging nature, contributes to its overall appeal.
Despite its steep price tag, the Hatch Restore 2 delivers a premium experience, making it a worthwhile investment for those seeking a sophisticated and comprehensive sleep solution.
