Yogasleep Dohm vs. LectroFan EVO
Dohm is a real fan (never loops). LectroFan EVO is electronic with 22 non-looping sounds. Choose natural texture or variety.
Both are long-standing sound machine favorites, but they represent two fundamentally different approaches to masking noise. The **Yogasleep Dohm** is a mechanical device: a real fan inside an acoustic housing that generates broadband white noise by physically moving air. Because there's no audio loop, the sound is continuous and never repeats. The **LectroFan EVO** is an electronic device that generates (rather than plays back a recorded loop of) 22 sounds — 10 fan sounds, 10 white/pink/brown noise variations, and 2 ocean surf sounds — with fine-step volume control and a sleep timer. Purists who want a real fan tend to prefer the Dohm; people who want variety or more volume tend to prefer the EVO.
Category by category
| Category | Winner | Reason |
|---|---|---|
| Sound naturalness | A | A real fan moving air produces natural-sounding white noise. Electronic generation is close but not identical. |
| Loop-free guarantee | A | Dohm is mechanical — there's physically no loop. EVO uses generated audio that avoids loops but is still electronic. |
| Sound variety | B | LectroFan EVO has 22 sounds. Dohm has one sound (its fan), with tone adjusted by twisting the housing. |
| Maximum volume | B | LectroFan EVO goes louder than the Dohm, which matters for masking heavy traffic or loud neighbors. |
| Durability | A | The Dohm's simple fan-and-motor design has been sold since 1962, and owners often report many years of use. The LectroFan is a solid-state electronic device with a shorter track record. |
| Price | Tie | Both are priced similarly, with different value propositions. |

Choose Yogasleep Dohm Classic if…
- You want a sound that is physically loop-free (some sensitive listeners notice loops)
- You value a simple mechanical design with a long track record (the Dohm has been made since 1962)
- You only need one sound and want simple operation
- You prefer natural airflow texture over electronic sound
Choose LectroFan Evo Sound Machine if…

- You want multiple sound options (fan sounds, white/pink/brown noise, ocean surf)
- You want precise, fine-step volume control
- You travel occasionally and want a timer option
Frequently asked
Which is better for tinnitus?+
It depends on the person. The Dohm can't loop because the sound comes from a real moving fan, which some owners with tinnitus prefer. Others find the EVO's pink or brown noise options more soothing, and its fine volume steps make it easy to set a level just below the tinnitus. Sound masking can make tinnitus less noticeable but doesn't treat it; if your tinnitus is new, one-sided, or comes with hearing loss or dizziness, see a doctor or audiologist.
Does the LectroFan's loop-free generation actually sound different from a real fan?+
Slightly. The EVO's generated sound is clean and consistent, while some Dohm owners describe the real-fan texture as warmer and more 'organic.' Many people stop noticing the difference after a few nights, but purists tend to prefer the Dohm.
Can I use either for a baby nursery?+
Yes, with care. Pediatric researchers recommend placing infant sound machines as far from the crib as practical (about 7 feet / 2 meters), never in the crib, and keeping the volume low (around 50 dB, the limit used for hospital nurseries). Both work at low volume, though the EVO's variety makes it easier to find a sound you like at a quiet setting.
