Review: Anxiety from neighbor noise pollution? This is the cure. - There is nothing I can tell any of you that the other reviews don't say. Instead, I'll offer my personal anecdote. This device saved. My. Life. Well, not literally, but it definitely saved my sanity. I'm a highly anxious person who is extremely noise sensitive and vulnerable to sensory overload. Cue moving into my first college apartment, where the upstairs neighbors' every footstep can be heard amplified and bass boosted through my ceiling. (Of course, before I signed the lease, the landlord didn't mention this... "feature".) My room is right below their kitchen, so in addition to the stomping, I can hear all their yelling and banging around pots and pans all hours of the day and into the night. I was losing a LOT of sleep over this, and it ramped up my anxiety tenfold. I felt like I couldn't be at peace in my own home and dreaded having to come back here at all... My safe, comfortable space was constantly being violated by noise pollution and there was literally nothing I could do about it. As bitter as I was, my upstairs neighbors weren't technically doing anything wrong, they were living their lives just like I am. Anyway, I almost considered moving out or at least switching to an upstairs unit... that is, until I happened upon this amazing little device. I never cared for "white noise" machines that wasn't true white noise; ocean waves and rainfall isn't as soothing when you have upstairs neighbors with lead for feet. You really need a good, loud, pure white noise that masks all frequencies and that your brain can easily ignore, so it seems as if there's no noise at all. This thing was absolutely perfect for me, as it only had white noise and fan sounds (and a variety of 'em!) that can get loud enough to mask anything. I mean ANYTHING. I can now peacefully snooze through not only my neighbors' stomping kitchen antics, but also the 8AM garbage truck arriving bright and early every Wednesday. I don't wake up in the middle of the night anymore because my neighbor wants a midnight snack. I can come home after classes and enjoy an afternoon nap without disturbances. I sleep much more deeply and peacefully overall. And it's all thanks to the LectroFan. I'm telling you, if you can relate to my situation in the slightest, just don't even worry about the cost. I would honestly pay double for this if I knew how much it would improve my quality of life. Please buy this. Please. Support this awesome product.
Review: HELPFUL TIPS... for the best sound machine. - UPDATE 2014-FEB-14 -- After owning the device a couple weeks, I had some realizations about why the Lectrofan is the best product. Other white noise machines often do not allow a very full range of pitch from high to low. The Dohm, for instance, does have a pleasing sound, but it is not capable of changing pitch too much, just muffling it really, changing the tone some too. Changing the pitch is the SMART way to block out particular sounds. If my roomie downstairs is listening to music from his cell phone or a higher pitched video game, turning the lectrofan on higher pitch blocks it out without having to blast the volume. If is he is blasting bass from his stereo, the lower pitches work better. The low rumbling of White Noise 1 (lowest Pitch) may have a pleasing sound (very much like "Brown Noise," a wonderful sound that many of you researching this topic have probably heard), but it will actually fail to mask many sounds that are higher pitch. Do not make the mistake of leaving it on the lowest pitch and just blasting the volume every time you need to block out louder noise. I suppose that white noise 4-6 would be the best general sound-blocking pitches for when you have a variety of noise in the environment. This kind of use is impossible with something like the Dohm, which I used for a long time before this. There are many sounds which the Dohm will never block without trying to use brute force with the volume (and it doesn't get anywhere near as loud as the lectrofan.) And the Lectrofan can be turned so loud that your room can sound like you are living under a waterfall or something-- so it can basically block out almost any environmental sound (though of course the reality will always be that you have to have it louder than the sound you are trying to block, which is the principle of all the sound conditioners. The point is that the sound is constant and you are not distracted by all the changes in noise.) -- I didn't think I would use the fan sounds too much- I just figured I wanted the white noise. The fan sounds are actually pretty nice. They are soothing and with no perceptible loop (lectrofan told me they were actually algorithms making the noise and not any recording of a fan.) The fans do have one issue that some people will enjoy and others will not, and most people may not even notice. They do have a repeating change in bass, which I notice more than others because I am neurotic about sounds. This change in bass will be more apparent if you have headphones on or earplugs in, but you might like it as a nice constancy. I doubled up on the lectrofans so I could get a richer sound in my room (which is very cool for white noise), but unfortunately the wobbly bass sound of the fans becomes even more distracting then. Others may enjoy this. The major downside of the fans is that they do not have the same range in pitch as the white noise, so they can not do the targeted kind of sound-masking I described above. I suspect people who are not very sensitive or neurotic (i.e., anal) about these kinds of issues will really enjoy the fans, though. I guess they are probably more realistic for having this trait. -- The white noise is pleasant. Higher pitches sound unpleasant at first, but give them a chance, maybe lower the volume. They end up sounding like fans, or rain, or a distant waterfall over time. I have the lectrofans in my room on white noise, but it still kind of sounds like the rushing of air or some other sound in nature with a similar pitch; the brain kind of fills in the gaps or hears what it wants from so general a sound. The sounds grow on you. Sometimes I will be sitting here hearing it as a waterfall, other times I will hear the same sound as air from an airconditioner or a huge downpour of rain. It is a really interesting phenomenon. Or maybe I am just crazy. -- The customer service was great. My first purchase would rattle when I turned the volume up to the highest levels. They sent me a replacement with two day shipping promptly with no questions asked. The new device gets VERY loud (way louder than the Marpac Dohm, it's main competitor) without losing quality. -- I owned a Dohm, but do not use it anymore. This device is more efficient, smaller, louder, and produces a better quality of sound and a wider range of sound. My Dohm started rattling after a few months and so I looked for a better product. Thank God this had been released recently.

## Questions & Answers

**Q: Is this better than the Marpac Dohm-DS Dual Speed Sound Conditioner? (it's currently the #1 best seller in sound machines on amazon). Why yes/Why no?**
A: I had an original Marpac 330 sound machine which was a great machine and lasted for 30 years.  Ten years ago I tried to replace it and the new machines had a very annoying sound loop.  I called Marpac, they were so nice, sending me machines but they all had that problem.  I tried a Sound Dohm at Bed Bath and Beyond and it just didn't have the volume of their older machine.  Wish they still made that version.

**Q: Anyone use a real fan first and then switched to this? Why did you switch ? I use 10" solder exhaust fan.**
A: I like this better than a real fan because: You have 10 different fan "frequencies" to choose from. Can experiment to see what masks the annoying sound you are trying to cover up....Also has 10 different "white noise" frequencies too...Can adjust volume quite a bit more than with a fan...and is also good if you need big wooshing fan sound to cover up a noise, but don't always want a fan blowing air around. I hope this helps! I use it in an office environment- it has been great. (Before I was using fan - sometimes had to use 2...got very windy.)

**Q: How is this any better than just hooking a speaker up to an iPod or phone and playing white noise audio files? Or just using an actual fan?**
A: I currently use my Apple Homepod to play white noise in our bedroom.  Apple Music has a number of white noise tracks available.  I use a track off an album by "Dr. White Noise", I made a "White Noise" playlist on iTunes, I copied the track ("Soft Dehumidifier Fan Delight")  12 times so it will play for 12 hours (the track is 1 hour long).  It works and sounds great.  You could certainly use speakers hooked up to your phone or iPod to accomplish the same thing.  However, if you needed to purchase speakers to use with the phone/iPod, it seems like you might as well get this unless you want to use the speakers for music, etc. in the bedroom.  This device would certainly be easier to use than hooking up speakers each night, plus it would likely take up less space. That said, I am thinking about trying this device too as we could use it in our Airstream travel trailer when we are traveling.

**Q: Can it run on batteries? If so, for how long?  Also has anyone used it overseas?**
A: Considering the small amount of power it uses (2.5 W) it should be possible to run it off of any device that can steadily supply 5V at 500 mA DC. As such, if you can find a battery pack that can output 5V @ 500 mA and has a USB socket on it the Lectrofan should run off of it no problem. As for how long it can run off of a battery pack, it would depend on the rating of the battery pack being used.

### ⭐⭐⭐⭐⭐ Best Sound Machine Ever!
*by E***S on April 30, 2026*

Favorite sound machine ever- we have 4 in the house. It is so effective has great volume versatility and my kids (and my husband and i) sleep so soundly with it. There is a 60 min timer option but we just always leave it on. There are many different white noise and fan sounds to choose from. We love it- highly recommend! It’s also very easy to travel with. We also love their wireless one!
