LectroFanEVO 09

REVIEW – I’ve seen “noise machines” in doctors offices. Maybe you have too! Years ago I bought one for a family member, but the LectroFan EVO is an all-electronic devices with 22 different sound options. Time to put them side by side.

What is it?

Unlike competitors that generate mechanical noises, the LectroFan EVO has no moving parts with easy to use controls, including a built-in timer.

LectroFanEVO 01The sounds are designed to reduce the intelligibility of voices and noises around you, increasing privacy.

There’s not a whole lot to the EVO. Plug it in and choose a sound you prefer. I prefer the deeper “brown” noise. The sound is non-directional so it’s less obvious where the sounds are coming from.

Curious about the competition? I shot a video of the popular DOHM sound generator, which features a mechanical fan-like mechanism. The DOHM sound is adjusted via vents on the top and sides.

Unlike the DOHM, the EVO has a sleep timer. Each press adds one hour. A short rising tone provides feedback to your selection.

I had a short power outage recently and discovered the EVO had turned itself on. This is a feature! Great if you’re using a remote switch and you have the EVO tucked away somewhere. The auto turn-on function can be disabled.

I did find the DOHM’s mechanical whirly sound was slightly more pleasing. It’s difficult to quantify. However, the EVO isn’t bad, either. It’s a matter of personal taste.

What I like

  • Solid-state (no moving parts)
  • Many different sound options- there’s probably a sound you like
  • Timer and auto turn on when reconnected feature
  • Incremental volume control

What I’d change

  • I still slightly prefer the “feel” of the old-school DOHM’s sound, but only by a little.

Final thoughts

If you want the most adjustability and options in a noise machine the LectroFan EVO is hard to beat.
